A diagnosis of primary cardiac tumors was achieved by two-dimensional echocardiography in 3 patients. Two of them were female neonates, born of the 29th and 40th gestational week who had shown intrauterine arrhythmias. Subsequently, we were able to diagnose tuberous sclerosis in both. The third child, a 121/2 year old boy, with already diagnosed tuberous sclerosis, presented an electrocardiographical preexcitation syndrome. Because of the multiplicity of the tumors and the association with tuberous sclerosis we presumed that the tumors were rhabdomyomas. As it is known that rhabdomyomas show no, or only a minimal postnatal growth, we decided neither to perform a heart catheterization nor to treat them surgically unless the children show hemodynamical deterioration, although the tumors were huge in both neonates. The subsequent 14 months showed a clear regression in the size of the tumors. One of the neonates was successfully treated with amiodarone because of ventricular tachycardia. The second neonate didn't require any treatment. We conclude that: Surgical management is only necessary in patients presenting with cardiac insufficiency and/or arrhythmias that are resistant to conventional medical treatment. Primary cardiac tumors should be looked for in patients presenting with arrhythmias, even when occurring already during intrauterine life. Diagnostic measures in order to diagnose tuberous sclerosis in patients with cardiac tumors are necessary and vice versa.

21 patients accusing previous syncopal attacks, without myocardial infarction, preexcitation syndrome or severe cardiac failure were submitted to a 24 hrs Holter monitoring with 10 min. of esophageal electrocardiogram. Nine patients were considered as cases of sinus bradycardia (mean HR = 49.5 +/- 4.4 b/min). Other 12 patients with normal basic sinus rhythm were admitted for ventricular premature beats (HR = 65.5 +/- 8.7 b/min.). Fourier transformation analysis (mean method, linear interpolation) was used for determination of the heart rate variability (HRV) and other two variables: variation range (VR)--(longest-shortest cycle/mean basic sinus cycle, %) and differences of sinus cycle length (DSCL = maximal difference of any two consecutive sinus cycle, ms). In all the 9 patients with low sinus rhythm and in 7 patients with normal basic sinus rhythm, at least one episode of critical bradycardia (under 45 b/m) was observed. In 3 of the 9 patients with sinus bradycardia at least two episodes of nonsustained ventricular tachycardia were observed. In all the 12 patients with ventricular premature beats, many episodes of nonsustained ventricular tachycardia were registered. In all the 21 studied patients low and very low frequency HRV was observed. The VR and DSCL presented a significant dependence on age, but this relationship was weaker than the established limits of normality. In the cases of sick sinus syndrome with sinus bradycardia and/or severe ventricular tachyarrhythmias, the noninvasive Holter analysis of HRV can determine the correct diagnosis and indications for permanent cardiac pacing and antiarrhythmic drug therapy.
