Objective: To determine and analyze the ECG patterns of 40 patients with systemic lupus erythematosus (SLE).

Methods: Clinical data of 40 patients with SLE managed in Zhangye People’s Hospital from April 2015 to November 2016 were analyzed, but with particular attention to features of their ECGs.

Results: Twenty three cases (57.5%) of the 40 patients with SLE had clinical symptoms of heart injury. The average time the SLE patients with heart injury had been suffering from the disease before admission into the hospital was significantly (p < 0.05) longer than that of non-heart injury patients. There were 15 cases (37.5%) with abnormal ECG, 12 cases (30.0%) with ST-T change, 8 cases (20.0%) with arrhythmia, and 5 cases (12.5%) with low limb lead voltage. There were 2 cases of death out of the 40 patients, consisting of one male and one female. The cause of death in one of them was heart failure, while the other death was due to uremia with acute pulmonary edema.

Conclusion: Changes in ECG of SLE patients is common and should be an important parameter that physicians should routinely examine for SLE cases with heart injury, in order to achieve improved prognosis of the patients’= condition.
