Ambulatory electrocardiography in car workers.

48-hour ambulatory electrocardiography in dynamite workers and controls.

Comparison of the prevalence of ventricular and supraventricular premature beats with 24-hour Holter electrocardiography between hypertensive and normotensive shift workers in a manufacturing company.

We conducted 24-hour Holter electrocardiography (ECG) among shift workers to assess whether there were differences in the prevalence of ventricular apd supraventricular premature beats between hypertensive (HT) and normotensive (NT) workers. Among the selected 24 male shift workers, 20 were fitted with 24-hour Holter ECG monitors. Nine workers were in the HT group and 11 the NT group. The preva...

Ambulatory surgery in Spain

In Spain, ambulatory surgery (AS) is called major ambulatory surgery to emphasise that the focus is on procedures previously or still conducted in an in-patient setting with overnight stay, and that endoscopies and minor surgical excisions are excluded (these procedures were traditionally performed as office procedures). According to the guidelines on major ambulatory surgery produced by the Sp...

The heart and tuberous sclerosis. An echocardiographic and electrocardiographic study.

Cross sectional echocardiography, 12 lead electrocardiography, and 24 hour ambulatory electrocardiography were performed in eleven patients with tuberous sclerosis. Echocardiography showed single or multiple intramyocardial masses, most commonly in the ventricular septum, suggestive of rhabdomyomata in seven of the eleven cases. One patient with a normal echocardiogram showed ventricular pre-ex...

Elevated blood pressure, decreased heart rate variability and incomplete blood pressure recovery after a 12-hour night shift work.

Shift work has been associated with increased risk of cardiovascular disease. This study was designed to determine the hemodynamic effects of 12-hour (12-h) shifts, and changes in blood pressure (BP) and heart rate variability (HRV) during 36 h rest time following 12-h shifts. Fifteen male shift workers with a mean age of 32.9 yr were recruited from a semiconductor factory. Ambulatory BP (AmBP)...
