患者男性,31岁,心慌、乏力2月余,体检未发现异常。图A、B为同次心电图非同步记录,图示:基本心律为窦性,可见频发的室性早搏,联律间期不固定,变动在0.55～0.86s之间,多成串发生(E_(1～6)、E_(9～14))。E_9、E_(15)形态略异于其他室性搏动,其前有相关P波,属室性融合波。最短的异搏周期(E_(7～8)为0.44s,如以此做为室性节律的基础周期,可测算出长异搏周期E_(6～7)、E_(14～15)以及成串出现的E_(1～6)、E_(9～14)恰能被之整除,变异系数仅为4.4％,说明此例为一例典型的室性并行搏动(VPSR)。仔细测量发现VPSR中的E_(1～6)异搏周期由0.52s递增至0.90s,E_(9～11)由0.80s至0.95s,E_(11～14)呈不
Male patient, 31 years old, palpitation, fatigue more than 2 months, physical examination found no abnormalities. Figure A, B for the same time asynchronously recorded ECG, the icon shows: the basic rhythm of sinus, frequent premature ventricular contractions can be seen, the joint law is not fixed between 0.55 ~ 0.86s, between a series of occurrences ( E_ (1 ~ 6), E_ (9 ~ 14)). E_9, E_ (15) morphology is slightly different from other ventricular beats, before the relevant P wave, is a ventricular fusion wave. The shortest circulation period (E_ (7 ~ 8) is 0.44s). If we use this as the basic period of ventricular rhythm, we can calculate the long-term period E_ (6 ~ 7), E_ (14 ~ 15) The E_ (1 ~ 6) and E_ (9 ~ 14) of the string just happened to be divisible by them, the coefficient of variation was only 4.4%, indicating that this case is a typical ventricular parallel beat (VPSR) E_ (1 ~ 6) esophageal cycle increased from 0.52s to 0.90s, E_ (9 ~ 11) from 0.80s to 0.95s, E_ (11 ~ 14)
