| Description: |
Patients requiring maintenance hemodialysis (HD) show high mortality rate and sudden cardiac death. Previous studies have shown that at the end of the HD session the QT interval on standard ECG prolongs and its dispersion increases, but little is known on the long-term variation of QT interval and on its relationship with heart rate changes. The dynamic behaviour of ventricular repolarization assssed in 29 consecutive patients (age 66 ± 11; 15 females) on chronic HD from 24 hour Holter recordings. A dedicated algorithm (ELA medical) automatically measured QT and RR interval from 2880 30-sec segments. QT corrected for heart rate (QTc) and the slope of the QT/RR regression line were analysed during a 20-hour period before HD, the HD session, the hour before HD and during each HD hour. In all patients K, Mg and Ca plasma concentrations were measured before and after HD. QTc was longer during HD than before HD (447 ± 28 vs 429 ± 22 msec, p |
