Overview

The most common and important ECG findings associated with systemic lupus erythematosus (SLE) include sinus tachycardia, ST segment changes, and ventricular conduction disturbances. Other ECG findings are related to late complications of SLE and may range based on the complication.

Electrocardiogram

The most common and important ECG findings associated with systemic lupus erythematosus (SLE) include sinus tachycardia, ST segment changes, and ventricular conduction disturbances. SLE can affect cardiopulmonary system in different ways including pulmonary emboli development, Libman sacks endocarditis, and conduction problems.[1][2][3][4][5][6][7][8]

Important ECG findings in SLE patients based on cardiac complication:
