1.引言 长时期的训练对心脏的形态,功能和生物化学产生不同的效应,“运动员心脏”通常用来描述心脏对长期训练的适应性改变,1899年Henschen最早描述了“运动员心脏”的临床表现:窦性心动过缓,听诊可闻第三、第四心音,经常有收缩期来 1. INTRODUCTION Long-term training has different effects on the morphology, function and biochemistry of the heart. “Athlete’s heart” is usually used to describe the adaptive changes of the heart to long-term training. Henschen first described the “Athlete’s Heart” clinical Performance: Sinus bradycardia, auscultation can smell the third and fourth heart sounds, often have systolic
