Purpose: Medically supervised exercise programs (MSEPs) are equally recommended for men and women with cardiovascular disease (CVD). Aware of the lower CVD mortality in women, we hypothesized that among patients attending a MSEP, women would also have better survival.
Methods: Data from men and women, who were enrolled in a MSEP between 1994 and 2018, were retrospectively analyzed.
Background: Physiological reflexes modulated primarily by the vagus nerve allow the heart to decelerate and accelerate rapidly after a deep inspiration followed by rapid movement of the limbs. This is the physiological and pharmacologically validated basis for the 4-s exercise test (4sET) used to assess the vagal modulation of cardiac chronotropism.
Objective: To present reference data for 4sET in healthy adults.
Objective: To determine the viability of using a conventional electrocardiogram (ECG) tracing for assessment of CVA.
Methods: We retrospectively analyzed 1395 individuals (995 males), aged 46 +/- 17.2 years (mean +/- standard deviation) with conventional ECG tracings to measure the delta RR (which represents the difference in milliseconds (ms) between the greatest and smallest RR interval) and results of a second autonomic parasympathetic evaluation, the 4-second exercise test (T4s), that quantifies CVA by the cardiac vagal index (CVI).
