Why the study?
Tachycardiomyopathy is a potentially reversible cause of heart failure requiring a high index of suspicion, prompting this description of clinical profiles, treatment, and outcomes.

Hypothesis-generating for rate control in tachycardiomyopathy; prospective trials needed before practice change.
Does heart rate control therapy improve clinical symptoms and left ventricular ejection fraction in patients with tachycardiomyopathy?
In patients with tachycardiomyopathy, restoring normal heart rhythm or controlling heart rate leads to significant clinical improvement and recovery of left ventricular ejection fraction.
