[Comparison between clinical and electrophysiological data before and after definitive pacemaker implantation for the sick sinus syndrome]. / Confronto tra dati clinici ed elettrofisiologici prima e dopo impianto di PM definitivo per sindrome del seno malato.

Personal observations of 22 patients with permanent inhibited ventricular PM for SSS during the period July 1976-February 1979 and re-examined with electrophysiological study after a follow-up made for an average period 25,5 months (14 to 49 months), after PM inhibition from the outside are presented. Patients were divided into 2 groups (group 1 with bradycardia and group 2 with brady-tachy arrhythmia). In spite of relative exiguity and uniformity of this casuistry, the conclusion is drawn that CSNRT and atropine test were more significant than SACT, in particular in forms with less pathological electrophysiological parameters.

[Myocardial infarct in the aged subject. Its prognostic significance]. / L'infarto miocardico dell'anziano. Suo significato prognostico.

After our study on 72 patients over 70 years, admitted to a coronary care unit since january 1975 to december 1977 and compared with a control group of 119 patients under 70 years, we found that the hospital mortality rate was of 32% for the geriatric subjects and of 9,3% for the control group. Women over 70 years had a higher mortality: 14 (over 72) to 3 (over 119). The AMI was the more diffused, with a death percent rate higher (40%) than infarctions elsewhere localized. Between death causes, cardiogenic shock often occurred in AMI (69,5%). From a follow-up carried out in january 1978 it resulted that 57% of the 49 geriatric dismissed patients 28 survived and 15 (30,5%) died.
