Abstract:
Assessment of heart rate variability from 24-h recordings requires a high-quality Holter, expensive equipment and multistage processing of recordings. We compared a new personal computer-based digital QRS detector system with a Holter recorder, and found the two methods to be equally accurate in time and frequency domain measures of heart rate variability.
