CASE REPORTS Arrival of Excitation at the Right Ventricular Apical Endocardium ill Wolff-Parkinson-White Syndrome

Arrival of excitation at the right ventricular apical endocardium in Wolff-Parkinson-White syndrome type B.

Arrival of excitation at right ventricular apical endocardium in Wolff-Parkinson-White syndrome type A, with and without right bundle-branch block.

Filtered bipolar right ventricular apical (RVA) and His bundle electrograms, using electrodes only i mm apart, were recorded in two patients with intermittent WPW type A with and without 'complete' right bundle-branch block. In beats with exclusive normal pathway conduction and 'complete' right bundle-branch block, the HV and V-RVA intervals represented His-to-left ventricular endocardial and l...

Echocardiography in Wolff-Parkinson-White Syndrome

Twenty-six patients with Wolff-Parkinson-White (WPW) syndrome were studied by echocardiography. They were classified into the following WPW types: anterior right ventricular pre-excitation (Type I) -six patients; posterior right ventricular pre-excitation (Type II) -six patients; posterior left ventricular preexcitation (Type III) fourteen patients. Twenty-three patients were in WPW at the time...

Radiofrequency catheter ablation in the treatment of Wolff-Parkinson-White syndrome

Introduction: Tachyarrhythmias in Wolf Parkinson White (WPW) syndrome, can be a life threatening factor. Antiarrhythmic drug therapy in this syndrome, has not been completely acceptable. Efficacy, safety and economy of Radio Frequency Catheter Ablation (RFCA) in western studies, has made it as the treatment of choice. In the present study, efficacy of RFCA in the ablation of accessory pathway...

Supraventricular tachycardia and atrial flutter associated with a coronary sinus diverticulum: A case report

The case of a patient with narrow QRS-complex supraventricular tachycardia and atrial flutter is described. The 12-lead surface electrocardiogram (ECG) revealed sinus rhythm with ventricular pre-excitation and negative δ waves in leads II, III and aVF, indicating Wolff-Parkinson-White syndrome with a posteroseptal accessory pathway (AP). Coronary sinus angiography revealed the presence of a div...
