Cardiac abnormalities are frequently associated with myotonic dystrophy (MD), and electrocardiographic (ECG) changes are not rare in these patients. The most common ECG abnormalities are PQ or QT interval prolongation, low P wave amplitude, ST elevation or depression, negative T waves, conduction and rhythm abnormalities. We analysed ECG changes in 42 patients with MD. ECG abnormalities were obvious in 24 (57%) patients. The most prevalent ECG changes were sinus bradycardia and low P wave amplitude, occurring in 23 (55%) patients. Nineteen (45%) patients had QTc prolongation. PQ prolongation occurred in 16 (38%) patients, abnormal Q waves in 9 (21%), intraventricular conduction defects in 7 (16%) and QRS prolongation or T wave changes in 4 (9%) patients. We found no ST alterations. ECG changes were more frequent in patients with severe disease, but it was not statistically significant. There was no correlation between age and ECG abnormalities in our patients.
心脏异常常与强直性肌营养不良（MD）相关，这些患者出现心电图（ECG）改变并不罕见。最常见的心电图异常是PQ或QT间期延长、P波振幅降低、ST段抬高或压低、T波倒置、传导和节律异常。我们分析了42例MD患者的心电图变化。24例（57%）患者心电图异常明显。最常见的心电图变化是窦性心动过缓和P波振幅降低，23例（55%）患者出现此情况。19例（45%）患者QTc延长。16例（38%）患者PQ延长，9例（21%）患者出现异常Q波，7例（16%）患者有室内传导阻滞，4例（9%）患者有QRS增宽或T波改变。我们未发现ST段改变。病情严重的患者心电图变化更频繁，但无统计学意义。我们的患者年龄与心电图异常之间无相关性。
