Advanced EKGs - PACs and PVCs (i.e. premature beats)

How to identify and describe premature atrial and ventricular contractions.

It's been a long time since I've added to the EKG playlist. I know some of you have been waiting for a video on VT - I hope to post that next week. I'm still trying to track down one final example to include in it. Consider this video on PACs and PVCs a warm-up!

[Sasbie]

Are AFIB and PAC the same thing? And why is AFIB considered more serious than PVC?
When my cardiologist (actually I diagnosed them with a Kardia device) diagnosed my PVCs, he offered me a beta blocker if the PVCs bothered me. That was it.

Dr. Strong! you've done it again! you're amazing! A gift to med students, doctors and patients all over the world!

I thought inverted p waves is pjc??? 6:19

Excellent presentation, doctor Strong! I was diagnosed with PVCs and now I understand that when it feels like my heart stops, it's called a compensatory pause. I also have that strong pulse afterward.

Thank you for this video (and for all your videos)! I have very frequent PVCs. I like to know as much as possible about my medical conditions, but the learning curve for the layman is in regards to electrophysiology is... very high 😅. Your videos have been super helpful to me in learning about the heart and how it works. Thanks for all your hard work, it's greatly appreciated!

I feel the PVC, and I feel the harder beat after the pause. In other words, I know the heavy beat is coming because I feel the PVC first. When the PVC happens, for a split second, I feel a sensation through my whole body, hard to explain, but its kind of a feeling of my life stop just for a second, then I expect the heavy beat to get me back to normal heartbeat. At the time Im making this comment, I'm in my 3rd week of horrible PVC episodes. Once in a while I get a relief for a few hours, but they seem to start up again when I first wake up. Had them all my life, but the last few weeks have really sucked!

Premature "beats" that raise a pulse (as in the arm artery) vs. premature beats that don't raise a pulse?
Premature depolarizations that seem to be close coupled/fixed interval after the previous depolarization(s) vs. ones that seem to occur randomly but not quite as immediately after the preceding depolarization?

How about a "premature beat" of any kind that occurs after a longish interval after the preceding depolarization at a time the heart rate is very slow, say, 40 beats per minute? As a form of escape? Is that when a healthy heart produces a junctional beat?

Do premature beats that don't raise a pulse waste energy of the heart and contribute to worsened heart failure in heart failure patients? Say if someone had an EKG rate of 70 per minute but 20 of the ventricular depolarizations were PVCs ?

I have a special spot in my ❤️ for cardiology!!
Thanks for the video!

Many thanks for the interesting & helpful video

How come a ventricular contraction doesn’t follow the retrograde p wave? 10:06

[aleksandardzunic]

03:30 - PJC strip shows bipolar P wave form, which could indicate enlarged right atrium, assuming, by the QRS complex, that it is V1 lead. If lead III has been shown with negative T wave, it could indicate pulmonary embolism.
Please, indicate the lead used for demonstration of the particular issue. Thanks for your great work in terms of education of the students who studies medicine, as well for us (geophysicists) who suffered AF and PE and who purchased ECG machines to be able to monitor heart status and interpret the results, based on excellent lectures you've created so far. Thanks again!

Is the non compensatory pause in PACs the same? Or will the p-p interval be LESS than twice?

[bhavnasingh]

Thanks a lot for your efforts to make us understand....before this video...I was really very much confused how to recognise or Identify PVCs or PACs in EKG....but now it's really helpful to Identify the same....hope you keep Making such kinda helpful videos...Thanks a lot dude....👍🙃

[davidpowell]

Would the final EKG strip be easier to figure out (detect that there are hidden p waves/2nd degree AV block with "atrial tachycardia") if the other EKG leads tracings were presented as seen on the physician's 12 lead EKG machine printout ?

[fruitlion]

Are non compensatory PVC pauses more dangerous?

[ravipandey]

Keep uploading sir...always enjoyed and learned from your videos...keep it up 👍

[youssefbenyoussef]

hello can u explain us how to know if it is a PVC or abberancy ( a video will be great thx )

[brentkennis]

Just curious, what level of knowledge is this? IM resident? Cardiology fellow? EP fellow? Seems rather nuanced

[sunving]

Thank you Dr Strong, wonderful lecture as always.
