[The left ventricle in chronic renal failure patients. Ecocardiographic and poligraphic study before and after hemodialysis (author's transl)].

Echocardiographic and systolic time intervals changes found after hemodyalisis in 16 patients with chronic renal failure are analysed and discussed. Echocardiogram shows: significant (p less than 0.05), no change statistically significant of end-systolic diameter, fractional shortening, mean velocity of circumferential shortening (VcF), and amplitude of septal motion. Systolic time intervals show: significant reduction (p less than 0.001) of total electromechanical systole (SEM), mechanical systole (SM) and left ventricular ejection time (LVET), and increase (p less than 0.05) of pre-ejection period (PEP) and the ratio PEP/LVET (p less than 0.005). The reason of these changes is the post-dialytic fluid's loss (2140 +/- 760 g) followed by left ventricular end-diastolic diameter and volume reduction which decreases stoke volume and LVET (according to Frank-Starling's law). It has not been possible to draw concordant and definitive conclusions on the post-dialytic left ventricular function. PEP lengthening would give evident for myocardial involvement (but pre-load and after-load changes modifies it), while the other data are slightly affected (VcF, fractional shortening, and amplitude of septal motion) or improved (amplitude and peak velocity of posterior wall motion).

["T'orsade de pointe" and amiodarone (author's transl)].

A long Q-T interval syndrome is described, followed by "torsade de pointe" and by irriducible ventricular fibrillation that is ascribed to a badly conducted therapy with amiodarone, in a patient affected by mitral valve disease, microcitaemia and hemolitic intercurrent moderate jaundice.

[Serial analysis of "P-terminal force-V1" (PTF-V1) in acute myocardial infarction (author's transl)].

P-terminal force on horizontal plane (PTF-V1) has been studied following clinical and statistical criteria in 122 subjects with acute myocardial infarction (A.M.I.) and in a control comparable group. Also the other parameters of the P-wave have been analysed. PTF-V1 is a more reliable sign than the last and has shown some modifications in connection with the clinical changes in A.M.I. The more pathologic values have been found in anterior myocardial infarction and in infarction with pump failure. There has not been possible to find so strict relation between pathologic PTF-V1 and mortality.
