Internal Jugular/Subclavian Venous Access In Electrophysiology Study And Ablation

Multiple venous accesses are required for catheter placement during electrophysiology study and ablation. Internal jugular/subclavian venous access, though restricted nowadays, can be important in difficult situations

Ablation Techniques for Mahaim Fiber Tachycardia

Mahaim fiber exhibits atrio-ventricular node like properties and generally is localized at the lateral aspect of the tricuspid annulus. Of the varying methods for localization, ablation at the site of Mahaim potential is the most accepted and successful method. Radiofrequency ablation of Mahaim fiber has high success rates

Local Anaesthesia Suppressing Idiopathic Ventricular Tachycardia - A Cause of Non-inducible Arrhythmia During Electrophysiology Study

AbstractA 13year old boy having idiopathic ventricular tachycardia had non-inducible tachycardia twice on electrophysiology (EP) study due to suppression of arrhythmia by local anaesthetic agent, lignocaine. This case report demonstrates a cause of non-inducibility or arrhythmia during EP study and effect of lignocaine in suppression of idiopathic ventricular tachycardia

Mahaim Fiber Accelerated Automaticity and Clues to a Mahaim Fiber Being Morphologically an Ectopic or a Split AV Node

Mahaim Fiber tachycardia characteristically causes a wide QRS tachycardia with left bundle branch morphology and left axis deviation, especially in young patients, having no structural heart disease. Mahaim fiber automaticity further cements the proposition of Mahaim fiber, due to its Atrioventricular (AV) node like property, being called as an ectopic AV node

Letter by Bohora Regarding Article, "Brugada-type Electrocardiographic Pattern Induced by Electrocution"

In response to the case report of Brugada-type Electrocardiographic Pattern Induced by Electrocution by R Rangaraj et al (1), the electrocardiogram shows J point along with ST elevations in all the leads except lead III and ST depression in lead aVR. The ST segment is concave upwards in all leads along with an upright T wave except in lead V1. The characteristics features of the electrocardiogram have been classically described in pericarditis (with the exception of lead V1), which the authors should have considered as a differential diagnosis. Acute pericarditis due to electrocution also has not been described in literature prior. Hence electrocution leading to myo-pericarditis would have been a better way to probably describe the new entity
