Electrocardiograms of 37 consecutive patients with minimal preexcitation (i.e., PR >120 ms, QRS <120 ms) were compared before and after ablation with electrocardiograms of 37 age-matched patients with atrioventricular nodal reentrant tachycardia. The presence of a septal Q wave could be used to exclude minimal preexcitation with a high degree of reliability in both patients and controls before and after radiofrequency ablation.
将37例最小预激（即PR>120 ms，QRS<120 ms）的连续患者的心电图在消融前后与37例年龄匹配的房室结折返性心动过速患者的心电图进行比较。在射频消融前后，间隔Q波的存在可用于高度可靠地排除患者和对照中的最小预激。
