Dr. Nicholas Tullo, a heart rhythm specialist, presents this lesson for the ECG Academy. This instructional video explains where the ECG signals come from. The cardiac conduction system events are related to the P-QRS-T pattern in the electrocardiogram. The content of this video will help viewers to understand how an ECG is produced.

thank you very much, whenever i start reading about ecg i get bored and confuse, but watching your simple informative videos kept me to the screen. this my first time to comment on you tube video because i really want to thank you for the knowledge i learnt from you
This is great! thank you so very much!
You're welcome, Susan! I'm glad you liked it. I have many other videos that you can watch on RUclips and an entire course on my website, ECGAcademy.com
Very informative.
Thanks, Swerte!!
Very Nice Presentation
Thank u
The His bundle electrography is part of an electrophysiology (EP) study. You are given a mild sedative before the test. An intravenous catheter (IV line) is inserted into your arm so that you can be given medicines during the test.
Thank you! it is very informative. I
His bundle electrography is a test that measures electrical activity in a part of the heart that carries the signals that control the time between heartbeats (contractions).
Wow, thanks a lot. Now i dont have to waste time reading a bunch of pages on the intro of the EKG.... Cheers!
thanks this really help with understanding ekg
Yes. I agree very helpful thanks for taking the time to do this. Also I was asked a question earlier maybe you could help me with? what would cause a regular, strong pulse at carotid and brachial sites to be within normal range (60-65, resting rate, done a few different times) but when taken measuring the radial pulse (done at the same time) to be very irregular, thready, slow, and weak in each wrist?
In both cases, are the PF on the right endocardium isolated so that the activation in the right myocardium arrives only through the PF? Are generally the LBB and RBB (and the PF) able to be activated from any wave travelling from the working myocardium? Or the activation can only take place from the fibers towards the working myocardium?
Thanks a lot for your response
well i want to ask a question
how we could manage to record an ecg of the heart and it is covered with fibrous layer (pericardium ) which acts as an insulator ??/?
Dear Dr. Tullo,
I would like to ask you about the role of the PF and the depolarization of the septum ... I read somewhere the Q wave reflects the depolarization of the septum, which should occur from left to right (since the LBB conducts faster than the RBB, am i right?) ... (cont in next comment)
What i cannot figure out still if the depolarization wave in the septum starts from the ends of both posterior and anterior LBB, and then it continues to the PF activating the left myocardium and the activation travels through the septal myocardium from left to right? Or there are some junctions along the LBB starting myocardial activation before the signal arrives to the LBB ends? (cont next post)
good vedieo
Mine is rS or Qr in ECG report that I got from Apple Watch. Can you tell me is it normal or not?
