Comparison of ST segment changes on standard and Holter electrocardiogram during exercise testing.

In order to compare the ST segment changes recorded simultaneously on Holter (Del Mar Avionics 445B recorder and DCG VII Scanner) and standard electrocardiogram, 22 patients with chest discomfort and normal resting ECG were evaluated during exercise testing. The conventional ECG was recorded using chest lead V5 and a modified lead II. The Holter recording was done using the bipolar chest lead CM5 and the same modified lead II.

[Familial hypertrophic myocardiopathy: complex ventricular arrhythmias in healthy family members].

The aim of the present study was to evaluate the electrocardiographic changes among the members of a family affected by hypertrophic cardiomyopathy. Seventeen unaffected members and 8 affected members were studied by 24-hour Holter monitoring. Twenty-five normal controls were also studied by 24-hour Holter monitoring.

[Stroke: Holter monitoring in 15 hypertensive patients].

The objective of the study is to evaluate the prevalence of ventricular arrhythmias during acute stroke in hypertensive patients: 15 hypertensive patients (9 males and 6 females; mean age 56 +/- 5) without clinical and electrocardiographic evidence of organic heart disease underwent 24 hour Holter monitoring during acute stroke. Another group of 15 uncomplicated hypertensive patients (14 males and 1 female, mean age 49 +/- 5) without clinical and electrocardiographic evidence of organic heart disease underwent 24 hours Holter monitoring as controls. The Holter monitoring was repeated in 8 patients who survived during follow-up, after a mean period of 15 months: 13/15 (86%) patients with acute stroke had ventricular arrhythmias against the 7/15 (47%) in the control group.

[Distributions, mean values and correlations of various coronary risk factors in a population of Veneto].

During the National Research Council (CNR) program called Atherosclerosis-Risk Factors 2 (ATS-RF2) a random sample of 1903 subjects (50.1% male) aged 20-59 years was examined in the general population of Mirano-Venice. Mean values of serum total cholesterol and triglycerides, body mass index, as well as systolic and diastolic blood pressure were assessed.

[Prevalence, characteristics and clinical correlates of left ventricular hypertrophy in stable hypertension. Echocardiographic study].

251 in stable hypertensives were studied with M-Mode and two-dimensional echocardiography, in order to evaluate the prevalence of left ventricular hypertrophy (LVH), its patterns and clinical correlates. 54 subjects (21%) had been treated previously with antihypertensive drugs while the remaining 197 (79%) had not. A normal left ventricle was found in 69 subjects (27.
