不同部位陈旧性心肌梗死伴碎裂Q RS波与室性心律失常的关系
Relationship between different parts of old myocardial infarction complicating fQRS and types of ventricular arrhythmias
摘要
Abstract
Objective By analyzing the incidence of ventricular arrhythmias in patients with old myocardial infarction (OMI )in different parts complicating fragmented QRS complex (fQRS ),to explore the relationship between parts of infarction in OMI patients and arrhythmias.Methods One hundred and forty-seven OMI patients with fQRS and ventricular arrhythmia were divided into anteri-or infarction group(group A),inferior infarction group(group B)and lateral wall infarction group (group C)by ECG and colored Doppler characteristics.All of the enrolled cases underwent 24-hour Holter inspections and their results about ventricular arrhythmias were separately made comparative analysis.Results Comparing between group A and group B,the differences of incidences of non-sustained ventricular tachycardia and PVCs Lown grade 3 to 5 were statistically significant (P<0.05).Comparing between group A and group C,the incidence of total number of PVCs<720/24 h was statistically significantly different(P<0.05 ).There was no statistically significant difference between group B and group C.Conclusion Among the OMI patients complicated by fQRS and ventricular arrhythmias,the usual type of ventricular arrhythmia differs with the parts of infarction,which increases the diagnostic sensitivity of fQRS for OMI further so as to make early in-tervention and reduce the incidence of sudden cardiac death.关键词
