Abstract：Inherited arrhythmia(IA) is a general term for a class of inherited diseases characterized by the onset of various arrhythmias, mainly including inherited ion channelopathy and inherited structural heart disease. Its risk of sudden death is high. At present, genetic testing for IA has relatively high false positive rate, or could only indicate “mutations with unclear significance”. Early identification and diagnosis of IA, and appropriate intervention are extremely important to improve prognosis. By body surface ECG examinations, we can directly observe the changes of electrical activities in the heart of IA patients, and identify special ECG manifestation patterns, so as to provide clues for its early diagnosis. Combined with domestic and foreign literatures published in recent years, this paper systematically summarizes the body surface ECG characteristics of inherited ion channelopathies such as Brugada syndrome, long QT syndrome and short QT syndrome, as well as the body surface ECG features of inherited structural heart diseases including arrhythmogenic right ventricular cardiomyopathy, hypertrophic cardiomyopathy, dilated cardiomyopathy and cardiac amyloidosis. It aims to provide references for early diagnosis of IA.
