Diagnosis of SVT in the EP lab 

AND GIRLS :D

Thanks so much! 🙏 Yes indeed, lots of time was spent selecting examples, displaying egms in a consistent way, annotating and illustrating the examples, deciding on sequence/grouping, and then narrating it all! Glad the effort paid off! 😁

I hope it makes sense, and I hope it helps!! 👍

Thank you so much!!

@@dr.joshuacooper-arrhythmia9917 I consider my PPT skills on point. But you sir.... take a bow.

Best. Comment. Ever! ❤️

You made my week!! Thanks for such kind words!! 🙏

Thanks so much for your kind note!! 🙏

Sorry for the delay! I hope it's helpful!

And that's why i made it! So glad you found it useful!!

Thank you so very much for your note! Thank God my health remains good (5 years cancer free!), and i have lots more educational stuff planned! 👍

We just had atypical AVNRT with a patient today 👏

OMG, thank you so much for the feedback! You may be the only person to attempt to watch it all the way through in one sitting! 🤣

Clear labels, large font, showing one concept at a time... Makes a difference! 🙏

Yeah, I'm sorry it's been so long :(

Glad you found it helpful!! 👍

Thank you so much for your amazing note! Good to hear this video can be helpful even for someone who's all thumbs! 🤣

The international interest in this and other videos has been so wonderful!! Thank you for your message!!

Sorry for the delay!😅

Awww... Thanks! ❤

Yes, in order to verify the diagnosis of svt, a heart monitor has to catch the tachycardia while it is happening. Nowadays, there are different types of heart monitors which are much easier for the patient than in the past. One of the simplest is a single sticky patch that sticks to the top of the left chest. No wires, no battery recharging, no daily maintenance, waterproof so no restrictions on bathing or showering, and it saves everything for a full two weeks. There are ways of catching fast heart rhythms that happen less often than that, including smart watches that can record the heart's rhythm, and the Kardia Mobile app device which someone can keep forever and take a recording while symptoms are happening.

Could you please clarify which part of the video you are referring to? At the 1:45 point, it is a text slide, not showing electrograms. Which timestamp did you mean?

Sorry at 1: 37 atrial activation slide

Ah, i think you're referring to the case example at 1:37:45. In this case, earliest atrial activation is *neither* in the center of the heart near the AV node, *nor* over leftward in the left atrium near the distal CS catheter. Instead, earliest atrial activation is way over in the lateral *right* atrium, nearer to the HRA catheter and further from the septum/AV node. And so this is not central activation, but rather it is "right-sided eccentric," meaning originating at the lateral right atrium. I realize I am using the term "eccentric" differently from what people usually say when they are referring to the earliest signal being over at the lateral left atrium (AKA left-sided eccentric). But both lateral right atrium and lateral left atrium early activation can be seen as "eccentric", meaning not concentric where the septum is earliest. You are correct that the coronary sinus catheter alone has a concentric pattern, but when you think of both atria in their entirety, we also have to take into account the possibility of non concentric activation way over on the right, where the only recording catheter we often have is the high-right atrial catheter.

so sorry for the delay!!😐
