[Ventricular arrhythmia in patients with chronic renal failure treated with hemodialysis].
From the group of 66 patients (pts) treated with in-hospital haemodialysis (HD), 30 pts were selected for 48 hrs monitoring of heart rhythm to register arrhythmias using Holter method. Cardiovascular complications were observed in 24 pts (80%) of the studied group; ischemic heart disease in 10 pts (33%), chronic cardiac failure in 8 pts (27%), left ventricular hypertrophy in 16 pts (53%) and hypertension in 24 pts. During 48 hrs of heart rhythm monitoring ventricular heart arrhythmias (VHA) were registered in 23 pts. 8 pts of this group had more then 100 additional ventricular beats for 24 hrs. VHA were registered before HD in 14 pts, during HD in 15 pts and after in 15 pts. The frequency of VHA pt/one hour of monitoring increased during and immediately after HD. There were no statistically significant differences between 23 pts with VHA and 7 pts without VHA with respect to the following parameters measured before HD: blood pressure, urea, calcium, kalium and magnesium blood concentrations. We found statistically significant difference between both groups of pts for creatinine values (p < 0.02); respectively 899.7 mmol/l SD 152 mmol/l versus 767 mmol/l SD 95.3 mmol/l and for interdialytic body weight increase (p < 0.012); respectively 2.65 kg SD 0.8 kg versus 2.04 kg SD 0.46 kg. Our initial results indicate that VHA appears in the majority of hemodialysed pts and that HD intensifies arrhythmogenic influence of irreversible renal failure on heart. It is also possible that non-adequate HD might be responsible for induction of ventricular heart arrhythmias during and after dialysis.
