目的探讨各种原因所导致的电张调整性T波改变的心电学特征。方法回复2010-2012年在本院存档的70例电张调整性T波改变,包括右心室心尖部起搏的电张调整性T波改变40例,室性心动过速的电张调整性T波改变12例,室上性心动过速并且伴室内差异性传导8例,预激综合征10例,根据具体情况进行12导联常规心电图记录,并随访观察直到T波恢复到正常水平为止。结果上述四种情况都可能引起电张调整性T波改变,并且每种情况都不相同:右心室心尖部起搏组胸前导联所引起的T波改变最为明显,室性心动过速导致T波改变也是存在的,室上性心动过速所引起的T波改变特别广泛,甚至会引起12导联同时出现,预激综合征虽未出现导联,但持续时间相对较长。结论通过电张调整性T波改变的不同特征进行诊断,可以减少不必要的检查,还可以减少一定程度的误诊,值得推广应用。
Objective To investigate the changes of electrocardiogram (T wave) caused by various reasons. Methods A total of 70 T-wave changes recorded in our hospital from 2010 to 2012 were retrospectively analyzed. T-wave changes of T-wave in 40 patients with right atrial apices, right ventricular tachycardia T Wave changes in 12 cases, supraventricular tachycardia with 8 cases of differential conduction indoors, pre-excitation syndrome in 10 cases, according to the specific circumstances of the 12 lead routine ECG records and follow-up observation until the T wave returned to normal levels so far. RESULTS All four of the above conditions were likely to cause T-wave changes in electrical modulation, and in each case were different: the T-wave changes caused by the thoracic aorta in the right ventricular apical pacing group were most pronounced and ventricular tachycardia resulted T wave changes also exist, T wave caused by supraventricular tachycardia changes particularly widely, and even lead to 12 leads appear at the same time, although there is no lead pre-excitation syndrome, but the duration is relatively long. Conclusions It is worth to popularize that the diagnosis of different characteristics of T wave changes can reduce unnecessary examination and reduce some misdiagnosis.
