Key result
Controlling the heart rate in patients with tachycardia-induced cardiomyopathy can result in marked improvement or complete restoration of systolic function.
Why the study?
Does heart rate control improve systolic function in patients with tachycardia-induced cardiomyopathy?
Does heart rate control improve systolic function in patients with tachycardia-induced cardiomyopathy?
Recognizing tachycardia-induced cardiomyopathy is crucial as controlling the heart rate can reverse myocardial dysfunction.

Warrants consideration of heart rate control in suspected tachycardia-induced cardiomyopathy; leaves open need for prospective trials to guide adoption.
Tachycardia-induced cardiomyopathy is caused by sustained rapid ventricular rates and is one of the well-known forms of reversible myocardial dysfunction. The diagnosis is usually made retrospectively after marked improvement in systolic function is noted following control of the heart rate. Physicians should be aware that patients with seemingly idiopathic systolic dysfunction may have tachycardia-induced cardiomyopathy and that controlling the heart rate may result in improvement or even complete restoration of systolic function.

Lishmanov et al. (2010) conducted a review in Tachycardia-induced cardiomyopathy. Heart rate control was evaluated on Improvement or complete restoration of systolic function. Controlling the heart rate in patients with tachycardia-induced cardiomyopathy can result in marked improvement or complete restoration of systolic function.
