mean aortic pressure
21Afterload — In cardiac physiology, afterload is used to mean the tension produced by a chamber of the heart in order to contract. If the chamber is not mentioned, it is usually assumed to be the left ventricle. However, the strict definition of the term… …
22Pathophysiology of hypertension — A diagram explaining factors affecting arterial pressure The pathophysiology of hypertension is an area of active research, attempting to explain causes of hypertension, which is a chronic disease characterized by elevation of blood pressure.… …
23Pulse — For other uses, see Pulse (disambiguation). Pulse evaluation at the radial artery. In medicine, one s pulse represents the tactile arterial palpation of the heartbeat by trained fingertips. The pulse may be palpated in any place that allows an… …
24Multifunction cardiogram — Multifunction CardioGramTM (MCGTM) is an FDA and AMA approved diagnostic tool used to diagnose myocardial ischemia due to Coronary Artery Disease (CAD). MCG records resting ECG data between the Myocardium and intra cardiac blood flow to… …
25Vasoconstriction — is the narrowing of the blood vessels resulting from contraction of the muscular wall of the vessels, particularly the large arteries, small arterioles and veins. The process is the opposite of vasodilation, the widening of blood vessels. The… …
26Complications of hypertension — Main complications of persistent high blood pressure Complications of hypertension are clinical outcomes that result from persistent elevation of blood pressure.[1] Hypertension is a risk factor for all …
27Heart rate — is the number of heartbeats per unit of time, typically expressed as beats per minute (bpm). Heart rate can vary as the body s need to absorb oxygen and excrete carbon dioxide changes, such as during exercise or sleep. The measurement of heart… …
28Chronotropic — effects (from chrono , meaning time, and tropos, a turn ) are those that change the heart rate. Chronotropic drugs may change the heart rate by affecting the nerves controlling the heart, or by changing the rhythm produced by the sinoatrial node …
29Baroreflex — In cardiovascular physiology, the baroreflex or baroreceptor reflex is one of the body s homeostatic mechanisms for maintaining blood pressure. It provides a negative feedback loop in which an elevated blood pressure reflexively causes blood… …
30Diastole — Heart during ventricular diastole. Diastole (  /d …
