An Irregular Ventricular Tachycardia Resulting in Tachycardia Induced
Cardiomyopathy
Abstract
Introduction Ventricular tachycardias although they may be irregular at
the onset, after several seconds they organize into a stable cycle
length. Methods/Results We report a rare case of an “irregular
ventricular tachycardia” in which the oscillations in cycle length were
so pronounced that it was initially misdiagnosed as atrial fibrillation
with aberrant conduction. The initial pharmacological management and
detained electrophysiological study are presented. Conclusion An unusual
irregular ventricular tachycardia can originate from the moderator band
and result in a tachycardia induced cardiomyopathy
