我们分析了 11 例新记录的多形性室性心动过速患者对 Ia 型抗心律失常药物的反应,在没有使用所有抗心律失常药物的情况下进行的运动测试结果。将这些结果与 11 名年龄、性别和心脏病相匹配的对照患者的结果进行比较,以确定服用抗心律失常药物时出现心律失常恶化的患者 QT 间期对运动测试的反应是否异常。两组在休息时和运动 3 分钟时评估 QT、RR 和 QTc 间期(通过 Bazett 方法)。静息时,病例患者和对照患者的 QT 间期(410 +/- 13 与 386 +/- 11 毫秒)、RR 间期(890 +/- 56 与 781 +/- 43 毫秒)或校正 QT 间期(438 +/- 10 与 438 +/- 4 毫秒)没有显着差异。两组对运动都表现出相似的变时性反应。两组运动后的 QT 间期均缩短(p 小于 0.001),但对照组患者的缩短程度(至 310 +/- 9 毫秒)比病例患者的缩短程度(至 357 +/- 11 毫秒)更大(p = 0.06)。因此,经历 Ia 型药物促心律失常作用的患者的 QTc 间期出现了矛盾的增加,但对照患者则没有(增加到 482 +/- 8 与 431 +/- 5 毫秒;p 小于 0.001)。 11 名病例患者中有 10 名在运动后 QTc 间期延长超过 10 毫秒,但 11 名对照患者中只有 1 名(p 小于 0.001)。(摘要截断为 250 字)
We analyzed the results of exercise testing performed in the absence of all antiarrhythmic drugs in 11 case patients with newly documented polymorphic ventricular tachycardia in response to type Ia antiarrhythmic agents. These results were compared with those found in 11 control patients matched for age, sex, and heart disease to determine whether the response of the QT interval to exercise testing was abnormal in patients who developed worsening of arrhythmia while taking antiarrhythmic drugs. QT, RR, and QTc intervals (by Bazett's method) were evaluated at rest and at 3 minutes of exercise in both groups. At rest, there was no significant difference in the QT interval (410 +/- 13 vs. 386 +/- 11 msec), RR interval (890 +/- 56 vs. 781 +/- 43 msec), or corrected QT interval (438 +/- 10 vs. 438 +/- 4 msec) in the case patients and the control patients. Both groups demonstrated a similar chronotropic response to exercise. The QT interval shortened in both groups with exercise (p less than 0.001), but the degree of shortening tended to be greater in the control patients (to 310 +/- 9 msec) than in the case patients (to 357 +/- 11 msec) (p = 0.06). Thus, there was a paradoxical increase in the QTc interval in the patients who experienced a proarrhythmic effect of type Ia drugs but not in the control patients (to 482 +/- 8 vs. 431 +/- 5 msec; p less than 0.001). Ten of 11 case patients but only one of 11 control patients had an increase in QTc interval of more than 10 msec with exercise (p less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)
