Multifocal atrial tachycardia (MAT) requires three different P wave morphologies in one ECG with a QRS complex rate of > 100. Wandering atrial pacemaker (WAP) requires three different P wave ...

The waves on an ECG include the P wave, Q wave, R wave, S wave, T wave and U wave. Interval: The time between two specific ECG events. The intervals commonly measured on an ECG include the PR ...

Multiple other ECG traits have also emerged as potential predictors of stroke, namely cardiac electrical/structural remodeling – Q wave, QRS/QT duration, bundle blocks, P wave duration/amplitude ...
