Abstract

Forty-two patients with hypertensive heart disease but without coronary macroangiopathy were examined for ventricular arrhythmias by means of 24-h, long-term electrocardiograms (ECG). They were divided into two groups according to specific criteria. Group 1 was composed of 30 patients with left ventricular hypertrophy but normal ventricular volumes, as determined by ventriculography. Group 2 comprised 12 patients with left ventricular hypertrophy and dilated left ventricles. By means of two 24-h, long-term ECGs, the mean absolute number of ventricular extrasystoles was ascertained and severity was determined according to the classification of Ryan et al. On average, patients in group 2 showed 7.830 +/- 6.579 extrasystoles, a significantly higher (p less than 0.001) number than in patients in group 1 who had 1.132 +/- 2.639 extrasystoles/24 h. Moreover, 67% of patients in group 2 had Ryan's class 4a ventricular arrhythmias (couplets) or 4b disorders (ventricular tachycardia). However, corresponding rhythm disorders could be found in only 7% of the patients in group 1. A comparison of hemodynamic parameters and ventricular arrhythmias showed that a decreasing left ventricular ejection fraction (EF, expressed in %), a decreasing m...Continue Reading

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
