Signal-averaged Electrocardiogram Shows a Heart Rate Dependent Diurnal Variation in Healthy Subjects

Signal-averaged Electrocardiogram Shows a Heart Rate Dependent Diurnal Variation in Healthy Subjects

It has not been determined if signal-averaged electrocardiograms (SAECGs) have a diurnal variation. We recorded 3-channel 24-hour ECGs in 30 healthy volunteers and calculated the following parameters for the first 500sec of every hour over the 24-hour period: the mean heart rate, the filtered QRS du...

Zusammenfassung:It has not been determined if signal-averaged electrocardiograms (SAECGs) have a diurnal variation. We recorded 3-channel 24-hour ECGs in 30 healthy volunteers and calculated the following parameters for the first 500sec of every hour over the 24-hour period: the mean heart rate, the filtered QRS duration (f-QRS), the root-mean-square voltage of the signals in the last 40msec of the QRS (RMS40), and the duration of low-amplitude signals (
