Abstract :
We studied dialysis-associated arrhythmia in 48 uraemic patients 35 years on chronic haemodialysis (HD) ( 3 months). Holter findings showed only minor arrhythmia; atrial in 42% of patients and ventricular in 38%. ST-segment depression 1 mm was observed in 58% of patients; 80% had arrhythmia, and 36% experienced anginal pain. HD caused a significant increase in QTc, QTdc and Ca^2+ level, while K+level was signi ficantly decreased. Patients who experienced arrhythmia during HDhad higher left ventricular mass and left ventricular mass index, lower post-dialysis K+level, higher QTcand QTdc both before and after HD. They were more frequently hypertensive. ST-segment depressionwas significantly related to ventricular arrhythmia.
