Introduction:

Electrocardiogram (ECG) is used to monitor the heart rate of the patients as it is a diagnostic machine. The heartbeat is recorded in the form of wave components, such as P, Q, R, S, T, and U. Doctors interpret the ECG through a systemic approach.

Explanation

Premature ventricular contraction (PVC) is also called ventricular premature beats. When extra heartbeat occurs in the ventricles part of the heart due to certain electrical activity, it is detected by the absent P wave and T wave positioned opposite to the QRS complex.

QRS duration: Duration is irregular and long and is less than 0.12 seconds.

QT duration: Duration >0.12 seconds.

Ventricular rate and rhythm: Rate and rhythm are irregular and more than 100bpm...
