Abstract:
Objective To explore causes and high risk electrocardiogram expression of cardiac syncope caused by malignant rapid ventricular arrhythmia.Methods Forty-eight patients were analysed, they had cardiac syncope once or more that after which were admitted to the hospital. Results The basic causes of cardiac syncope were individed following types in 48 patients: coronary heart disease with acute or dated myocardial infarction,dilated or hypertrophic cardiomyopathy,hypokalaemia were ordinarist inducer.Torsade de pointes(TdP) were most common type of malignant rapid ventricular arrhythmia.They had some high risk electrocardiogram expression: secondary long QT syndrome,Brugada's syndrome,idiopathic abnormal J wave,complex ventricular ectopic beats,acute myocardial infarction with ST-T electrical alternation; or extensive anterior myocardial infarction with tombstone ST segment elevation,dilated cardiomyopathy with advance QRS complex low voltage.They were different electrocardiographic and clinical characteristic. Conclusion The cardiac syncope caused by malignant rapid ventricular arrhythmia is not single and independent clinical entity, which presents different the causes and high risk electrocardiogram expression.
