The morphology of the atrioventricular (A-V) conduction system was studied by serial histologic section in two cases of tricuspid atresia type IB (without transposition of the great arteries, with ...

Few specific supraventricular rhythm disturbances other than sinus tachycardia were documented in both experimental and observational studies (most commonly nonsustained SVT, atrial fibrillation ...

Furthermore, of nine cases of nontraumatic cocaine-related death in which 12-lead ECGs had been performed, four displayed sinus tachycardia and one had atrial flutter with rapid ventricular response.

Of 8 prespecified predictors, age, MWT, left atrial diameter, left ventricular outflow tract gradient, family history of SCD, nonsustained ventricular tachycardia, and unexplained syncope were ...
