Great video, Dr Eric. The EKG videos are the ones I like the most, and they've helped me a lot so far. Please keep up the excellent work.

Dr strong, how do you differentiate between sinus pause and sinus arrythmia? How do you know if it is respiratory if a patient brings an ecg to your office?
@drsal60994 жыл бұрын
Excellent video.. without doubt the best video I have seen.. I have been trying to understand sinus pause, arrest & Exit blocks. I have noticed that in practice it's quite difficult to distinguish between them. Could you tell me a how to distinguish between sinus pause or arrest from Second degree Type 2 SA block. Is it just on the basis of PP interval?

SA nodal exit block is AV block? From the 3 degrees of block same like AV

This was very educational. Please include more ECG examples.
@StrongMed9 жыл бұрын
Ivan Petrosevic Thanks for the feedback. I try to balance between providing enough examples to be instructive, without making the videos too long. But I completely appreciate that both repetition and seeing numerous, slightly different examples of the same diagnoses are both critical to becoming skilled at reading ECGs. Also, I have a limited number of examples myself, particularly of the less common diagnoses, since I only include the "pure examples": ECGs which demonstrate only one significant finding and which are free of artifact. Once I've covered all of the ECG topics I hope to (another ~13 videos to go), I'll take the leftover ECGs and rhythm strips, and probably create one or more practice videos like the "Practicing Tachyarrhythmia Identification" and "EKG and Heart Murmur Review" videos, but inclusive of all diagnoses covered in the series. Thanks for watching!

so how do you differentiate sinus pauses from SA nodal exit block 2nd degree type 2?
@StrongMed2 жыл бұрын
In sinus node exit block 2nd degree type 2, the pause between P waves is exactly twice the normal P-P interval. With sinus pauses, the pause between P waves is a seemingly random duration.

I don't know where else to ask this but, how can you tell the difference between sinus exit block and 2nd degree heart block type 2? Is sinus exit block more of a one time thing and 2nd degree heart block type 2 a rhythm so ongoing? How can you tell the difference between the two on a 6 second strip?
@StrongMed3 жыл бұрын
In "2nd degree heart block type 2" (which implies AV block, since it's much more common than SA block), there are P waves that are not conducted. In other words, only QRS complexes are intermittently missing. In type 2 sinus node exit block, there are missing P waves in addition to the missing QRS complexes. Both AV block and sinus node exit block can be either temporary or permanent.

@@StrongMed Thank you so much! I totally forgot about the p waves in 2nd degree type 2!
@trieudeptrai9 жыл бұрын
What is the mechanism behide SA nodal exit block, and how we can distinguish between it and AV block, especially in case of type 2 of 2nd degree block because I feel like it look indentical to the type 2 of 2nd AV block? Anyhow, thank you so much for sharing and teaching us.
@StrongMed9 жыл бұрын
trieu ho Regarding how to distinguish 2nd degree SA exit block and 2nd degree AV block, in AV block there are non-conducted P waves within the pauses in rhythm, while in SA block there are absent P waves. Regarding the specific mechanism of SA block, I didn't know the specifics. So I consulted my wife (an electrophysiologist), her collection of EP textbooks, and a brief literature search, and I am still unable to come up with anything more substantial than a list of etiologies.

The heart block will have EKG changes. 1st degree will have a longer P-R interval, anything longer than .20 is a 1st degree. 2nd degree type 1 will have progressively longer P-R intervals till the dropped beat then resumes this pattern. 2nd degree type 2 will have normal P-R intervals with occasional P wave with no QRS complex. 3rd degree will have no correlation between P waves and QRS complexes and more than likely will have wide complexes due to the ventricle conduction. This is a great video that explains the different issues of the sinus node well, I just thought I would throw my 2 cents in as well.
@adinsx886 жыл бұрын
Zachary Taylor he was talking about SA node block, you are discussing AV node block.
@sepehralaie671611 ай бұрын
Sorry to bother you doctor, but I don't get the part about" pp intervals progressively decrease". You said it's analogous to decrease in RR intervals in type 1 of second degree av block,I also don't get this one! can you explain why the RR intervals in type 1 of second degree av block must decrease?It's more logical that RR intervals should increase each time,because SA node sends its impulses regularly but each time it takes more time for the impulse to reach from SA node to the ventricles, so RR intervals must progressively increase prior to the pause! 😢

2nd degree ( either) and respitory sinus Arrythmia at the same time = tricky interpretation.
@piotrdominek96135 жыл бұрын
For the sake of discussion.. why PP interval shortens in 2nd degree SA type 1 block? Logically if there is a delay in propagation, then each following P wave should come delayed and PP should increase. In the example looks like SN is discharging faster and faster..
