[Severe persistent sub-shift of the ST segment following cardioversion in ventricular tachycardia].

The authors report a case of severe ST elevation after defibrillation which persisted for 6 days, suggesting acute myocardial infarction. The possible mechanisms of ST elevation after cardioversion and the unusually long duration of the ECG changes in this case are reviewed. The protective role of verapamil against myocardial damage is discussed.

[Outcome of myocardial infarctions complicated by heart conduction disorders in the acute phase].

Of 945 patients hospitalised for myocardial infarction between January 1st 1972 and December 31st 1975, 40 with anterior myocardial infarction (Group I-A) and 53 with posterior myocardial infarction (Group II-A) were complicated by atrioventricular and/or intraventricular arrhythmias. The average follow up period is now of 48 months (range 24 to 78 months). Their outcome was compared to two control groups of 50 anterior myocardial infarctions (Group I-B) and 50 posterior myocardial infarctions (Group II-B) uncomplicated by arrhythmias in the acute phase.

[Unstable angina with threatening coronary lesions turned down for surgery. Outcome and prognostic factors].

The aim of this study based on a series of 200 patients, was to define the outcome and the prognostic factors of patients presenting with unstable angina, according to Bertolazi's criteria [3] and at least one stenosis greater than 80% on a proximal segment of a main coronary trunc, and to determine which factors should eventually be taken into consideration in the discussion of surgical indications. 70 out of 200 patients (35%) were turned down for direct revascularisation surgery because of an ejection fraction less than 0,35 and/or a poor arterial run off. Coronary arteriography showed 30% patients with a menacing stenosis (greater than 80%) on all three vessels, 36% on two vessels and 22% on a single vessel.

[Continuous ambulatory electrocardiographic recordings using the Holter system in the late phase of hospitalization for recent myocardial infarct. Value and limitations studied in a series of 100 patients].

Repeated continuous ambulatory electrocardiography by Holter monitoring was performed after early mobilisation post-myocardial infarction in 100 patients, without ventricular extrasystoles on classical ECG. Frequent ventricular arrhythmias were recorded in 58 p. 100 cases, unrelated to the localisation of the infarct.
