1 临床资料1990年2月-1991年7月作者通过体检及门诊发现马拉松长跑、短跑、武术等耐力及强烈性运动员左心室肥厚者10例,其中男性8例,女性2例,年龄21～25岁均经心电图确诊。无临床证状。心电图为左心室肥厚,窦性心动过缓。2 讨论经过长期耐力运动如马拉松长跑等及剧烈性运动如拳击、武术等运动员,可较未经受过此种运动训练者心率缓慢。当运动时,心收缩力增强,心脏频率上升较少;运动量继续加大时心输出量和心动周期
1 Clinical data February 1990-July 1991 the author found through physical examination and out-patient marathon long-distance running, dash, martial arts and other endurance and strong athletes with left ventricular hypertrophy in 10 cases, including 8 males and 2 females, aged 21 to 25 The average age confirmed by ECG. No clinical evidence. ECG left ventricular hypertrophy, sinus bradycardia. 2 Discussion After long-term endurance sports such as marathon long-distance running and strenuous exercise such as boxing, martial arts and other athletes, compared with those who have not exercised such slow heart rate training. When exercise, cardiac contractility increased, the heart rate increased less; exercise continue to increase when cardiac output and cardiac cycle
