This document describes two types of ventricular arrhythmias: idioventricular rhythm and asystole. Idioventricular rhythm is an escape rhythm produced by the ventricles at a rate of 20-40 beats per minute without P waves and with wide QRS complexes. Asystole is a flat line on the EKG indicating the absence of any electrical activity in the heart with a rate of 0 beats per minute and no P waves or QRS complexes.

1. Idioventricular Ventricular
Arrhythmias

2. Idioventricular Rhythm
 Ventricular rhythm produced as an
escape rhythm
 The heart is depolarized at the
inherent rate of the ventricles which
is 20-40bpm.

3. Idioventricular Rhythm
 No P wave seen
 Rhythm usually regular
 QRS complex will be wide
 Rate will be less than 40

4. Idioventricular Rhythm

5. Asystole
 Rhythm - Flat
 Rate - 0 Beats per minute
 QRS Duration - None
 P Wave - None
Straight line indicates absence of all
electrical activity

6. Asystole
 Confirm all leads are correctly
attached to patient
 Confirm that machine is functioning
properly
 Confirm rhythm in two different
leads

7. Asystole

8. Name that rhythm!!
