BACKGROUND: The long-term efficacy of atrial fibrillation (AF) detection and R-wave synchronization are critical safety requirements for the development of an implantable atrial defibrillator (IAD)...
Comparison of class I and class III action in atrial fibrillation (1993)
Antiarrhythmic agents with class I action have been available for decades, and those with class III mode of action for mon than 10 years. However, no randomized, controlled, direct comparison between...

Repeated signal-averaged surface electrocardiograms were recorded with a mean interval of 32·5 months (range 14 to 55 months) in 12 patients with the syndrome of arrhythmogenic right ventricular...
BLOMSTRÖM-LUNDQVIST, C., HIRSCH, I., OLSSON, S. B., EDVARDSSON, N.
Temporal signal averaging of the surface QRS (VI + V3 + V5) was performed in 16 patients with arrhythmogenic right ventricular dysplasia and in 16 normal subjects. The differences between...
Clinical value of plasma concentrations of antiarrhythmic drugs (1987)
The clinical use of plasma concentrations of antiarrhythmic agents suffers from important limitations. Any factor changing the protein binding capacity affects the free, clinically active, fraction...

A young women had been on antiarrhythmic treatment with sotalol 80–160 mg daily for three years because of ventricular tachycardia. After a quarrel she ingested an overdose ofsotalol, estimated to...
EDVARDSSON, N., HIRSCH, I., OLSSON, S. B.
The acute electrophysiologic effects of clinical doses of procainamide, lidocaine, metoprolol, digoxin and atropine upon the conduction of ventricular premature beats, were studied in 48 healthy...
Induction of Delayed Repolarization During Chronic Beta-Receptor Blockade (1985)
The development of delayed ventricular repolarization was studied in eight patients with clinical indication for chronic beta blockade. Their mean age was 74 years (range 69–81 years) and they all...

Eleven patients with bifascicular block complicating anteroseptal acute myocardial infarction were studied to determine the effect of prophylactic permanent pacing; eight of them also had transient...
Effects of acute and chronic beta-receptor blockade on ventricular repolarisation in man.
The right ventricular repolarisation phase was studied electrophysiologically after an injection of 15 mg metoprolol in 16 healthy volunteers. Eight of them were restudied after chronic treatment...
