How end systole coincide with end of T wave ? Please explain if possible End systole should also coincide with beginning of T wave ( diastole starting)
Dear Satyendra, thank you for your question. Remember that the mechanical contraction of the heart always lags behind the electrical depolarization. Therefore, the systole continues to occur after you see deflections on the ECG. Initially, both the atria and ventricles are relaxed (diastole). The P wave represents depolarization of the atria and is followed by atrial contraction (systole). Atrial systole extends until the QRS complex, at which point, the atria relax. The QRS complex represents depolarization of the ventricles and is followed by ventricular contraction (that ends at the end of T wave). The T wave represents the repolarization of the ventricles and marks the beginning of ventricular relaxation.

is there a subtitled version of the video available? I don't understand it, as I'm a foreigner. Thank you.
Unfortunately, not for this video.
