摘要
目的观察患者死亡前心电图变化,探讨缺血性J波作为心源性猝死预测因子的可行性,为降低心源性猝死的发生率提供理论依据。方法随机抽取我院2011年5月至2015年5月收治的发生心源性猝死的患者30例,心源性非猝死患者30例,对其死亡前的同步12导联心电图缺血性J波进行测量并统计分析。结果在流行病学上,两组患者的性别、年龄、疾病类型比较,差异均无统计学意义(P>0.05)。发生心源性猝死患者中心电图出现缺血性J波的比例为96.7%,发生心源性非猝死患者中心电图出现缺血性J波比例为26.7%,心源性猝死患者死前心电图出现缺血性J波的发生率明显高于心源性非猝死患者(P<0.05)。结论心电图中缺血性J波可作为发生心源性猝死的一个高危预警指示,以提高对心源性猝死的防范。
Objective To observe the ECG changes of patients before death, explore the feasi- bility 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 non-SCD 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 an- alyzed. 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.
