| 摘 要： | 从实验性力量练习后即刻采集的ＥＣＧ数据中发现，当人体经大力量负重蹲腿起后，Ｊ点下移（ｄｏｗｎｗａｒｄｄｉｓｐｌａｃｅｍｅｎｔｏｆＪｐｏｉｎｔ）、Ｓ－Ｔ段平直延长（Ｓ－Ｔｓｅｇｍｅｎｔｆｔａｔｓｔｒａｉｇｈｔｐｒｏｌｏｎｇａｔｉｏｎ）、大于５０％，和Ｑ－Ｔ比值，以及Ｑ－Ｔｃ都增大，作者认为是练习后心肌缺血缺氧，电解质紊乱细胞内Ｋ＋浓度升高，血钙过低、除极波受阻引起损伤电位以及心内膜缺血部位的Ｂａｙｌｉｓｓ效应所造成。

| Abstract: | According to the data which has been got immediately after strength exercise, we found that J point is displaced downed, S-T sesegment flatstraight is prolonged, Q-X / Q-T is more than 50%, and the rates of Q-T / R-R, Q-T and Q-Tc are all increased. The author thinks that the reason is that cardiac muscle is short of blood and oxygen, electrolyte is isin disorder the consistency of K goes up, blood Ca is too low, and Bayliss effect. |
