[Sick sinus syndrome in childhood. A case report (author's transl)].

The case of an eight-year old child suffering from sick sinus syndrome (SSS) is reported. The patient showed S-A conduction disturbances (Mobitz 1 sinoatrial exit block) as noted in two sequential 24-hour recording periods, and a pathologic response to atropine test. An involvement of the A-V node was also present, made clear by a first and a second degree Mobitz 1 block. The clinical, laboratory and noninvasive data excluded an organic cardiopathy. Idiopathic SSS was, therefore, diagnosed. The rare occurrence of this syndrome in the childhood, and the usefulness of Holter monitoring in its detection is emphasized.

Ambulatory monitoring in normal children.

An Ambulatory ECG monitoring (AM) was carried out over a 24 hr. period on 90 healthy children divided into 3 age groups (lst week of life, 1 year of age and 5 years of age). There was a high number (about 50%) of unusable registrations because of detached electrodes, broken leads, and artifacts. The AM on children is characterised by: a) high values of the maximum frequencies (mean maximum absolute frequency 178 at birth, 164 at one year, 154 at 5 years); b) a great difference between the maximums and minimums; c) hourly variations related, above all, to feedings in the new-born babies and of a circadian type in the 5 years old children; d) almost constant marked sinus arrhythmias (80%); extremely rare extrasystolia (7.5 atrial, 2.5 ventricular) and always isolated; e) presence of upward (27%) and downward deflection (10%) of the J point sometimes accompanied by modifications of the T wave (22%).

Dynamic electrocardiogram in normal subjects during sexual activity.

An Holter ECG has been recorded for 24 h in 10 couples that had during such time a normal sexual contact. The age varied from 20 to 37 years for women, and 25 to 49 years for men. The average of maximum, medium and minimum rate was major in women than in men. During the initial phase of sexual activity an increase of about 30 beats per minute is verified up to an average rate of 104 b.p.m. without any differences between the two sexes. During realization phase the rate increased ulteriorly. This kind of increase is major and more prolonged in women (137 X 2.8 min.) with respect to men (126 X 2.1 min). The maximum rate observed during sexual contact wasn't superior to the maximum rate observed during the day. We conclude that a normal sexual activity doesn't represent a very pronounced strain, provoking a tachycardia equal to 60-70% of maximum rate of patient and for a short period of time. This should be kept in mind when judging on sexual activity of cardiac patients.

[Effectiveness of two Ca-antagonistic drugs on angina pectoris: nifedipine and verapamil versus nitroderivative and beta-blocking drugs (author's transl)].

The Authors, using cycle ergometer tests, assess the effectiveness of two Ca-antagonistic drugs, nifedipine and verapamil, administered full strength to patients suffering from typical angina from effort. The true effectiveness of these drugs was tested by comparing the results with those obtained with placebo, isosorbide dinitrate and propranolol. The effect of nifedipine proved statistically significant (p less than 0.01) with respect to the parameters: double product, time of insurgence of angor and time of appearance of electrocardiographic anomalies. Verapamil proved slightly significant (p less than 0.05) only with regard to time of appearance of electrocardiographic anomalies. There follows a brief discussion of the differences between these results. Isosorbide dinitrate and propranolol increase tolerance to effort with respect to placebo treatment. These results are statistically significant on all parameters used.

[Analysis of the Luciani-Wenckebach phenomenon in the A-V node. II. Relationship between conduction and recovery times].

We have studied 20 cases Wenckebach A-V block by atrial pacing. The relationships between conduction time and recovery time of N. AV Wenckebach point, basal A-H time and A-H time of first cycle beat were analysed. No correlation was found between W point, basal A-H and A-H of the first beat by analysing the A-H = f (H-A) we found different curves which occur when the first A-H is longer or shorter than 110. These data were discussed on the basis of modern hypotheses of electrophysiological mechanism of Wenckebach periodism.
