Abstract: During the month of Ramadan Muslims worldwide fast daily from dawn to dusk. They refrain from consuming food, drinking a liquid, and smoking. In this paper, a pilot study of the effect of fasting on blood pressure pulse transient time (PTT) of healthy subjects is presented. Blood pressure wave transient time referenced to ECG R-wave was measured for a group of seven healthy male subjects one time, in Ramadan during fasting and one time after the month of Ramadan. The Systolic blood pressures, heart rates, and the heights of all recruited subjects were recorded. An ECG and photoplethysmography (PPG) computer-based systems were designed and used in this research. ECG and PPG signals are preprocessed by Whittaker’s smoother and their peaks are detected by Pan Tompkins peak detection technique. The pulse transient time was measured at the right and left fingers and toes. After analyzing the results, a paired two samples for means at P<0.05, showed that the pulse transient time (PTT) differ significantly in fasting except for the right fingers, where the test was not significant. The coefficients (msec/mmHg) of PTT versus systolic pressure is higher in fasting than in non-fasting conditions with p<0.005
