EFFECT OF 30°AND 60° HEAD UP TILT ON CARDIOVASCULAR RESPONSES IN NORMOTENSIVE AND HYPERTENSIVE INDIVIDUALS
Journal Title: International Journal of Medical Research & Health Sciences (IJMRHS) - Year 2014, Vol 3, Issue 1
Abstract
Since 50 years, head up tilt table testing is being used by physiologists and physicians for different purposes. Many investigators have studied the effect of head up tilt at a specific angle on cardiovascular and autonomic functions in healthy individuals and reported usefulness of HUT in assessing the integrity of cardiovascular and autonomic functions. In present study effect of 30° and 60° head up tilt is studied on cardiovascular parameters (systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse pressure (PP), mean arterial blood pressure (MAP), heart rate/min (HR), rate pressure product (RPP)) in normotensive and hypertensive individuals. METHODS: Effect of 30° and 60° head up tilt on cardiovascular parameters was studied in normotensive (n=50) and hypertensive individuals (n=50) aged 15-70 years. Blood pressure and heart rate were determined by using electronic blood pressure apparatus. RESULTS: 30° and 60° HUT produced decrease in SBP, PP, MAP and increase in DBP, HR, RPP in both groups. The results were significant at selected different time intervals. The changes produced by 60° HUT were more significant than 30° HUT. The changes produced in the hypertensive group were more prominent than normotensive group. In conclusion significant changes in HR and RPP in hypertensive individuals indicated more myocardial oxygen consumption and myocardial work at both angles of HUT.
