Antiarrythmic Drugs Part 1: The Physiology of Heart Rhythm

With some understanding of drugs that manipulate cardiovascular function, let's start to look at heart rhythm. Many drugs are focused on this, but before we dive into those, how does the heartbeat work? How does the body ensure a rhythmic heartbeat so as to supply the body with oxygenated blood? Let's get some basic information!

Thank you Dave. I have a pharmacology exam on the cardiovascular/renal drugs and this video (and others) are helping me understand the MOA a lot better 🙏.

My Arrhythmia was so drastic that 17 years ago they did what they called a double-lasso pulmonary vein ablation - over 6 hours of burning. OK for a while. This year it "failed" and it was pretty horrible. Took three days in hospital to stabilize enough to send me home to get drugged up enough for the Chryo-balloon ablation (not for pussies) - followed by a couple of weeks of full-blown hell to gradual improvement to complete stability (6 weeks now - better than before the failure - doing a 5K tomorrow, age 78).

Sometimes I click on Dave's videos when I know it's a tutorial just so I can listen to the 🎶 intro jingle 🎶. I like to harmonize with it. Today I went with the lower octave 💙🎶

[@jbirdmax]

All I heard was: Transistor/capacitor switch controlled through a Zener diode and rectifier system to control microelectronic pulses at a predetermined frequency.

[@waelfadlallah8939]

That's actually very similar to what was explained

[@waelfadlallah8939]

These are the videos which i like the most to be explained by you, Prof Dave. Hope you'll concentrate more in uploading the genre of medical subjects 😊

[@axjaxx]

Would love to see a video on POTS from you!!

[@Ghlostyc]

Not sure if you’ve done more videos about topics like this, but if you ever happen to have an interest in teaching about normal drugs and their safety/efficacy(?), I come from a highly conservative/religious household that demonized all forms of mental health drugs, pain meds, etc. much love thanks for the content!

[@andrewjones6693]

Very timely for me, Dave, as I was recently put on Metoprolol Tartrate. I look forward to your subsequent videos! 🙂

Next time I see my cardiologist, I'm going to ask her, "How is my bundle of His"?

[@rudolfambrozenvtuber]

Would you ever consider doing a rhetoric series? I'd appreciate a way to continue off the video Modern Hermeticist (someone of...different persuasions but who nevertheless provided a strong starting point I feel) made a while ago

[@FBIINFORMANT-bx8uy]

Hey can you do like quizzes to go along with the videos like Sabine does? Idk just a suggestion.

[@Rama.24]

I would be so good to see you teaching mechanics also.. If it happened though

[@eingyi2500]

Been subscribed to you for a while. I have Long QT syndrome and take beta blockers so I clicked very fast 😂

Have to admit, when I saw "Antiarrythmic Drugs," I thought about a drug one could take to play the drums better.

I have experienced bradycardia, tachycardia, hear block, congestive heart failure and cardiac arrest. Zero stars. Do not recommend.
