Abstract：Objective To observe the ECG changes of patients before death, explore the feasibility of ischemic J wave in predicting sudden cardiac death(SCD), and provide theory evidence of reducing the incidence of SCD. Methods Thirty SCD patients and another 30 nonSCD ones were randomly selected in our study, who were admitted in our hospital from May 2011 to May 2015. Their ischemic J waves in synchronous 12 lead ECG before death were measured and statistically analyzed. Results In epidemiology, there was no significant difference in gender, age and disease type between the two groups(P>0.05). The proportion of patients with ischemic J waves was 96.7% among SCD cases while the proportion was 26.7% among non-SCD ones. The incidence of ischemic J waves in SCD patients before death was significantly higher than that in non-SCD ones(P＜0.05). Conclusion Ischemic J waves in ECG can be regarded as a high-risk early warning predictor of SCD, which strengthens prevention measures
