Automated blood pressure recording: the phenomenon of blood pressure elevations during speech

The recent development of automatic non-invasive blood pressure devices has allowed the rapid and repeated assessment of both the blood pressure and pulse rate in the clinical setting. The development of this technology has allowed us to observe a striking relationship between human communication and blood pressure. Talking produces rapid increases in their systolic, diastolic and mean arterial pressures as well as pulse rate in both normotensive and hypertensive subjects. This phenomenon has been obscured by the conventional assessment techniques of blood pressure measurement. Ignoring the pattern of verbal communication during the assessment of blood pressure can result in marked differences in recorded blood pressure and its interpretation.
