Because the normal ventricular conduction system (His ... Because the electrical activation originates at or near the AV node, the P wave is frequently not seen; it can be buried within the ...

The ECG findings presented as normal in athletes were established by an international ... 6,11–14 A junctional or nodal rhythm occurs when the QRS rate is faster than the resting P wave or sinus rate ...

Alternatively, if the PR interval is normal and the QRS duration is ... requires three different P wave morphologies in one ECG with a QRS complex rate of > 100. Wandering atrial pacemaker ...

These ECG voltage attenuations are of extracardiac mechanism, and impact the amplitude of QRS complexes, P-waves, and T-waves, occasionally resulting also in shortening of the QRS complex and QT ...

These lines are comprised of three main parts: In normal sinus rhythm, the P-P interval (the time between consecutive P waves) is the same throughout the ECG. Also, the heart rate (how fast the ...

The regular arrhythmia occurring at the beginning of the electrocardiogram was ... There is no associated P wave, although an independent normal P wave may precede, be within or follow the VPC.

In addition to changes in the ECG caused by disease, there are a variety of atypical ECG patterns, often called 'normal variants ... and repolarization (T wave), corresponding to the ST segment ...
