Note. Reproduced with permission from the APA. HR = heart rate in beats per min; FPA = finger pulse amplitude in mv; PTF = pulse transmission time to the finger and PTE = pulse transmission time to the ear, each in msec; DBP = diastolic blood pressure and SBP = systolic blood pressure, each in mmHg. Asterices indicate changes significantly different form baseline measures by within-subject t-tests (df = 55).
