常规动态心电图监测采用改良的V_1和V_5导联。初步研究表明,与这2对导联相比的另7对双极导联之中,垂直胸骨导联(负极置于胸骨上切迹的下方,正极置于剑突之前方)记录的P波最大。 58±23岁(1个月～88岁)的 46(男 20、女26)例患者拟诊心律失常而作24小时动态心电图监测,同时记录垂直胸骨导联和改良的 V_1导联。垂直胸骨导联同改良的 V_1导联相比:P波的面积和正向高度较大(2
Conventional Holter monitoring uses modified V_1 and V_5 leads. Preliminary studies have shown that among the other seven pairs of bipolar leads compared to the two pairs of leads, the P wave recorded by the vertical sternum leads (the anterior pole is placed below the suprasternal notch and the anterior pole is placed in front of the xiphoid process) maximum. A total of 46 (20 males and 26 females) patients aged 58 ± 23 years (1 month to 88 years) were enrolled in a 24-hour ambulatory electrocardiographic monitoring of arrhythmia while recording vertical sternal leads and modified V 1 leads. Vertical sternum lead compared with the improved V_1 lead: P wave area and positive height is greater (2
