We have read with interest the article titled 'Anatomic Twist to a Straightforward Ablation' authored by Mandeep Singh Randhawa et al [1]. A detailed report of a commendable and unique successful Atrio-Ventricular junction ablation for rapid ventricular-rate control in a patient with Atrial Fibrillation in the setting of left atrial isomerism, common atrium and an interrupted infra-hepatic Infe...

Cases in which epilepsy and atrio-ventricular (AV) block coexist are unusual. A 31-year-old man presented with syncope. Holter ECG showed the second-degree AV block and the longest cardiac pause was 6.3 seconds. Even after receiving pacemaker, he repeated consciousness cloudiness. Electroencephalogram revealed spike and waves on the left temporal region, suggesting complicated with complex part...

BACKGROUND Proper pacemaking of the heart requires a specific organization of the sinoatrial (SA) node. The SA node drives the surrounding atrium but needs to be protected from its hyperpolarizing influence, which tends to suppress pacemaker activity. It has been suggested that the hyperpolarizing atrial influence is minimal at the site of the central nodal area. METHODS AND RESULTS Atrio-sin...

The effect of atrial contraction on cardiac function is reviewed in patients with dual chamber and rate-responsive ventricular pacemakers. The question posed was is there any haemodynamic, clinical or prognostic advantage of AV synchrony in dual chamber pacemakers in comparison to rate-responsive ventricular pacemakers? Optimal AV delay in dual chamber pacing favours cardiac performance at rest...

Atrioesophageal fistula is an extremely rare but often fatal late complication of atrial fibrillation ablation procedures resulting from massive thermal injury to the esophagus and surrounding structures. Causes of death include cerebral air embolism, massive gastrointestinal bleeding, and septic shock. Because of its exceptionally low rate of occurrence, no predictors of lesion development hav...
