[Ten year cardio-cerebro-vascular mortality and morbidity in a Southern Italy cohort: the VIP Project data].

Rationale: In Italy the mortality data were obtained almost exclusively from the data RENCAM (Name Causes of Death Register), while there are few prospective surveys. In order to assess whether there are particular epidemiological conditions in the geographical area of Mercato S. Severino, in Southern Italy, we have studied, and reassessed at ten years (1998/99 - 2008/09), a cohort of adult general population in a project of cardiovascular epidemiology and prevention.

Heart rate, PR, and QT intervals in normal children: a 24-hour Holter monitoring study.

A dynamic electrocardiographic Holter monitoring study was performed in 32 healthy children (20 males and 12 females, age range 6-11 years old), without heart disease, according to clinical and noninvasive instrumental examination. We evaluated atrioventricular conduction time (PR), heart rate (HR), and QT interval patterns defining the range of normality of these electrocardiographic parameters. The PR interval ranged from 154 +/- 10 ms (mean +/- SD) for HR less than or equal to 60 to 102 +/- 12 ms for HR greater than or equal to 120 (range 85-180).

Long-term management of exercise-induced myocardial ischemia. Diltiazem versus propranolol, a double-blind, crossover study.

The authors performed a long-term, double-blind, crossover study on the effect of two drugs (propranolol, 40 mg t.i.d.
