T波的产生机理目前了解得尚不够,大致知道与心肌代谢过程有着密切关系,因此T波容易受各种生理、病理、物理、神经体液及药物等因素影响而发生改变。临床心电图实际工作中偶而可见巨大倒置的T波,T波所占的面积比QRS波大得多,Q-T间期延长,Q-T间期的延长是由于T波宽大所致,
T wave generation mechanism is not enough understanding of the current, generally know and myocardial metabolic processes are closely related, so T wave susceptible to a variety of physiological, pathological, physical, neuroendocrine fluids and drugs and other factors change. In clinical practice, electrocardiogram occasionally shows a huge inversion of T wave, the area occupied by T wave is much larger than that of QRS wave, the Q-T interval is prolonged, and the extension of Q-T interval is due to the wide T wave.
