Prognostic value of QT/RR slope in predicting mortality in patients with congestive heart failure.

abstract：BACKGROUND:Historically, individuals diagnosed with an inherited arrhythmia or cardiomyopathy have been advised to avoid participating in competitive sports. Consequently, these individuals may be more susceptible to weight gain and obesity. METHODS:A retrospective longitudinal chart review was performed for a populat...
