Causes and Classification of 95 Cases of "Diagnostic Ventricular Premature Beat"

CHEN Han-hua, LIU Dan, HE Xiao-chun, et al. Houjie People's Hospital of Dongguan City, Guangdong Province, 523945  
Objective: To explore the mechanism and clinical significance by all kinds of "diagnostic ventricular premature beat" namely ventricular premature beat(PVC) with Q wave. Methods: 95 cases were chose from synchronous 12-lead electrocardiogram and 12-lead dynamic electrocardiogram recording during daily-work, and they were divided into three groups, analysis it's origin?mechanism and cause of disease. Results: PVCS with Q wave originated from left ventricular in 68 patients (72%), and originated from right ventricular in 27 patients (28%). The ECG change of this PVCS with Q wave has no correlation apparent to the myocardial infarction (4/95), even to the organic heart diseases (8/95). Conclusion: It isn't very value that using ventricular premature beat with Q wave to diagnostic myocardial infarction, it must be combined to clinical closely when we diagnose myocardial infarction using ventricular premature with arched ST segment elevation.
