OBJECTIVES Workers who carry out modified work during sick leave due to musculoskeletal complaints seem to return to full-capacity work earlier than colleagues not given modified work. This study evaluates whether modified work during sick leave also influences the recurrence of a new episode of sick leave. METHODS Questionnaires on physical and psychosocial workload, musculoskeletal complain...

Sinoatrial conduction is commonly assessed from features of the initial cycle after a single atrial extrastimulus or eight beats atrial pacing. In contrast, sinus node automaticity is assessed by the duration of the first interval after prolonged atrial pacing. The return cycle and initial sequences after these different methods were compared in 10 subjects with normal sinus node function and 3...

A technique for long-term atrial pacing is described. It uses the system whereby power from an external pulse-generator (including battery) is transferred through the intact skin by inductive-coupling. Once installed, there is no requirement for further surgery to effect battery changes, and the patient can control his heart rate over a wide range to suit his needs. It is suggested that pacing ...

AIM Many studies suggest that patients who receive a physiological pacemaker have a reduced incidence of atrial fibrillation compared to patients receiving a ventricular pacemaker. METHODS In order to evaluate the impact of different pacing modalities on the incidence of atrial fibrillation, we prospectively analysed 210 patients. Patients with previous episodes of atrial fibrillation were ex...

A transvenous electrode catheter technique was used for direct recording of bipolar sinus node electrograms during postpacing atrial pauses. Multiple repetitive local sinus node electrograms during atrial quiescence validate sinus node electrograms. Such atrial pauses with sinus node electrograms are due to sinoatrial block; atrial pauses without sinus node electrograms are due to overdrive sup...
