On average, heart rate, or pulse, bolted from about 70 beats per minute up to 100. The range, however, was wide. Some subjects’ pulse climbed up to 150, while others’ got no higher than 95. Blood pressure also jumped from values of about 110/70 to an average of 145/100. Heart rate and blood pressure fell as rapidly as they rose, already beginning to taper off between the 2- and 5-minute recordings.
