Based on the given diagram the approximate corresponding time of
the heartbeats are
1st: 1.9 seconds
2nd: 3 seconds (+1.1s)
3rs: 4.2 seconds (+1.2s)
4th: 5.8 seconds (+1.6s)
5th: 7 seconds (+1.2)
6th: 8.1 seconds (+1.1s)
7th: 9.5 seconds (+1.4s)
8th: 11 seconds (+1.5s)
9th: 12 seconds (+1s)
From the above observation, the average time taken between each
heart beat =
(1.1+1.2+1.6+1.2+1.1+1.4+1.5+1)/8 = 1.26
Therefore, the heart rate = 60/1.26 beats/minute
= 47.619 bpm.

Heart rate during laughter. Laughter is often called “the best medicine,” since studies have shown that laughter can reduce muscle tension and increase oxygenation of the blood. In the International Journal of Obesity (Jan. 2007), researchers at Vanderbilt University investigated the physiological changes that accompany laughter. Ninety subjects (18–34 years old) watched film clips designed to evoke laughter. During the laughing period, the researchers measured the heart rate (beats per minute) of each subject, with the following summary results: Mean...
