Tachycardia-Induced Heart Failure
Chronic supraventricular tachycardia (SVT) results in left ventricular (LV) dilatation and dysfunction. However, the underlying mechanisms responsible for LV failure in this setting are not known. LV force production is dependent on the coupling of myocytes to the extracellular matrix, which is mediated through the basement membrane. This study was designed to determine whether alterations in m...
متن کاملTachycardia-induced heart failure.
Heart failure associated with tachyarrhythmias can very often be reversed by dealing with the underlying tachyarrhythmia. Typically characterized by left ventricular dilation and subsequent systolic dysfunction, this disorder can be caused by both atrial and ventricular arrhythmias, most commonly chronic atrial fibrillation. Whereas for most cardiomyopathies there is little that can be done to ...
متن کاملIntrinsic cardiac nervous system in tachycardia induced heart failure.
The purpose of this study was to test the hypothesis that early-stage heart failure differentially affects the intrinsic cardiac nervous system's capacity to regulate cardiac function. After 2 wk of rapid ventricular pacing in nine anesthetized canines, cardiac and right atrial neuronal function were evaluated in situ in response to enhanced cardiac sensory inputs, stimulation of extracardiac a...

Objective: To test the hypothesis that early stage heart failure differentially affects the intrinsic cardiac nervous system’s capacity to regulate cardiac function. Methods: Following 2 wks of rapid ventricular pacing, in 9 anesthetized canines, cardiac and right atrial neuronal function were evaluated in situ in response to enhanced cardiac sensory inputs, stimulation of extracardiac autonomi...
متن کاملHeart failure and sudden death in patients with tachycardia-induced cardiomyopathy and recurrent tachycardia.
BACKGROUND Tachycardia-induced cardiomyopathy is a reversible cause of heart failure. We hypothesized that although left ventricular ejection fraction measurements normalize after heart rate or rhythm control in patients with tachycardia-induced cardiomyopathy, recurrent tachycardia may have abrupt and deleterious consequences. METHODS AND RESULTS Patients with tachycardia-induced cardiomyopa...
