A clinical analysis of 46 cases with arrhythmogenic right ventricular cardiomyopathy
2008
Objective:To retrospectively analyze the clinical features of patients with arrythmogenic right ventricular cardiomyopathy(ARVC).Method:The clinical features,diagnosis and treatment were analyzed in 46 patients(35 males) with ARVC according to the criteria established by European Society of Cardiology.Result:The averaged age was(42.4±19.5) years old(0.25~75).Palpitation was presented in 30 patients(65.2%),heart failure in 21 patients(45.7%),syncope in 16 patients(34.8%) and a family history of sudden death in 3 patients(6.5%).ECG changes included:the average QRS duration ≥110 ms(60.9%);epsilon(e) wave(47.8%);T wave inversion in precordial leads(78.3%);reduced extremity amplitude(43.5%);arrhythmia in various types(23 patients including 3 types and more).Dilated cardiomyopathy was diagnosed in 10 patients,unclassified cardiomyopathy in one,Ebstein's anomaly in one and 26.1% of patients were indefinited at the first visit.Conclusion:Complex clinical manifestations were showed in the patients with ARVC,with higher misdiagnosis rates.ARVC would be learned again to raise the correctness of final diagnosis.
