Previous studies investigating autonomic cardiovascular control in elderly persons usually
included analysis of RR interval but not of blood pressure variability.“Physiological” blood …

Key points Rodent models of intrauterine growth restriction (IUGR) successfully identify
mechanisms that can lead to short‐term and long‐term detrimental cardiomyopathies but …

We examined the relationship between age-associated lusitropic impairment, heart rate, and
Ca2+-handling proteins and assessed the efficacy of increasing left ventricular (LV) …

Aims This study investigated ventricular electrophysiological characteristics and the
correlation between these parameters and heart rate variability (HRV) and baroreflex …

Objectives. The effects of increasing heart rate on left ventricular contraction and relaxation
were examined in conscious dogs with tachycardia-induced heart failure under …

The analysis of beating rate provides information on the modulatory action of the autonomic
nervous system on the heart, which mediates adjustments of cardiac function to meet …

Aging impairs sympathetic and parasympathetic cardiac control. Although the reduced
sympathetic responses are known to depend on an age-related cardiac beta-adrenoceptor …

Depressed heart rate variability (HRV) after a myocardial infarction is associated with
increased mortality. This is thought to be due to reduced parasympathetic activity and …

There is strong evidence that autonomic imbalance plays an important role in progression of
heart failure. Analysis of heart rate variability (HRV) has achieved substantial acceptance as …

A decrease in maximal exercise heart rate (HRmax) is a key contributor to reductions in
aerobic exercise capacity with aging. However, the mechanisms involved are incompletely …
