The P wave in lead V1 was always positive for left atria origin and always negative for RAA origin. P waves of high CT-originated AT always showed positive-negative (biphasic) variation in lead V1.

The P-wave feature of CT-originated AT is already well described and therefore its localization from the ECG is not controversial. [1, 10, 14] The P-wave feature of AT arising from superior TA was ...

From heatwaves to green waves: U.P plans mega plantation drive By Gaurav Saigal, Lucknow Published on: Jun 14, 2025 08:04 AM IST ...

At a time when the Holocaust is falling out of living memory, we are leaving young people to their own devices, quite literally, to separate fact from fixation.

A total of 88 stroke patients and 91 control subjects were excluded because of absence of native P-waves on the ECG (eg, atrial fibrillation, pacemaker rhythm), leaving 146 stroke patients and 195 ...

Cardiac output (CO) and stroke volume (SV) are physiological variables that reflect the efficiency of the heart pumping blood to all tissues of the body. Access to measure cardiac output by ...

Specific supraventricular tachycardia (SVT) classification using surface ECG is considered a challenging task, since the atrial electrical activity (AEA) waves, which are a crucial element for ...

Likely, in some cases the inclusion of U-wave or the final part of a biphasic T-waves in the P-wave measurement may lead to a P-wave duration overestimation. This fact serves to remind the realm on ...

With notched or biphasic T waves or superimposed U wave, the end of the entire T-wave complex should be considered the end of the QT interval. If a U wave is discrete, that is, occurring after the T ...
