Ventricular Dysfunction: Tachycardia induced Cardiomyopathy

Tachycardia induced cardiomyopathy (TIC) is defined as atrial or ventricular dysfunction as a result of prolonged elevated heart rate that is reversible upon control of the arrhythmia. There may be no underlying structural heart disease primarily responsible for the cardiac dysfunction. We present some examples of arrhythmias causing TIC and the resolution of the ventricular dysfunction following their appropriate management. Included in the review are also the pathophysiology, clinical spectrum, diagnosis and appropriate management of the condition.
