临床资料患者男性,29岁,外科医生,因近日来常感心悸胸闷而入院。入院前后多次心电图检查皆有室性早搏,但体格检查、技术诊断和化验检查等皆未发现其他异常。临床拟诊心肌炎,经乙胺碘呋酮、慢心律、安定,GIK、能量合剂等治疗23天,复查心电图早搏消失后出院。心电图分析与诊断本文附图上下两行是V_1导联的连续记录。主导心律为窦性心律。畸形QRS往往与窦性的QRS交替出现,它与其前的窦性QRS之间的配对间期不等,其变量范围是0.72～1.08秒。畸形QRS之间的长间歇(R_(6-8))等于短间歇(R_(2-4),(10-12),(12-14))的两倍。畸形QRS往往发生在
Clinical information Male patient, 29 years old, surgeon, admitted to hospital because of palpitation chest tightness. Multiple ECG before and after admission are premature ventricular contractions, but physical examination, technical diagnosis and laboratory tests were found no other abnormalities. Clinical simulacrum myocarditis, by amiodarone, slow heart rate, stability, GIK, energy mixture and other treatment for 23 days, review ECG premature beats disappeared after discharge. ECG analysis and diagnosis The upper and lower lines of the figure in this document is a continuous record of the V_1 lead. Leading rhythm of sinus rhythm. The abnormal QRS often alternates with the QRS of sinus and the pairing interval between it and its former sinus QRS ranges from 0.72 to 1.08 seconds. Long breaks (R_ (6-8)) between malformed QRSs are equal to twice the short breaks (R_ (2-4), (10-12), (12-14)). Abnormal QRS often occurs
