This study compared heart rate, blood pressure, and electrocardiographic response of post myocardial infarction males taking either vasodilator and beta blocker or just beta blocker medications, and a control, to different water temperatures in a hot tub. Twentysix adult males were observed. Each subject engaged in exercise, then sat in a hot tub for 12 minutes. Each subject repeated this procedure three times, once at each water temperature (36.6°, 38.3°, and 40°C).
The data during immersion indicated: (a) heart rate was affected by increased temperature and duration of exposure; (b) blood pressure was affected by length of exposure; (c) frequency of arrhythmias was influenced by group differences; and (d) immediately following immersion, heart rate was influenced by temperature, blood pressure was influenced by interaction of temperature and group differences. It was concluded that immersion in water up to 40°C by post myocardial infarction males taking vasodilator and/or beta blocker medications should not be restricted.
