Tachycardia induced cardiomyopathy

What is Tachycardia induced cardiomyopathy?

Tachycardia induced cardiomyopathy, also known as chronotropic cardiomyopathy and tachycardiomyopathy, is an impairment of the pumping efficiency of the myocardium (the muscle of the heart) due to prolonged periods of a fast heart rate or irregular heart rhythm. It was first described by Phillips and Levine in 1949. and can occur at any age.

The rate and duration of the elevation in heart rate necessary to cause a cardiomyopathy is unclear and is likely dependent on a number of unknown factors.
