Exergame has become widely popular and offers great levels of cognitive demands, thus may facilitate cognitive benefits. In addition, researchers have proposed that cardiac autonomic function, assessed via heart rate variability (HRV), is associated with cognitive executive function. However, few exergame training studies have investigated this relationship.

Purpose: Resting beat-to-beat blood pressure variability is a strong predictor of cardiovascular events and mortality. However, its underlying mechanisms remain incompletely understood. Given that the sympathetic nervous system plays a pivotal role in cardiovascular regulation, we hypothesized that alpha-1 adrenergic receptors (the main sympathetic receptor controlling peripheral vasoconstriction) may contribute to resting beat-to-beat blood pressure variability.

Comprehensive Centre for Stroke Care, Department of Neurology, Sree Chitra Tirunal Institute for Medical Sciences and Technology, Trivandrum, Kerala 695011, India. Electronic address:

Background: The QT interval in ECG is susceptible to autonomic fluctuations, a known occurrence in acute ischemic stroke (AIS). Previous research has highlighted QT interval changes between ischemic and haemorrhagic strokes. However, there is scarce literature on the differential effect of AIS subtypes on QT interval.
