P Wave Duration/P Wave Voltage Ratio Plays a Promising Role in the Prediction of Atrial Fibrillation: A New Player in the Game

Table 4

24-hour Holter findings.

	New-onset atrial fibrillation (n = 150)	Nonatrial fibrillation (n = 490)	value
No. of PACs per hour	3.1 (2.3–3.8)	2.8 (2.1–3.6)	0.032
No. of PVCs per hour	1.4 (0.8–4.2)	1.2 (0.6–4.2)	0.070
Mean heart rate (BPM)	71.0 ± 7.4	71.1 ± 7.9	0.999
Maximal heart rate (BPM)	137.1 ± 9.6	136.3 ± 9.7	0.509
Minimal heart rate (BPM)	46.2 ± 5.7	45.9 ± 5.2	0.879

Data are presented as median (interquartile range) or mean ± SD. BPM: beats per minute; PAC: premature atrial contraction; PVC: premature ventricular contraction.
