Idioventricular Rhythm
| Rate | 20 to 40 beats per minute |
| P wave | Absent |
| QRS | Widened |
| Conduction | Failure of primary pacemaker |
| Rhythm | Regular |
Absent P wave
Widened QRS > 0.12 sec.
Also called " dying heart" rhythm
Pacemaker will most likely be needed to re-establish a normal heart rate.
Causes:
- Myocardial Infarction
- Pacemaker Failure
- Metabolic imbalance
- Myoardial Ischemia
Treatment goals include measures to improve cardiac output and establish a normal rhythm and rate.
Options include:
- Atropine
- Pacing
Caution: Suppressing the ventricular rhythm is contraindicated because that rhythm protects the heart from complete standstill.
