Heart rate turbulence and time-domain heart rate variability analysis.

	Deceased (n = 11)	Alive Controls (n = 11)	p-Value
Number of PVCs (median, IQR)	17 [13–19]	14 [11–19]	n/a
TO (%) (median, IQR)	−0.27 [−0.54–0.34]	−1.64 [−1.99–−1.01]	0.021
TS (ms/RRI)	2.17 [0.80–3.08]	6.29 [4.20–8.02]	0.006
SDNN (ms)	14.73 ± 6.97	30.55 ± 11.15	<0.001

PVC: premature ventricular complex, TO: turbulence onset; TS: turbulence slope, IQR: interquartile range; SDNN standard deviation of NN intervals.
