患者男性,26岁,发作性心慌、胸闷7年余。临床诊断:心律失常原因待查。附图(见第171页)系1988年6月4日同次记录。附图A示房性早搏、室性早搏及由房早所致的短阵发作的室上速。房早的异位P’不同于心速时的P~-,也不同于窦性P波,P′-R=0.16s,P~--R及R-P~-规整,P~--R/R-P~-<1,P~--P~-规整。附图B示室一上速发作前个QRS宽人畸形,形态及偶联间期与图1室早相同,证实为室早,其前有异位房P′,P′-R=0.06s,此P′与QRS无关,形成干扰性房室分离。P′与图1心动过速发作时第1个房性P′形态相似,P′-P~-间期相等。因而,提示室上速仍由房早引起,而非室早所致。
Patient male, 26 years old, paroxysmal palpitation, chest tightness more than 7 years. Clinical diagnosis: the cause of arrhythmia to be investigated. The drawing (see page 171) is the same as recorded on June 4, 1988. Figure A shows atrial premature beats, ventricular premature beats and short shots caused by atrial septal supraventricular tachycardia. Atrial ectopic P ’is different from P ~ - at heart rate, and is different from sinus P wave. P’-R = 0.16s, P ~ -R and RP ~ RP ~ - <1, P ~ - P ~ - regularity. Figure B shows a rapid onset of the room a QRS wide human deformity, morphology and coupling interval and room early in Figure 1, confirmed as early room, before the ectopic P ’, P’-R = 0.06s, This P ’has nothing to do with QRS, forming a disturbed atrioventricular separation. P ’and Figure 1 tachycardia when the first atrial P’ morphology is similar, P’-P ~ - interval is equal. Thus, suggesting that the morning sickness is still caused by the morning room, rather than as early as caused.
