Cardiac resynchronization therapy improves heart rate profile and heart rate variability of patients with moderate to severe heart failure.
OBJECTIVES This study sought to report long-term changes of cardiac autonomic control by continuous, device-based monitoring of the standard deviation of the averages of intrinsic intervals in the 288 five-min segments of a day (SDANN) and of heart rate (HR) profile in heart failure (HF) patients treated with cardiac resynchronization therapy (CRT). BACKGROUND Data on long-term changes of tim...
متن کاملCardiac resynchronization therapy improves heart rate variability in patients with symptomatic heart failure.
BACKGROUND Cardiac resynchronization therapy (CRT) using biventricular pacing improves symptoms and functional capacity in patients with moderate to severe heart failure. The present study examined whether an improvement in ventricular performance from resynchronization therapy changes the autonomic control of heart rate. METHODS AND RESULTS Heart rate variability (HRV) was examined in 50 pat...
متن کاملEffect of age on long-term heart rate variability.
OBJECTIVE Previous studies on short-term time series of heart rage suggest an inverse relationship between age and spectral powers of heart rate variability in various frequency bands. In this study, we examined the relationship between age (6-61 years) and long-term heart rate variability. METHODS We obtained 24-h Holter ECG in 33 healthy human subjects (11 children and 22 adults). The heart...
متن کاملتغییرپذیری ضربان قلب Heart rate variability))
Abstract Many studies have been conducted on heart rate variability. Variability in the heart signal of two sequential beats is called heart rate variability (HRV). Short- and long- term variability reflects autonomic nervous system function, so that increased or decreased heart rate variability (HRV) is an indicator of human health. So, the analysis of these changes can predict sudden death...
