The ST length and T wave were investigated electrocardiographically and clinically in 200 patients with a short PQ interval in the electrocardiogram, independent of the length and shape of the QRS complex. In group A (Lown-Ganong-Syndrome LGL), we often found a narrow, pointed, positive P wave and a narrow QRS complex in the electrocardiogram in addition to the short PQ interval, and also a tendency to respiratory arrhythmia. Clinically this was frequently a matter of young women with a tendency to paroxysmal tachycardia and autonomic dystonia. A James bundle or even a short AV conduction pathway with a small heart might be considered as the origin of this LGL syndrome. A particular classification of patients with short PQ intervals and S-T deformation (Group B) in organic heart disease has not yet been described in the literature to our knowledge. The results of our investigations in group C (WPW syndrome) correspond in the main to those given in the literature.

The object of the present investigation was the discovery of the arrhythmias in the patients with prolapse of the mitral valve (PMV), the types of arrhythmias, the factors favouring them, the therapy used. In a group of 126 patients suffering from PMV, 25 had mitral insufficiency, and 48% of the cases had arrhythmias too. The ventricular arrhythmias existed in 18 patients, in the most of them as ventricular extrasystoles. Only in 2 cases, ventricular paroxysmal tachycardia was noticed, and only one case of ventricular fibrillation was recorded. The following conclusions were drawn from the study: the increase of arrhythmias is low, their appearance is correlated with mitral insufficiency, ventricular arrhythmias are predominant, the majority are benign, they are more frequent than in the patients with neurovegetative dystonia (if considering the prolapse associated with systolic murmur), necessity of periodic control for discovering the cases with high risk of ventricular arrhythmias with malignant potential.
