【Abstract】 Objective To summarize the clinical and electrocardiographic features of heart tumor with ventricular tachycardia as the first clinical presentation. Methods The clinical and electrocardiographic features of ventricular tachycardia which was the first manifestation of ventricular intramural tumor were analyzed in 5 cases admitted from Dec.1992 to July.1999.The diagnosis was initially made by cardiac imaging,and finally was confirmed by surgery and pathology with the ventricular intramural tumor.Results All the 5 patients had paroxysmal ventricular tachycardia with a rate from 160 to 200 beats per minute.There was dizziness in three cases and near syncopy in two patients.However,they all had no history of apparent heart disease.The sites of origin of the ventricular tachycardia as predicted from the standard electrocardiography (ECG) were in agreement with the true location of the intracardial tumor,and confirmed by intracardiac electrophysiologic study in one patient. Conclusions For the patients with ventricular tachycardia as first clinical manifestation with no history of heart disease,ventricular intramural tumor may be a possible etiology.Cardiac imaging studies are needed.The origin of the ventricular tachycardia as predicted on standard ECG often coincides with the location of the ventricular intramural tumor.更多还原
