Abstract

In order to investigate the incidence of severe ventricular arrhythmias, the 24-h ambulatory ECG of 55 patients with aortic valve disease (NYHA classes I-IV; stenosis: n = 24; regurgitation: n = 18; mixed lesions: n = 13) without coronary heart disease were evaluated with regard to the number of premature ventricular beats and according to the Lown classification. Ventricular arrhythmias were found in 73% of all patients (Lown classes III-V: 38%; Lown classes IV-V: 20%). A significant relation between the degree of arrhythmias and the gradient or severity of regurgitation of the aortic valve could not be established. However, there was a significant linear correlation between the left ventricular ejection fraction and the degree of arrhythmias (stenosis: r = 0.60; regurgitation: r = -0.72; mixed lesions: r = 0.78; all p less than 0.005). Complex arrhythmias of Lown classes III-IV are rare (less than 10%) in patients with good left ventricular function (LVEF greater than 60%). There was a history of palpitations in 81% of patients with Lown classes III-V. According to these data, ventricular arrhythmias are present in a large number of patients with aortic valve disease. The degree of arrhythmia does not correlate to the transva...Continue Reading

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.

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.
