Abstract Objective To analyze and discuss the characteristics and meaning of premature ventricular beats of more than 10 000 times with dynamic changes of 12 lead electrocardiograms.Methods Give a retrospective analysis of the general distribution of 94 cases of patients with premature ventricular beats of more than 10 000 times，who were Classify by different conditions. Results Among 94 cases of patients with premature ventricular beats of more than 10 000 times, ① classify by pathogeny：27 cases with coronary disease, 17 cases with arrhythmia cordis, 15 cases with dilated cardiomyopathy, 11 cases with hypertensive heart disease, 8 cases with pulmonary heart disease, 5 cases with diabetes, 3 cases with chest dejected and palpitate to be checked further, 2 cases with myocardial infarction, 2 cases with myocarditis, 2 cases with angina pectoris, one case with cerebral infarction and one case with cholelithiasis. ② Classify by Lown classification: 31 cases of level Ⅱ, 21 cases of level Ⅲ, 15 cases of level ⅣA, 26 cases of level ⅣB, and one case of levelⅤ. ③ Classify by time of the occurrence of premature ventricular beats: 32 cases mostly strike in the daytime; 34 cases mostly strike at night, and 28 cases strike by day and night. ④ Classify by the frequency of premature ventricular beats(times/day): 4 cases with 40 000-50 000 times /day，9 cases with 30 000-40 000 times/day，20 cases with 20 000-30 000 times/day，and 61 cases with 10 000-20 000 times/day. Conclusion To successfully detect premature ventricular beats over 10 000 times with 12 lead dynamic electrocardiograms, first we should dig out the cause of premature ventricular beats and then combine comprehensive clinical experience, so that we can make correct evaluation and prognostic evaluation of premature ventricular beats.
