Most of the patients in this study with spinal muscular atrophy were found to have tremors of the isoelectric line in the electrocardiogram (ECG) tracings. There were a total of 47 cases of SMA (mean age 40.8 months). All three types of SMA had a similar incidence (about 80%) of tremors in the tracings (p = 0.885). In 7 cases the ECG tremors had an intermittent pattern. ECG tremors were commonly found in the majority of SMA patients and this finding, though non-specific, may suggest a possible SMA diagnosis.
本研究中大多数脊髓性肌萎缩症患者在心电图（ECG）描记图中被发现等电位线有震颤。共有47例脊髓性肌萎缩症患者（平均年龄40.8个月）。所有三种类型的脊髓性肌萎缩症在描记图中震颤的发生率相似（约80%）（p = 0.885）。7例患者的心电图震颤呈间歇性模式。心电图震颤在大多数脊髓性肌萎缩症患者中普遍存在，这一发现虽然不具有特异性，但可能提示脊髓性肌萎缩症的诊断。
