BACKGROUND We have developed a noninvasive isochrone activation imaging (AI) system with 3-dimensional (3D) speckle tracking echocardiography (STE), which allows visualization of the wavefront image of mechanical propagation of the accessory pathway (ACP) in Wolff-Parkinson-White syndrome. METHODS AND RESULTS Patients with manifest Wolff-Parkinson-White syndrome were imaged in 3D-STE AI mode,...

The exceptional form of pregnancy specific idiopathic congestive heart failure is known as peripartum cardiomyopathy. Its onset highly observed during the last month pregnancies. Objective: To evaluate cardiac outcomes in subsequent pregnancies patients having history Methods: It a retrospective cohort study conducted at Gynae unit Timergara Teaching hospital Dir Lower KPK for duration one year...

Cardiac rhabdomyomas are benign cardiac tumours and are often associated with tuberous sclerosis. They are often asymptomatic with spontaneus regresion but can cause heart failure, arrhythmias, and obstruction. There have also been a few isolated reports of Wolff-Parkinson-White syndrome occurring in association with tuberous sclerosis and the great majority has been detected in patients with c...

Wolff-Parkinson-White Syndrome (WPW) is a term referring to Louis Wolff who published an article in 1930 that describes 11 patients suffering from episodes of tachycardia with characteristic ECG findings (ECG pattern shows bundle branch block and shortened P-R interval). In 1943, anatomical accessory pathway of conducting tissue has been described that bypasses the atrioventricular (AV) conduct...

We examined the electrophysiologic effects of verapamil in eight patients with the Wolff-Parkinson-White syndrome. Verapamil shortened the antegrade effective refractory period of the accessory pathway in three patients and abbreviated the shortest cycle length with 1:1 conduction over the accessory pathway in two patients. More significantly, verapamil decreased the shortest RR interval betwee...

Orthodromic tachycardia is the most common arrhythmia in patients with Wolff-Parkinson-White syndrome. It is often initiated during incremental ventricular pacing that requires the onset of retrograde block along the normal pathway (that is, atrioventricular [AV] node-His-Purkinje system) with concomitant retrograde atrial activation by way of the accessory pathway. However, the site of retrogr...
