[Ambulatory treatment of paroxysmal supraventricular arrhythmias with verapamil (isoptin)].

Twenty patients, seven of them with paroxysmal supraventricular tachycardia; 8 with paroxysmal auricular flutter; 3 with paroxysmal auricular fibrillation and 2 with paroxysmal atrial tachycardia, with stage II of A-V block, were treated intravenously with isoptin, with an average dose of 0.1 mg/kg body mass. Ten, out of them, restored their sinus rhythm, 7 considerably slowed down the heart rate and 3 failed to respond.

[Our results with the secondary prevention of myocardial infarct].

The communication summed up the results from the two prospective follow-up care-prophylactic studies on patients with a past history of acute myocardial infarction (AMI). The first study covers all patients, with a past history of AMI and discharged in 1963, 1964, 1966 and 1967, a total of 378, with a follow-up period from 6 to 11 years. The direct task of the follow up was the prevention of a repeated infarction.

[Work capacity and motor activity of patients with a history of myocardial infarct].

A total of 241 patients with a past history of AMI were followed up with a view to the restoration of their capacity for work and its dependence on their motor activity. All deceased, 6 months after the acute infarction, were also included in the group. Work was resumed by 43,7 per cent from the whole group.

[Survival of patients who have had a myocardial infarct as a function of various risk factors].

Survival was studied among 250 patients with a past history of acute myocardial infarction (AMI), followed up for 5 years. A total survival of 55,6 per cent was established. The factors affecting the survival are: age, arterial hypertension, diabetes mellitus, sex, rhythm and conduction disorders, restricted physical activity, decompensation signs after AMI, increased measurements of the heart, repeated infarction as well as the presence of anginose complaints postinfarction period.
