The ECG Course - Waves & Complexes

[@gingermullinax8515]

Please don't ever remove these teaching videos from youtube. I couldn't pass rhythm and ACLS without viewing them first. I love the way you teach.

[@denisehunter6771]

Thank you for your thorough explanation. I am a certified EMT-I. I've worked in the ER and now working at a Cardiology Clinic. This is such an excellent review for me. Thank you again!

[@aldodeferrari7438]

Thanks so much for these lessons! I love how you correlate what is happening in the heart with the ECG waves. I really enjoy your videos!

[@hannahhoskins178]

Great analogy with the angle of view considering the human profile.

[@darraghm78]

thank you so much i am from NZ and am training to be an EMT these videos have been such a big help thank you again

[@lisaduke5326]

excellent help while I study to be an rhythm analysis tech. thanks for the clarity.

[@curtpiazza1688]

You have a great thing going here!! Thanx!!

[@rosalietumacder1993]

Thank you so much, very understandable....

At 12:37, if we are looking from the perspective of lead II, why is the qRs complex negative? Doesn't ventricular depolarization cause a positive wave to move towards the bottom of the ventricles, in the same direction as lead II?

[@Meducator01]

Sergey K I would recommend you watch the ECG Axis tutorial. Axis deviation can cause alterations in polarity.

[@JuicyCharon]

Why does the Lead II have its ventricular depolarisation going negatively from the isoelectric point if the wave of depolarisation is going towards Lead II. I'm referring to the graph at 15:44. Thanks for the video though.

[@melvincaldwell2087]

+L.M the high amplitute represents some sort of enlargement of the heart. limb lead one is observes the lateral region of the heart. Standard limb lead 2 observes the inferior region of the heart. They are reciprocal in nature. Those 2 limbs leads don't give a good enough picture of what's going on. Some sort of hypertrophy or inflammation due to the high voltage. Basically they look at opposite sides of the heart( almost) and are reciprocal thus why the R waves are facing opposite ways on the ecg strip.

[@JuicyCharon]

+Melvin Caldwell Yep I understand. I didn't know at the time I posted this but after another year of med school I got the answer. It's always nice to be reminded of how stupid I was a year ago,

[@melvincaldwell2087]

lol yeah I saw the date of the post after. Your power level has increase significantly since then.

[@nuigmed3306]

are the R waves not opposite to each other in the graph when they should be both positive?

[@annlanzilotta2609]

Thank you!!! Very helpful this Ekg course is tuff.. God Bless You!!

[@walaabdeljawad1439]

actually thank you !!! this whole course is amazing
