Abstract:

Objective: To determine the prevalence of orthostatic hypotension in our patient population by using Head Up Tilt Test (HUTT). Study Design: Descriptive cross-sectional study. Place and Duration of Study: Armed Forces Institute of Cardiology & National institute of heart diseases, from Jan 2019 to Jan 2020. Methodology: Head Up Tilt Test registry was used as a data collection tool which consisted of gender, age, symptoms, number of episodes, results, baseline blood pressure systolic, baseline blood pressure diastolic, mean blood pressure, baseline heart rate. All patients from age 20-80 undergoing Head Up Tilt Test examination were included while patients already diagnosed with orthostatic hypotension, vasovagal syncope, and cardiac myopathy were excluded from the study. Results: Total 1587 individuals were enrolled in study, I1216 (76.6%) were males and 371 (23.4%) were females. The mean age of the study population was 45.63 ± 19 years. The results determined 67.6 (4.2%) were negative, 7(0.4%) had Vasodepressive Response of vasovagal reflex, 1435 (90.4%) had positive type 1; while 1 (0.1%) had positive type 2; and 4 (0.3%) had positive type 3; 62 (3.9%) had mixed vasovagal reflex, 1 (0.1%) had late orthostatic response and 10 (0.6%) had orthostatic hypotension. Conclusion: Tilt-table testing is an effective method to diagnose orthostatic hypotension.
