摘要: Background— Tachycardia-induced cardiomyopathy is a reversible cause of heart failure. We hypothesized that although left ventricular ejection fraction measurements normalize after rate or rhythm control in patients with tachycardia-induced cardiomyopathy, recurrent tachycardia may have abrupt and deleterious consequences. Methods Results— Patients developed over years were evaluated treated. Tachycardia episodes outcomes assessed. Twenty-four identified. All had NYHA functional class III failure greater on presentation. One third transplant candidates. There 17 men 7 women mean age 46±16 0.26±0.09 at the index visit. The was atrial fibrillation (n=13), flutter (n=4), (n=3), idiopathic (n=1), permanent junctional reciprocating (n=2), bigeminal prematur...
