Delta wave and QRS complex polarities have been extensively studied in preexcitation syndromes. However, only limited data exist about ventricular depolarization and repolarization in the setting of maximal preexcitation in relation to the site of insertion of the accessory pathway. Therefore this study was designed to systematically analyze cardiac depolarization and repolarization in patients with maximal preexcitation. We analyzed the polarity of the QRS complex and T wave on the frontal plane on the conventional 12-lead electrocardiogram in 118 patients with maximal preexcitation. Fast atrial pacing was used to provoke maximal ventricular preexcitation. The 32 patients with a left lateral accessory pathway showed right-axis deviation of the QRS complex (110 +/- 20 degrees) with a left-axis deviation of the T-wave axis (-40 +/- 25 degrees). The 54 patients with a posteroseptal accessory pathway had a left axis of the QRS complex (-50 +/- 20 degrees) with a right-axis deviation of the T-wave axis (95 +/- 15 degrees). The 11 patients with a right lateral accessory pathway had a left axis of the QRS complex (-40 +/- 20 degrees) and a right axis of the T wave (110 +/- 10 degrees). In 7 patients with a left anterolateral accessory pathway and 14 patients with a right anteroseptal accessory pathway, the axis of the QRS complex was 50 +/- 25 degrees and 45 +/- 20 degrees, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)
在预激综合征中，δ波和QRS波群的极性已得到广泛研究。然而，关于最大预激情况下心室去极化和复极化与旁路插入部位的关系，仅有有限的数据。因此，本研究旨在系统分析最大预激患者的心脏去极化和复极化情况。我们分析了118例最大预激患者常规12导联心电图额面上QRS波群和T波的极性。采用快速心房起搏诱发最大心室预激。32例左侧旁路患者的QRS波群呈电轴右偏（110±20度），T波电轴左偏（-40±25度）。54例后间隔旁路患者的QRS波群电轴左偏（-50±20度），T波电轴右偏（95±15度）。11例右侧旁路患者的QRS波群电轴左偏（-40±20度），T波电轴右偏（110±10度）。7例左前外侧旁路患者和14例右前间隔旁路患者的QRS波群电轴分别为50±25度和45±20度。（摘要截短至250字）
