加速的室性节律在成人中多有报告,常见于心肌梗塞、其它心脏病或洋地黄中毒的患者中,而在无心脏病的人中则罕见。过去仅见报告过1例小儿患者。本文报告4例患儿均为男孩,年龄各为13、11、6和14岁。前3例均无明显症状,在常规体检中被发现。通过X线胸片检查(3例)、超声心动图检查(2例)、心导管检查和心血管造影(2例),未发现器质性心脏病。心电图检查可见数段加速的室性节律,并能为增快的窦性心率或心房起搏所抑制。其中1例(例3)还可见到室性二联律,早搏的QRS波形态与加速的室性节律的QRS波相同,电生理研究证实心律失常
Acceleration of ventricular rhythms has been reported in adults, common in patients with myocardial infarction, other heart disease, or digitalis poisoning, but rare in those without heart disease. In the past only seen in 1 case of pediatric patients. This article reports 4 children were all boys, aged 13, 11, 6 and 14 years old. The first three cases were no obvious symptoms, was found in the routine physical examination. Through X-ray examination (3 cases), echocardiography (2 cases), cardiac catheterization and cardiovascular imaging (2 cases), no organic heart disease was found. Electrocardiographic examination revealed several accelerated ventricular rhythms and was suppressed by increased sinus rhythm or atrial pacing. One case (3) also showed ventricular bigeminy, QRS waveform of premature beat was the same as QRS wave of accelerated ventricular rhythm, electrophysiological studies confirmed arrhythmia
