A combination of the Q wave, R wave and S wave, the “QRS complex” represents ventricular depolarization. This term can be confusing, as not all ECG leads contain all three of these waves ...

There are two different rates that can be determined on an ECG. The atrial rate is indicated by the frequency of the P waves. The ventricular rate is indicated by the frequency of the QRS complexes.

A mobile application that can receive data via Bluetooth and display an ECG graph, heartbeat per minute and R to R interval is also developed using MIT App Inventor 2 IDE. This paper explains in ...

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 ...

Objective: Precordial ECGs reveal significant intrasubject variability due to the inexact employment of the recommended V 1-V 6 chest landmarks. Also, as per the Einthoven law, the six limb leads ...
