Pacemaker
Heart rate
Radial pulse
Carotid pulse
Pressure exerted by the blood upon the walls of the blood vessels, especially arteries, usually measured by means of a sphygmomanometer and expressed in millimeters of mercury.

Hypertension
Hypotention
An acute episode of heart disease marked by death or damage of heart muscle due to insufficient blood supply to the heart muscle.
Carotid pulse
