摘要
目的探讨各种原因所致电张调整性T波改变的心电学特征.方法对64例电张调整性T波改变分右心室心尖部起搏32例、室性心动过速（VT）11例、室上性心动过速（PSVT）伴室内差异性传导10例、预激综合征11例四组,根据情况进行12导联常规心电图记录、随访、观察直至T波恢复正常为止,并进行分析.结果产生电张调整性T波的心室异常除极顺序呈聚集性,电张调整性T波改变在下壁（Ⅱ、Ⅲ、aVF）导联中4组均存在.此外,①右心室心尖部起搏组胸前导联亦广泛存在,T波倒置最深常分布在V3～V4导联.倒置的T波最深深度较其他三组深（均P〈0.01）.②VT组左胸导联亦存在,T波倒置最深的导联常分布在V4～V5.③PSVT组分布导联特别广泛,部分甚至12导联同时出现④预激综合征组分布最窄,其它导联均未出现.但其持续时间较其他三组长（P〈0.01）.结论根据各种原因所致电张调整性T波改变的心电学特征可以作出电张调整性T波的诊断.从而避免不必要的特殊检查,减少临床误诊、误治.
Aim To investigate electrocardiographic characteristics of pathogency electrotonie modulated T wave caused by various reasons. Methods Sixty-four cases concerning electrotonic modulated T wave were divided into four groups ：32 cases after the right ventricular apical pacing, 11 cases after the ventricular tachycardica terminated, 10 cases after the supraventricular aberrant ventricular condition and 11 cases after Wolff-Parkinson-White syndrome （WPW）. Based on different circumstances, 12-lead routine electrocardiogram （ECG） was recorded,interviewed,observed and analysed until T wave resumes the normal track. Results Abnormal depolarization order generating electrotonic modulated T wave presents collective. Electrotonic modulated T wave changes of four groups exist in inferior wall lead （ Ⅱ ,Ⅲ,aVF in leads）. Besides, the following four conclusions were made. ①The right ventricular pericardial leads pericardial were also widespread. The deepest distribution of T wave inversion is in lead V3 - V4. The T wave inversion is significantly deeper than those ventricular tachycardic groups, the supraventricular tachycardica groups and WoUt-Parkinson-White syndrome groups （ P 〈 0.01 ） ② The left pericardial leads of ventricular tachycardica group also exist. The deepest distribution of the T wave inversion in lead is between V4 - V5③The supraventricular tachycardica group, distribution of lead were especially widespread, and part of them even 12 leads appear at the same time. ④The Wolff-Parkinson-White syndrome group distribution of lead is the narrowest, and other leads never appear. But they last significantly longer than the right ventricular apical pacing group, ventricular tachycardic group and the superaventricular tachycardica group. Conclusion According to electrocardiographic characteristics of pathogency electrotonic modulated T wave caused by various reasons, diagnosis can be made so as to avoid unnecessary particular examination and reduce wrong diagnosis and treatment.
