Abstract:
Water immersion-induced skin wrinkling (WISW) is dependent on intact peripheral sympathetic function. WISW was hypothesized to reflect autonomic function in subjects without peripheral neuropathy. We prospectively studied 70 healthy subjects (aged 31 ± 8 years, 63% females) without cardiovascular risk factors or neurological disease. All subjects underwent short-term heart rate variability (HRV) studies. Time and frequency domain variables were derived including the HRV index. WISW was graded using a previously validated scale of 1-4 of which 18.6% of subjects exhibited grade 1 (minimal) WISW and 35.7% had grade 2 WISW. On multivariate analysis using the HRV index, WISW was independently related to height and the HRV index. We conclude that WISW is related to central autonomic function.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...
01:31Regulation of Heart Rates
The SNS increases heart rate through the release of norepinephrine and epinephrine, which act on beta-1 adrenergic receptors in the heart. This action increases the rate of depolarization in the sinoatrial (SA) node, the heart's...
01:19Cardiac Output I:Effect of Heart Rate on Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart rate...
