Understanding Supraventricular Tachycardia (SVT)

It took 4 coronary specialists in 4 countries over 50 years before I got correctly diagnosed as having SVT. I was usually given sedatives being regarded as an anxious female, then adenosine intravenously to correct heart rate. A brilliant doctor visiting Monterey hospital diagnosed my SVT as an electrical problem and gave me a catheter Ablation all done in 10 minutes!

[@leoprdsoul1]

Can I ask about the ablation? How was it? Did it feel weird afterwards? Are there any scary side effects? (Thinking about getting it done) Thanks

[@wholeNwon]

Astounding. It's usually a diagnosis at the intern level...really.

[@heathgato9062]

It’s concerning how often doctors will dismiss SVT episodes. Mine became very active almost 10 years ago. Took providers 5 years to refer me to cards. I was always told I had medical anxiety and that if I’d stop focusing on the “funny feelings” in my heart, the sensation would “go away” and I’d forget how scared I was. That’s not how SVT works but as a stupid pleb I leaned there was no point in trying to reason with MDs.

[@cabaelz]

​@@wholeNwonIt may not have taken this long for a diagnosis now. My own took a little under 20 years. It's the problem with being a woman, anxiety and/or panic attacks is the first thing everyone thinks of. Younger doctors, and cardiologists of any age, are much better at not brushing my concerns off

If you are in an episode, start acting like you are trying to poop and pushing really hard. In an episode, bending over and violently coughing can help get you out of it If you are in it for more then 20 minutes and these techniques haven’t worked to get you out, go to the hospital. If you dont have someone to drive you call an ambulance. driving can be stressful and you dont want to faint while driving.

[@cjj7107]

I tried those techniques but there are just some SVT episodes that will no longer stop unless you get adenosine injected in the ER. Had two of those episodes two weeks apart so I decided to have an ablation and it was done two days ago. Still monitoring my heart now. Fingers crossed.

I’m a victim of Pulseless Ventricular Tachycardia where my heart is beating so fast, you can’t feel a heartbeat. It’s been caught at 197bpm but that’s only the beginning. They discovered I have a very rare heart defect I was born with, known as Wolff, Parkinson, White Syndrome. That’s only part of the problem since I also get bradycardia and A-fib plus spontaneous blackouts. I’m so rare because I have a short circuit between the SA node and the AV node besides the normal pathway. So my poor heart gets two different signals and messing everything up. I now have an expensive loop heart monitor implanted in me that checks my heart 24/7. That’s so my Electrophysiologist can find each heart cell involved in the short circuit. In a rare procedure, he will have to destroy each rogue heart cell one cell at a time to stop the short circuit from happening again. That could take up to 10 hours and I cannot move, so I’ll be strapped to the table unconscious. Btw, I’ve now lived with this heart defect for 78 years, an accomplishment for this poor heart still beating in my chest.

[@hanz5300]

wow! That's amazing, sir! Even though you've heart abnormalities since birth, you still live up to 78 years old!! I'm currently 14 years old and I have tachycardia my resting heart rate range is between 90 and 120 bpm.. I was too concerned, but your situation before was a lot worse than mine

[@robertmiller3810]

@@hanz5300 Hanz, my case is rare and you should not judge your tachycardia against mine. My defect alone is one in a million, the odds of me living to my age is probably one in ten million. Back in the 1950’s when I was 10, nothing was known about heart rhythm problems when I blacked out for the first time I can remember. All I know is one second I was okay, the next I was on the ground or floor, wondering what happened. There are a number of things doctors can and will do for you. Medications is one, there are several things you can do to ease up you triggering your tachycardia. Anxiety is one thing, do not constantly think about it, stress is another trigger. Stop drinking anything with caffeine in it. Anything with a stimulant like caffeine in it can trigger it. So you will have to live a more calm, peaceful life. Of course I knew none of this at your age and I suffered because of it. I hope doctors can calm your heart down Hanz but you have to work on keeping yourself calm. By the way, I’m in the United States if you are wondering. Good luck, let me know how things work out for you, just keep track of this post on You Tube.

@@kailashmanas3501 What would you like me to talk about? Many things can cause tachycardia which your doctor should have explained to you. Chocolates are just one thing, like I already explained to the last poster on this subject. Since you have access to the internet, you can research for answers to questions you may have. When I was your age, I used to plan things years in advance. Now I cannot even plan what I’ll do in the next second because my birth defect can stop my heart between the first half of a heartbeat and the second half. I cannot worry about my life ending in an instant because stress can trigger tachycardia. I am not a doctor so I cannot give you medical advice but I can try to answer questions you may have because they have happened to me.

[@geraldfrieberg7921]

Wonderful video, and extremely well explained. I had a case of atrial flutter (HR about 120 to 130 BPM). This was very alarming, as my resting rate is normally in the high 50's. My cardiologist performed catheter ablation, and thus far (after 2 years), the flutter has NOT returned. I am reasonably sure that this was caused by fibrous tissue in my heart as a result of alcohol use (2-3 IPA's per day for several years). I think alcohol, even in moderate amounts on a regular basis, causes heart damage. Needless to say, it has altered my view of moderate alcohol use "being good" for the heart. That belief, IMHO, is perpetrated by the alcohol industry itself. So, hopefully others can learn from my own experience. I am very fortunate to still be here, and had a great physician who helped me with this issue. I was 66 years old when this ablation occurred, and in otherwise good physical condition (not obese, 5'8", 145 lbs, and a regular exerciser). Be VERY careful in buying into the idea that small amounts of alcohol, regularly, are good for you. Not everybody !! Do some reading up on this subject in documented medical literature and you will see that I am correct.

My first two episodes were when I was drinking heavy. I haven't drank for nearly 3 years but I had a 3rd episode a few weeks ago. I was surprised because I thought after I quit drinking they would go away. I later suspected the last one was caused by taking a high-dose turmeric supplement. I can't be positive but the timing made sense. My cardiologist recommended the ablation but I felt I wanted to research first. It's interesting and insightful to hear others' experiences.

My doctor taught me to do the Valsalva manoeuvre by holding my nose, tipping my head towards my chest and blowing hard while keeping my mouth shut. I've found that doing this repeatedly during an SVT event bought my heart rate back to normal - a bit lower each time I tried it. Having an Apple watch has been useful too - it picked up I was having an SVT event before I noticed it was happening.

Ive been diagnosed with PSVT and have been having episodes for a while that only started when I turned about 55 years old, Im 65 now. After trying all kinds of ways to convert back to regular heart rates Ive found something that works 100% of the time for me. Prior to finding this, Ive had to call 911, had adinosine, been to the ER 2X. If I can catch it before it starts, which Ive done a few times I can stop it sometimes with a cartoid massage. Im very intune to my heart now since this started happening. If I fail to stop it when I feel it coming on then I go lay on my back with my feet up in a quiet place and close my eyes and just breath and think of calmness. This has been in the back of my SUV, on the floor in front of the couch, on the floor in my shop. It works with in 3-5 mins, every time. I think the key is to just calm down yourself.

From what i´ve seen in patients I feel that the ablation often produces great results. But as with all invasive procedures there is a risk of complications and because it is the heart you work on during ablation the complications may be very serious. Also even if there are no complications nobody can guarantee that the ablation works 100%. That being said if it is truly affecting life quality I would recommend ablation.

[@Dee-rt6vc]

I just had my second ablation. My first was done in 2001 and it came back in 2019. I will cross my fingers that it does not come back this second time around. I'm happy with having my second.... Good luck!!

[@welcometorosaritob.c.5489]

I have had those episode since 2021, I didn't know what was happening to me until my heart went out of control, I instinctively take a deep inhale and exhale I feel that exercise really helps to slow down my heart bit .

[@_danila5185]

Are you better now?

[@emilyeguia8608]

I was diagnosed with SVT when I was 14 and had an ablation. I felt amazing afterwards for two months. Then problems came back and here I am ten years later with IST and POTS. 🥴 tbh though I’d rather have pots than svt. Every episode with svt I thought I was going to literally die. With pots I just feel like crap a lot! 😂

[@rachellydy3367]

Aww that sucks! POTS is related to autonomic nervous system dysregulation. My daughter has this as well as some of my patients. Have you been assessed for Ehler Danlos syndrome, autoimmune illness (like Lupus), and Lyme disease? All can contribute to POTS.

[@harshadskulkarni]

Thanks for such a clear explanation. I'm 30 yo Male. I had SVT. I went through ablation in the year 2015. The ablation was partially successful. The doctor then prescribed me Metoprolol and said this is help clear rest of the issue. It's been 6 years since ablation and I still face irregular heart rhythm on a daily basis. My SVT episodes are rare now (because of the medication) but the irregular heartbeats are annoying and scary. Please suggest a permanent solution. 🙏

[@ZeroToFinals]

Not sure about this one - I always assumed it was something to do with the brain sensing the asystole and panicking. Interesting question!

[@aoife2089]

Idk much about the physiology, but adenosine caused me a horrible stinging heat in my heart and i felt my heart shutting down and stopping (something I assume is the same as heart attack). Even when warned about this feeling in advance, it still catches you by surprise, I remember reaching out to the bedsides in pain and fear. (The adenosine didn’t even work for my svt, the next thing they did was put me to sleep and I woke up ok).

I have been diagnosed with SVT. It's pretty scary when it happens. My electrocartioligst pinned it down because I thought I had AFib. After wearing a heart monitor for a month they discovered I had SVT. Still scary and very uncomfortable at times. I only get episodes every once in a great while. My last episode was brought on by taking a cold medication. NEVER again! I will suffer thru the cold next time. I may need to get ablation someday, but O hope not.

When Valsalva maneuver doesn’t work... ice cold water does. As a person with this condition and a mother with AFib... we both have found drinking ice cold water or even dipping your face in cold water will often reset the rapid heartbeat. Sometimes instantly.

"My wife has been dealing with episodes of SVT (Supraventricular Tachycardia), where her heart rate can shoot up to 230 beats per minute. Recently, we discovered that chanting 'Om' for about 5 minutes whenever she feels her heart rate rising helps bring it back to normal. It's a simple and calming practice that has made a real difference for her. While this has worked for us, please remember to consult a healthcare professional if you or someone you know is experiencing similar symptoms."

[@sheilakilroy441]

I was diagnosed back in 2018 with SVT. I had had an episode a couple years prior and it lasted about 10 minutes. I didn’t know what it was or understand it and I just tossed it up to stress I was under. Then in 2018 I was working at Aprl Restaurant and I was just presenting a guest it happened again, but this time it was worse and thank God the GM on duty had a blood pressure cuff and when he checked my heart rate I was it 248 BPM, 911 was called of course. My husband was in the ER room with me along with eight doctors, not nurses not PAs,, needless to say it was the scariest experience of my life. I’ve had a couple few since then. One episode my husband brushed me to the hospital and alerted the staff of what was happening and there was a doctor just happened to be right there and he invented or created or whatever the medical term is where they discover a procedure and that vagal maneuver that he medically came up with was used on me that night, it didn’t work! Ha ha. But needless to say to all my SVT family my heart goes out to you, he he.❤

I find i am often short of breath under no load or short of breath under a load. And then sometimes i find i am not short of breath under either of the above. I have controlled hypertension and and also restricted blood flow to both my feet at times the feel like ice block even on a hot summers day . I often experience a rapid heart rate over 120 or above 100. The last highest rapid rate i captured was @ 159bpm but usually will be 125 to 139bpm. Thankyou.

[@hmmc9262]

Nice vid, but a warning about carotid sinus massage is required as it has a risk of embolic stroke in those with carotid plaques. Best avoided and stick to modified Valsalva in the conscious patient

[@LazyDorman]

Since I was about 13 years old, I sporadicaly felt an unusual sensation feeling in heart (a single harder heart beat), which set my entire body on alarm. I couldn't tell what it was and I was just living with it. I visited a few cardiologists and they said it was all fine. Now when I am almost 30, I had a really bad flare-up of this sensation which wouldn't stop. I went into panic mode, and we called an ambulance (Because my chest felt like a drum). They made EKG and drove me to the hospital, the doctor said it was SVT. They did a few more examinations (Holter, USG, etc), and again said my heart was okay. My SVT are tough to diagnose due to the frequency of occurrence (Except the time I was in the ambulance, which showed clear SVT non-stop). My cardiologist suggested taking iron, and magnesium supplements which really helped, and the frequency reduced from few per day, to maybe one per week (single out-of-sync heart beats). Also no need for professional medication or ablation due to frequency.

I've started to experience this now at 31. Woke up with my heart at 150bpm for no apparent reason and went up to 180. Called an ambulance (I'm in England and it's free for me before you scold me). They did blood tests, ecg, scans. Everything was fine. Went back a couple months later with chest pain. Lots of tests, everything fine again. Been having about four episides a week now with mild chest pain. I've always had a slightly too fast heart rate, but these episodes have decided to start happening lol. Gonna talk to my doctor about solutions, for now I use a beta blocker (propranolol 20mg) to lower heart rate if it's bothering me too much, brings it down to 75bpm. It seems the catheter ablation treatment help others the most.

And about 1 year later he was able to follow his army plan! He was stationed in Germany after basic and had 2 guys in his battalion actually die during PT a couple of days apart. Due to exactly SVT.. super CRAZY…10 years later he’s still 100% fine!
