The advent of transseptal puncture has enabled the study of atrial fibrillation mechanisms, while epicardial access has enabled exploration of the epicardium in ventricular arrhythmias (ventricular tachycardia/ventricular fibrillation [VF]).1,2

Paco Dardon (@PacoDardon), and it’s a privilege to present it as a formal review due to the many pathophysiological, and electrophysiological, phenomenon at play. McLaren : ACLS attempts to simplify this process, suggesting cardioversion for unstable tachycardias, and anti-arrhythmics for stable wide complex tachycardias.

Chagas disease (ChD) was associated with increased rates of ventricular tachycardia and ventricular fibrillation in ICD patients only in the initial two periods, but there was no statistical difference in the last period. Progressive decline across periods in mortality rates among patients with implantable cardioverter-defibrillator (ICD).

Fragmented QRS is a marker of myocardial scar and consequent arrhythmias in ischemic and nonischemic cardiomyopathy. Ebstein’s anomaly may be associated with right sided accessory pathway in ventricular pre-excitation, that is WPW syndrome, with or without atrioventricular re-entrant tachycardia.

Here was his ED ECG: There is sinus tachycardia (rate about 114) with nonspecific ST-T abnormalities. The absence of any wall motion abnormality makes ischemic cardiomyopathy very unlikely. An ECG was recorded: This shows a regular narrow complex tachycardia at a rate of about 160. BP:143/99, Pulse 109, Temp 37.2 °C

ABSTRACT Introduction Radiofrequency ablation is a cornerstone therapy for patients with ischemic cardiomyopathy (ICM) presenting with ventricular tachycardia (VT). In this context, ablation is typically performed endocardially as a first-line approach.
