[The role of prolonged cardiac pacing in management of secondary bradyarrhythmias based on personal experiences].

Three patients with bradyarrhythmia who were admitted to the Department for urgent pacemaker implantations are presented. The careful clinical evaluation revealed that these arrhythmias were remarkably secondary to underlying diseases (e.g. severe coronary heart disease, valvular defects). Surgical treatment applied in these cases (coronary bypass grafts, valve replacement) has resulted in successful outcome. We concluded that in some patients the pacemaker implantation alone, without heart surgery, would not be beneficial enough.

Intradialytic erythrocyte volume changes.

Haemodialysis (HD) should affect the erythrocytes, which constitute more than 99% of blood cells. The aim of this study was to reinvestigate the intradialytic changes in erythrocyte water content (MCV). MCV was measured during 81 HD (47 uncomplicated, 34 with hypotension), and 16 isolated ultrafiltrations (UF) performed in stable, haemodialysed adults (12 males and 8 females). The MCV following uncomplicated HD (n = 32) did not differ from the predialysis value. Significant MCV increase accompanied the HD initiation (4.9 +/- 9.0 fl, P less than 0.001), UF (2.99 +/- 1.49 fl, P less than 0.001) and hypotension (1.8 +/- 3.1 fl, P less than 0.01). This was independent of sodium and potassium within the cells and plasma. Erythrocyte oedema occurred in situations known to accompany both bioincompatibility reactions and blood volume decrease. Intradialytic MCV increase may reflect a response to these events, possibly hormonal, and needs further investigation.
