[Sudden cardiac death in the case of an apparently healthy heart]

After a brief survey the authors present two of their observations on sudden death with obviously intact heart. The first observation was on a male, aged 43, with three incidents of sudden death, successfully reanimated. Between the paroxysms, frequent ventricular extrasystoles, type "early" were recorded, falling upon T-wave. After the anti-arrhythmic treatment the ventricular extrasystoles disappeared and no new incidents occurred. Three years later the patient was capable of working, without complaints. The second case concerns a female, aged 32, pregnant 7--8 month, hospitalized with light manifestations of late toxicosis and auricle extrasystoles, type parasystoles some of them recorded upon T-wave. The patient suddendly died in obviously excellent health. Ventricular fibrillation was recorded on ECG, not overcome very likely, because of the delayed reanimation. At necropsy, a heart with normal dimensions was found with scanty small cicatrices in the myocardium, probably resulting of past myocarditis.
