Abstract

Pulse transit time(PTT) is a simple, noninvasive measurement, defined as the time interval between two characteristic points - the R wave of the electrocardiogram(ECG) and peak of the peripheral pulse at finger. PTT is influenced by heart rate, breathing changes and the compliance of the arteries. In this paper, we measured PTT and heart rate from 10 normal healthy subjects during factitious breathing. Over the 10 subjects, the maximum change in PTT ranged from 3 to 18ms with a mean ± standard deviation of 12 ± 5.98ms, and that in the rate of heart beat was heart rate from 1 to 14 beats(6 ± 3.6 beat/min). We conclude that factitious breathing effect a change of PTT and heart rate.
