为了进一步确定正常人室性早搏的发作情况、频度和特性,对101例经非侵入性和侵入性试验证实为无疾病者进行24小时动态心电图监护。其中男性51例,女性50例;平均年龄48.8±10岁(范围为16～68岁);体格检查、X 线胸片、心电图、超声心动图、极量运动试验、右心及左心导管术和冠状动脉造影均为正常。24小时动态心电图描记系用手提式 Avionics 磁带记录器,录取 V_1 及 V_5 导联。早搏指数系 RR′间期除先前正常心跳的 QT 时间;失常指数系室性早搏的 QRS 时限除以正常心跳的QRS 时限。记录每小时的最大和最小心率,每小时的总心搏,每种形态的室性早搏数,用电子计算机进
In order to further determine the onset, frequency and characteristics of normal premature ventricular contractions, 101 patients with non-disease confirmed by non-invasive and invasive tests were monitored by 24-hour Holter monitoring. Including 51 males and 50 females; mean age 48.8 ± 10 years (range 16-68 years); physical examination, X-ray, electrocardiogram, echocardiography, maximal exercise test, right heart and left heart catheterization And coronary angiography were normal. The 24-hour Holter trace uses the hand-held Avionics tape recorder to enroll the V_1 and V_5 leads. The premature beat index is the RRT interval in addition to the QT time of the previous normal heartbeat; the anomaly index is the QRS duration of premature beats divided by the QRS duration of normal beats. Record the hourly maximum and minimum heart rate, the total heart rate per hour, the number of premature ventricular contractions per pattern, using a computerized
