Heart Rate Recovery in Patients With Hypertrophic Cardiomyopathy

open access: yesThe American Journal of Cardiology, 2014
Recovery in heart rate (HR) after exercise is a measure of autonomic function and a prognostic indicator in cardiovascular disease. The aim of this study was to characterize heart rate recovery (HRR) and to determine its relation to cardiac function and morphology in patients with hypertrophic cardiomyopathy (HC).
