Overview
Tachycardia induced cardiomyopathy is a weakening of the myocardium (the muscle of the heart) that is due to prolonged periods of a fast heart rate.
Risk Factors
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.
==Prognosis==D
epending upon the duration of the tachycardia, the condition is either completely or partially reversible.
Treatment
The primary treatment for a tachycardia induced cardiomyopathy is correct the underlying tachycardia. Supportive agents such as beta blockers and ACE inhibitors / angiotensin receptor blockers are of benefit to try to prevent remodeling of the left ventricle.
If the tachycardia can be abolished, the heart muscle can recover after some time.[1]
Not only is there a need to control the tachycardia that is responsible for causing tachycardia induced cardiomyopathy, but also treating underlying conditions that cause tachycardia. For instance, treatment of hyperthyroidism can also lead to reversal of tachycardia induced cardiomyopathy.
