| Anger and other strong emotions can
trigger potentially deadly heart rhythms in certain vulnerable people. Previous studies have shown that earthquakes, war or (62) the loss of a World Cup Soccer match can increase (63) of death from a sudden cessation(停止) of heartbeat, (64) the heart stops circulating blood. "It’s (65) been shown in all different ways that when you put a whole (66) under a stressor that sudden death will increase," said Dr. Rachel Lampert, whose study (67) in the Journal of the American College of Cardiology. "Our study starts to look (68) how this really affects the electrical system of the heart," Lampert said. She and colleagues studied 62 patients with heart (69) and implantable heart defibrillators (电震发生器) or ICDs that can (70) dangerous heart rhythms or arrhythmias(心律失常) and deliver an electrical shock to restore a normal heart (71) . "These were people we know already had some (72) to arrhythmia," Lampert said in a telephone interview. Patients in the study took part in an exercise in which they (73) a recent angry episode (74) Lampert’s team did a test called T-Wave Alternans that (75) electrical instability in the heart. Lampert said the team specifically asked questions to get people to relive the angry (76) . "We found in the lab setting that yes, anger did increase this electrical instability in these patients," she said. "The people who had the (77) anger-induced electrical instability were 10 times more (78) than everyone else to have an arrhythmia in follow-up," she said. Lampert said the study (79) that anger can be deadly, at least for people who are already vulnerable to this type of electrical disturbance in the heart. "It says yes, (80) really does impact the heart’s electrical system in very (81) ways that can lead to sudden death," she said. |
