Accelerated Idioventricular Escape Rhythm

An Accelerated Idioventricular Escape Rhythm is bizarre phenomenon in which a ventricular escape rhythm (which is usually only between 30-40 beats per minute) is accelerated to up to 100 beats per minute, but is slower than ventricular tachycardia.

Accelerated Idioventricular Escape Rhythm ECG

Heart Rate: between 40 and 100 beats per minute.

Rhythm: essentially regular.

Pacemaker site: normally from an ectopic pacemaker site within the ventricles.

QRS Complex: abnormally wide (greater than .012 seconds in duration) and bizarre in appearance.

Accelerated Idioventricular Escape Rhythm Signs and Symptoms

These people will usually appear asymptomatic unless the rhythm degenerates to a straight ventricular escape rhythm or ventricular tachycardia.
