fQRS波预测陈旧性心肌梗死患者室性心律失常的价值
Value of fQRS in predicting ventricular arrhythmia of patients with old myocardial infarction
摘要
Abstract
Objective To investigate the predictive value of fQRS for ventricular arrhythmias occurrence in patients with old myocardial infarction (OMI). Methods Selected 235 patients with OMI for ECC examination, then divided them into pathologic Q waves group (Group A), OMI with fragmented QRS complex (fQRS) (Group B) , OMI with both pathological Q wave and fQRS (Group C), according to QRS ECG characteristics. Then all the cases were examined by dynamic ECG, and comparative analysis was made for the ventricular arrhythmias occurrence of three groups. Results Occurrence of ventricular arrhythmia in Group A, B and C was respectively 69. 1 % (47/68), 74.4% (90/121), and 71.7% (33/ 46), thus differences between three groups were not significant; occurrence of two or more ventricular arrhythmia was 20.6% (14/68), 40.5% (49/121), 43.5% (20/46), which in Group C and B were both significantly higher than that in group A (both P<0.05). The incidence of PVCs>720/ 24 h, grade 3 to 5 ventricular contraction as Lown classification in Group C and B were both significantly higher than those in Group A (P < 0.05); the incidence of polymorphic PVCs in Group A was significantly lower than that in Group B (P<0.05). Conclusions fQRS is closely related with ventricular arrhythmia occurrence ; fQRS is a predictive factor to independent cardiac events for OMI patients.关键词
