Wolff-Parkinson-White syndrome in Patients With MELAS.
BACKGROUND Tissues with high energy demands, such as the heart, are susceptible to the effects of mitochondrial DNA point mutations. OBJECTIVE To investigate the frequency of Wolff-Parkinson-White (WPW) syndrome among a phenotypically and genotypically homogeneous cohort of patients with MELAS (mitochondrial encephalopathy, lactic acidosis, and strokelike episodes) and the A3243G mutation mos...

Forty-nine patients with Wolff-Parkinson-White syndrome, ages 7 weeks to 51 years, were studied with isopotential body surface maps during normal sinus rhythm, atrial pacing or induced atrial fibrillation. The location of the accessory pathway was determined by multicather electrophysiologic study or surgical ablation of the accessory pathway. When fusion was minimized and ventricular activatio...

This paper reports a patient with Wolff-Parkinson-White syndrome who presented with a tachycardia showing an unusual QRS morphology closely resembling that of a ventricular tachycardia. On reversal to a normal rhythm the electrocardiogram showed changes of a type A preexcitation, with subsequent conversion to a type B pattern. This phenomenon was observed on two separate occasions. Such convers...

متن کامل[Wolff-Parkinson-White Syndrome].
Wolff-Parkinson-White (WPW) syndrome is a cardiac conduction disorder that presents with potentially life-threatening consequences. Wolff-Parkinson-White syndrome-induced dysrhythmias account for 20% of all supraventricular tachycardias that occur in the general population. Clinical presentations range from no symptoms to a sudden cardiac arrest. The risk of sudden death is always present with ...
