    Abstract:
    UNLABELLED: The accuracy of the Holter System ICR 6201-G3 was investigated by evaluation of 32 Holter recordings taken randomly from the hospital's ECG laboratory. All events were classified into true positive, false positive and false negative diagnoses. Sensitivity (S) and predictive accuracy (PA) were calculated. RESULTS: QRS complexes: S 99.9%, PA 99.9%; supraventricular premature beats: S 98.3%, PA 81.1%; single ventricular premature beats: S 96.8%, PA 97.4%; ventricular couplets: S 96.4%, PA 95.6%; ventricular salvos: S 98.6%, PA 90.8%; pauses: S 100%, PA 91.7%. It is concluded that despite a relatively good overall accuracy of automatic arrhythmia detection, on account of the lower accuracy in the evaluation of all clinically important arrhythmias and of the markedly worse accuracy in some instances, a fully automatic use of the system cannot be recommended. Repetitive ventricular arrhythmias and asystolies must be controlled by hand.
