患者男性,20岁,临床诊断:病毒性心肌炎。附图为Ⅱ及 V_1连续记录。窦性 P 波不规则出现,最短的 P-P 间期为1.09s,最长 P-P2.07s,长的 P-P 间期为明显窦性心律不齐或室早逆行重整所致,平均心房率约49次/min。V_1的 ORS波呈3种不同形态:(1)V_1上行的 R_(1、6、11)及 V_1下行的 R_(1、5、9、13)为 rS 型,时间0.07s,其前无 P 波或 P-R 明显小于0.12s,QRS 均在1.30s 后发生,为房室交界性逸博。(2)V_1上行的 R_(3、5、8、10、12)及 V_1下行的 R_(3、7、11)仍为 rS 型,但 S 波振幅明显小于前者,而 r 波反大于前者,时间0.07s,其前均有 P 波,P-R 大于0.12s,为窦性心律。(3),V_1上行的 R_(2、4、7、9、13)及 V_1下行的 R_(2、4、6、8、10、12)亦为 rS
Male patient, 20 years old, clinical diagnosis: viral myocarditis. The picture shows Ⅱ and V_1 continuous record. Sinus P wave irregularities, the shortest PP interval was 1.09s, the longest P-P2.07s, long PP interval was significantly sinus arrhythmia or premature ventricular retrograde reformation due to the average atrial rate 49 times / min. There are three kinds of ORS waves in V_1: (1) R_1 (1,6,11) of V_1 and R_ (1,5,9,13) of V_1 descend to rS type with a time of 0.07s, without P Wave or PR was significantly less than 0.12s, QRS occurred after 1.30s, as atrioventricular extravasation Bo. (2) R_ (3, 5, 8, 10, 12) of V_1 and R_ (3, 7, 11) of V_1 are still rS, but the amplitude of S wave is obviously smaller than the former, Time 0.07s, both before P wave, PR greater than 0.12s, sinus rhythm. (3) R_ (2, 4, 7, 9, 13) of V_1 uplink and R_ (2,4,6,8,10,12) downlink of V_1 are also rS
