[Clinical analysis of cardiac arrhythmias in patients with chronic renal failure treated conservatively. II. Evaluation of the relationship between cardiac arrhythmias and some echocardiographic indices--preliminary investigations].
Cardiac arrhythmias detected during 24-hr electrocardiographic Holter monitoring were correlated with some echocardiographic indices in 20 patients chronic renal failure (c.r.f.) on conservative treatment (10 women and 10 men, aged 43.6 +/- 9.8 years). Comparative groups consisted of 10 patients with chronic primary glomerulonephritis without arterial hypertension and renal failure (2 women and 8 men, aged 34.2 +/- 10.5 years), and 10 patients with primary arterial hypertension without clinical symptoms of renal disease (1 woman and 9 men, aged 36.6 +/- 9.5 years). In c.r.f. patients echocardiographic investigations disclosed that the left atrial diastolic dimension was within a normal range. The right ventricular diastolic dimension (RVDD) was, left ventricular systolic (LVDS) and diastolic (LVDD) dimensions and left ventricular end-diastolic volume (LVEDV) were slightly increased. The left ventricular ejection fraction (EF) was significantly lowered. In c.r.f. patients the left ventricular mass (LVM) was increased to approximately 300 g. In c.r.f. patients a significant positive correlation was found between number of ventricular extrasystoles registered within 24 hrs and RVDD. The investigation disclosed that: 1) in c.r.f. patients with arterial hypertension showed ultrasonographic signs of hypertrophic-dilated cardiomyopathy with impaired left ventricular ejection fraction; 2) in c.r.f. patients incidence and nature of cardiac arrhythmias were independent of LVM, LVDD and LVDS; 3) numbers of ventricular extrasystoles registered within 24 hrs can increase with the increase in RVDD and the decrease in EF.
