Impairment in Preattentive Processing among Patients with Hypertension Revealed by Visual Mismatch Negativity

Table 4

The vMMN amplitudes elicited by duration deviant in patients with hypertension and normal controls.

Amplitude; (μV)	Hypertensive patients	Normal; controls	𝑃 value
TP7	1.5 (0.7)	−1.0 (0.7)	0.02
TP8	0.9 (0.6)	−0.7 (0.6)	0.07
A1	1.2 (0.7)	−0.9 (0.7)	0.04
A2	1.1 (0.6)	−1.3 (0.6)	0.004
O1	0.6 (0.6)	−1.3 (0.6)	0.03
OZ	0.5 (0.5)	−1.2 (0.5)	0.04
O2	0.2 (0.6)	−1.1 (0.6)	0.15
Total	0.9 (0.5)	−1.1 (0.5)	0.02

P value is for test of difference between hypertensive patients and normal controls.
