[An echocardiographic study of the isovolumetric relaxation period in the myocardial infarction (author's transl)].

Variations have been examined in the left ventricle's transverse dimension (TD) during the isovolumic relaxation period (IRP) in 12 healthy subjects and in 38 patients with anterior or antero-inferior infarct. Healthy subjects have shown no increase in TD during the IRP whereas this fact has been noted in 24 out of 38 (63%) patients with different distribution according to the site of the infarct (29%) for inferior infarcts and 86% for anterior or antero-inferior infarcts). These results suggest that inferior infarct compared with anterior infarct, implies a less incoordinate ventricular contraction. It is thus stressed the opportunity of echocardiography approach for the identification of the incoordinate ventricular contraction and for the determination of IRP duration which may be exposed to serious mistakes using the traditional phono-apexcardiographic method.

[Subxiophoyd echocardiography: pulmonary artery or aorta (author's transl)].

Six patients with chronic obstructive pulmonary diseases, have been examinated by subxiophoyd echocardiography associated with ultrasonic contrast of right heart. It is detected that the vessel placed behind anterior cavity is aorta. This is confirmed by study of calcific aortic stenosis too, where the calcifications allows sure localisation of the vessel. Main pulmonary artery, or its branches, is instead visible behind aorta.

[Syncope during potassium depletion (author's transl)].

The onset of serious arrhythmias during potassium depletion occurs rather frequently in female subjects who have undergone hypotensive-diuretic treatment, independently from the duration and doses of drugs. These arrhythmias which produce a cardiac arrest, can also occur in subjects not affected with heart disease. They are not necessarily preceeded by clinical prodrumus or other types of minor arrhythmias not accompanied by other important electrocardiographic or serum-logical alterations of hypokaliemia. The most commonly observed type is the "torsades de pointe", though cases of ventricular tachycardia or ventricular fibrillation are also documented. The ethiopathogenesis is discussed with regard to the alterations of the basic electrocardiogram as well as to the kind of major arrhythmia. In most cases , lidocaine has given the most satisfactory thmias, results in the treatment of these arrhythmias, probably because of the modality of the action which is substantially different from the other antiarrhythmic drugs.
