Depending upon the site of origin of premature beat it is classifid as—

I. Supraventricular premature beat / atrial or nodal

II. Ventricular premature beat.

Compensatory pause

It is defied as the pause between the premature beat and the next sinus beat.
Compensatory pause can be of two types they are:

1. Complete compensatory pause

2. Incomplete compensatory pause.

Complete compensatory pause: If the compensation occurs exactly for the missed beat

and the third sinus beat occurs exactly where it would otherwise occur, then it is a
complete compensatory pause.

Incomplete compensatory pause:

If the beat following the premature beat occurs before the next expected beat, then it is
incomplete compensatory pause.
