Aim of this study was to assess the effects of right lateral position of body on cardiovascular parameters. Systolic blood pressure, diastolic blood pressure and heart rate are the main cardiovascular parameters. A total of 100 healthy male subjects were chosen for the study. Systolic blood pressure, diastolic blood pressure and heart rate were recorded after 10 minutes of rest in supine position and right lateral position. Systolic blood pressure, diastolic blood pressure and heart rate were significantly lower in right lateral position than supine state. The results suggest higher vagal activity and lower sympathetic activity in right lateral position of the body.

Abstract


Aim of this study was to assess the effects of right lateral position of body on cardiovascular parameters. Systolic blood pressure, diastolic blood pressure and heart rate are the main cardiovascular parameters. A total of 100 healthy male subjects were chosen for the study. Systolic blood pressure, diastolic blood pressure and heart rate were recorded after 10 minutes of rest in supine position and right lateral position. Systolic blood pressure, diastolic blood pressure and heart rate were significantly lower in right lateral position than supine state. The results suggest higher vagal activity and lower sympathetic activity in right lateral position of the body.
