Transient and rapid QRS widening associated with J - wave pattern predicts impending ventricular fibrillation in experimental myocardial infarction
Background: Certain types of the early repolarization (ER) phenomenon, previously considered to be benign, have been reported to be associated with ventricular fibrillation (VF), both in population-based studies and in the myocardial infarction (MI) settings. Objective: Our aim was to analyse whether QRS widening and appearance of Jwave-pattern in experimental MI settings is predictive of VF. M...

متن کاملEarly repolarization is an independent predictor of occurrences of ventricular fibrillation in the very early phase of acute myocardial infarction.
BACKGROUND Recent evidence has linked early repolarization (ER) to idiopathic ventricular fibrillation (VF) in patients without structural heart disease. However, no studies have clarified whether or not there is an association between ER and the VF occurrences after the onset of an acute myocardial infarction (AMI). METHODS AND RESULTS This study retrospectively included 220 consecutive pati...
متن کاملEarly repolarization pattern and its day-to-day dynamic change as markers for ventricular fibrillation in patients with vasospastic angina.
AIMS An early repolarization (ER) pattern is a risk factor for ventricular fibrillation (VF) in certain diseases. However, it is unclear whether this association holds for patients with vasospastic angina (VSA). Moreover, the reported long-term follow-up of implantable cardioverter defibrillator (ICD) therapy for VSA patients is limited to 3 years. This study aimed to clarify the relation betwe...
متن کاملImpending Myocardial Infarction
IT HAS LONG BEEN known that attacks of myocardial infaretion are frequently preceded by premonitory pain. The reported incidence of such warning symptoms usually varies from 30 to 50 per cent and the fatality rate in these series has ranged from 15 to 43 per cent. Soon after introduction of anticoagulants in the treatment of acute myocardial infaretion, several authors1-3 conjectured that this ...
