| During the primary percutaneous coronary intervention, the patients with st-segement elevation acute myocardial infarction may emerge reperfusion arrhythmia (STEAMI).Investigating the clinical character and significance of reperfusion arrhythmia.Asscessing the risk of the patients, in order to improve the success rate of operation.MethodsAnalysising of the Clinical datas from April 2006 to December 2008 in the Cardiology Department of Chinese medical university hospital, those Clinical datas must be from STEAMI patients with the time of continuous chest pain not more than 12 hours, and then going on emergency percutaneous coronary intervention (PCI). Total 110 cases. Observing the relationship between reperfusion arrhythmia(RA) and Criminals vessels, the relationship between reperfusion arrhythmia and the time of incidence to coronary artery recanalization, the relationship between reperfusion arrhythmia and infarct size.Reasult56 cases of the 110 cases occurred reperfusion arrhythmia. (accounting for 50.90%); RCA lesion group the incidence of RA is higher than LAD lesions (P<0.01), and mostly slow arrhythmia, a variety of arrhythmia and malignant ventricular arrhythmia is also higher than the incidence of LAD lesions; The reperfusion arrhythmia incidence of the patients with STEAMI operated PCI within 6h is significantly higher than the patients with STEAMI operated PCI between 6h and 12h(p<0.05); The incidence of reperfusion arrhythmias is no significant difference between the patients with limited myocardial infarction and the patients with extensive anterior wall myocardial infarction (p>0.05)Conclusion1.Reperfusion arrhythmia and the sites of Criminals Vascular, the time of incidence to coronary artery recanalization have certain relationship. RA and Infarct size have not relationship.2.RCA lesions more susceptible to RA, which the more common slow arrhythmia, the incidence of malignant arrhythmia is also higher.3. RA general short-term prognosis is favorable. |
