在运动员的心电图上,低电压比较常见。研究证明,心电图标准导联中QRS波群向上最高波不超过5mm,是确定为低电压心电图比较准确的方法。 低电压心电图在各项目的运动员中均可见到,但多见于举重、摔跤、体操、射箭、帆船和摩托车运动员。形成的原因主要是训练和比赛时运动负荷过大、训练时间太长,大量材料证明,运动员中67％的低电压心电图是正常变异。多数是与运动训练有关的心外原因造成的。尤其是骨骼肌的过度发达,由心电位改变形成的低电压心电图为数不多。
In the athlete’s ECG, low voltage is more common. Studies have shown that the standard ECG lead QRS wave group up to the maximum wave does not exceed 5mm, is determined as low-voltage ECG more accurate method. Low-voltage electrocardiogram can be seen in all athletes, but more common in weightlifting, wrestling, gymnastics, archery, sailing and motorcycle athletes. The main reason for the formation of training and competition is too much exercise load, training time is too long, a large number of materials that 67% of athletes, low-voltage ECG is a normal mutation. Most are related to exercise training caused by extra-cardiac causes. In particular, excessive development of skeletal muscle, ECG changes from the formation of low-voltage ECG is one of the few.
