Systolic blood pressure is depending on the arm position when home blood pressure is measured with a wrist or an arm validated monitor.

Objectives: To compare home blood pressure (BP) values obtained with two validated OMRON (wrist or arm) monitors used in the same individual sequentially, but with two different hand positions.

Methods: In 200 hypertensive individuals referred to hypertension specialists, a self-measurement of BP was performed sequentially with an OMRON M4-I (arm cuff, A/A, British Hypertention Society validation) and an OMRON RX-I (wrist cuff, B/B, BHS validation). Each patient recorded home BP during two periods of 4 days with three measures in the morning and three in the evening.

[Systolic blood pressures are not comparable when home blood pressure is measured with a wrist or an arm validated monitor].

Objectives: To compare home blood pressure values obtained with two validated OMRON (wrist or arm) monitors used sequentially in the same subject.

Methods: In 265 hypertensive subjects referred to hypertension specialists, a self measurement of blood pressure was performed sequentially with an OMRON M4-I (arm cuff, A/A, BHS validation) or OMRON RX-I (wrist cuff, B/B, BHS validation). Each patient recorded home blood pressure during two periods of 4 days with 3 measures in the morning and 3 in the evening.
