摘　　要：目的探讨致心律失常性右心室发育不良(ARVD)的心电图演变过程。方法对1例ARVD患者2002年与2011年的心电图表现进行对照比较,结合心脏彩色超声检查,分析病程进展对心电图表现的影响。结果随着右心室内径增大和肺动脉压增加,QRS时限逐渐增宽;各导联QRS终末变为粗钝并伴有切迹,V1导联出现明显ε波;右胸、中胸导联T波负向程度显著加重,下壁导联T波由正向变为负向。患者始终伴有多源性室性心动过速。结论 QRS时限在ARVD早期未必延长,而随着病程的发展有逐渐增宽的趋势,且下壁导联的T波也可能受到累及。ARVD可伴有多源性室性心动过速。Objective To explore the changes of electrocardiogram （ECG） of the arrhythmic right ventricular dysplasia （ARVD） . Methods The effects of the development of ARVD on ECG were analyzed by comparing ECGs of 2002 and 2011 with color ultrasonography of a patient with ARVD. Results With the increase of internal diameter of right ventricle and pulmonary arterial pressure, the Q RS interval prolonged gradually; the end of Q RS became slurring and notching; V1 lead showed e wave; the degree of T wave inversion became serious from V1 to V4 leads; and the T waves of Ⅱ , Ⅲ and aVF leads also inversed. The patient showed multifocal ventricular tachycardia. Conclusion The Q RS interval may not prolong at the early stage of ARVD, but with the development of the disease, it will prolong gradually and T waves of Ⅱ,Ⅲ and aVF leads may inverse. The multifocal ventricular tachycardia may accompany ARVD.
