Relation between repolarization and refractoriness in the human ventricle: Cycle length dependence and effect of procainamide [PDF]
The cycle length dependence of the action potential duration and the effective refractory period of the right ventricular endocardium were investigated in 24 patients undergoing electrophysiologic studies for suspected ventricular tachycardia. The action

Procainamide Versus Amiodarone for Stable Ventricular Tachycardia.
Electrical cardioversion is an effective treatment for termination of ventricular tachycardia (VT)1,2 but is typically performed with procedural sedation, and thus involves associated risk.

Systemic lupus erythematosus (SLE) induced by quinidine [PDF]
Only two definite cases of quinidine-induced systemic lupus erythematosus (SLE) are reported in the English-language literature. We have treated five patients who had an SLE-like syndrome while receiving quinidine.

Previous observations demonstrated that cimetidine decreased the clearance of procainamide (PA) and/or N-acetylprocainamide (NAPA; the primary metabolite of PA) resulting in the increased systemic exposure and the decrease of urinary excretion.

Atrial electrical remodeling (ER) after spontaneous or pacing-induced atrial fibrillation has been previously described in humans. We investigated atrial ER induced by a 5-minute period of rapid atrial pacing and the pharmacologic effects of verapamil ...

Unmasked by Fever: Diagnosing Brugada Syndrome After Ventricular Fibrillation Arrest
A 65-year-old man presented to the emergency department after he was resuscitated from cardiac arrest due to ventricular fibrillation. Coronary angiography demonstrated no evidence of coronary artery disease. Follow-up electrocardiograms (ECGs) were also
