A Comparative Study in the Use of Brachial Photoplethysmography and the QRS Complex as Timing References in Determination of Pulse Transit Time For more than a century, there has been interest inpulse wave velocity and pulse transit time as a possible metricfor blood pressure and other cardiovascul...
This is characterized by a PR interval that progressively lengthens until the P wave is not followed by a QRS complex—the QRS has dropped off after the P wave. Type II (Mobitz II) In this type, some of the electrical impulses are unable to reach the ventricles at all. The non-...
The largest increase of preoperative ejection fraction value was in the posterior group (68.7%) compared to the lateral (42.2%) and anterior groups (19.8%) (plt;0.01, A vs. Pamp;L; P vs. Aamp;L). In the anterior group there was a smaller decrease of QRS complex compared to the ...
The next part of the EKG wave is the QRS complex which features a small drop in voltage (Q) a large voltage peak (R) and another small drop in voltage (S). The QRS complex corresponds to the depolarization of the ventricles during ventricular systole. The atria also repolarize during ...

of containing a helix and circumferential wrap architectural configuration. Torrent Guasp's helical ventricular myocardial band (HVMB) defines this anatomy and its structure, and explains why the heart's six dynamic actions of narrowing, shortening, lengthening, widening, twisting, and uncoiling happen...
the ECG would reveal some P waves not followed by a QRS complex, while others would appear normal. In the third-degree or complete block, there is no correlation between atrial activity (the P wave) and ventricular activity (the QRS complex). Even in the event of a total SA block, the...

The T wave represents the repolarization of the ventricles. Electrical activity generated by the repolarization of the atria is concealed by the QRS complex. Figure 1. Different periods of the cardiac cycle: (a) electrocardiogram, (b) heart sounds, (c) valves, (d) pressure, and (e) volume...
