	Linear	Parabolic
N = 50
n	127	128
α (n.u.)	0.17	0.36
STDα (n.u.)	0.014	0.029
Max. Err. (ms)	13.4	43.6
N = 300

The Maximum Variation in milliseconds the model can generate (Max. Err.) for both linear and parabolic models in lead Z. These values are reported for a number of measurements (N) equal to 50 and 300. Values are based on the overall 24‐hour Holter recordings. n.u.: no unit.
