The exercise test in 30 patients with hypertrophic (HCM) and 29 patients with dilatative cardiomoyopathy (DCM) showed a positive test with significant ST depression in half of each group. In 12 out of 30 patients with HCM and 7 out of 29 patients with DCM, exercise testing caused angina. Rhythm disturbances surprisingly did not occur in HCM but where unexpectedly frequent in DCM: in 4 cases exercise testing provoked frequent supraventricular premature beats, in 3 patients paroxysmal atrial fibrillation, and in 11 patients ventricular ectopic beats (Lown class II-IVb). Nine patients exhibited an exacerbation by at least one Lown class as compared with the electrocardiogram at rest. In patients with atypical angina pectoris and a pathological exercise test the possibility of cardiomyopathy - apart from coronary artery disease - should be increasingly considered. With provocation of arrhythmias the possibility of DCM should especially be borne in mind.

Two successful pregnancies in a patient with single ventricle and transposition of the great arteries.

A 29-year-old female with transposition of the great arteries, single ventricle, a small open ductus arteriosus and a mild aortic incompetence experienced two successful pregnancies without major complications. The benign course of pregnancy is attributed to the relatively low pulmonary vascular resistance and to the fact that the patient has not yet developed an Eisenmenger syndrome.

[The diagnosis of the sinus node syndrome].

The "specific" investigations for sinus node syndrome (SNS) in 22 patients are analyzed. SNS was defined as sinusbradycardia below 40/min and sinus-standstill over 2 sec. Atropin (1 mg i.v.), exercise test and carotid pressure were of little help in establishing the diagnosis, while Holter monitoring and sinus-node recovery time were significantly abnormal in all patients investigated.
