Abstract Objective To explore the electrocardiogram（ECG） signal of non-specific intraventricular block and the correlation with disease. Methods Analysis retrospectively ECG signals of 71 pa- tients with non-specific intraventricular block at different ages， and the relationship with disease. Results Non-specific intraventricular conduction block occurred in the sex ratio of 65: 6（male to female）.Incidence at three ages was 32%，30%，38% respectively. In the group less than 40-year-old， the main population was without organic heart disease patients and health people（78%）. More than 60-year-old， the main cause was coronary heart disease（CHD） and hypertension（59%）. Non-specific intraventricular block with ST-T variation is common in patients with organic heart disease（59%）. Conclusions There was no difference of incidence at three ages， but is common in male patients.In younger patients，non-specific intraventricular block is common in patients without organic heart disease and healthy people，however， in elders，the pathogeny is mainly hypertension or CHD（coronary heart disease）. There is larger clinical significance when nonspecific intraventricular conduction block is combined with other ECG abnormalities.
