患者男性、50岁,患冠心病6年。1987年6月22日左胸痛伴心慌气短,当日ECG诊断:逸搏-早搏-夺获形成的三联律。心电图V_1导联(附图,见第102页):每3个心室波群为一组,被最长的R-R间期1.39s分开。每组以其前后无相关P波的交界性逸搏为首,心室波群呈rS,T波直立,在交界性逸搏内有与之干扰的窦性P波,正负双相的窦性P的负相位于逸搏QRS末端。每组的第2个心搏提前出现,呈rS,其前有直立的P波,P-R间期0.07s,T波倒置,R-R间期0.69s,此为交界性早搏。每组的第3个心
Male patient, 50 years old, suffering from coronary heart disease for 6 years. June 22, 1987 left chest pain with palpitation shortness of breath, the day ECG diagnosis: escape stroke - premature beats - won the formation of the triple law. ECG lead V_1 (with photos, see page 102): Each group of three ventricular waves as a group, was separated by the longest R-R interval 1.39s. Each group with its before and after the absence of relevant P wave junctional escape led to the first, the ventricular wave group was rS, T wave upright, in the junctional esophageal disturbance with sinus P wave, positive and negative biphasic sinus P The negative phase is located at the QRS end of esophageal stroke. The second heartbeat of each group appeared in advance, was rS, in front of an upright P wave, P-R interval 0.07s, T wave inversion, R-R interval 0.69s, this is borderline premature beats. The third heart of each group
