Apex beat. The apex beat (lat. ictus cordis ), also called the apical impulse, [1] is the pulse felt at the point of maximum impulse ( PMI ), which is the point on the precordium farthest outwards (laterally) and downwards (inferiorly) from the sternum at which the cardiac impulse can be felt. The cardiac impulse is the vibration resulting from ...
Overview. Your pulse is the vibration of blood as your heart pumps it through your arteries. You can feel your pulse by placing your fingers over a large artery that lies close to your skin. The ...
All-or-none law. In physiology, the all-or-none law (sometimes the all-or-none principle or all-or-nothing law) is the principle that if a single nerve fibre is stimulated, it will always give a maximal response and produce an electrical impulse of a single amplitude. If the intensity or duration of the stimulus is increased, the height of the ...
evaluation of the cardiovascular system. The cardiovascular examination is a portion of the physical examination that involves evaluation of the cardiovascular system. The exact contents of the examination will vary depending on the presenting complaint but a complete examination will involve the heart ( cardiac examination ), lungs ( pulmonary ...
Therapy is a central treatment for ICDs and impulse control associated with other underlying conditions. Examples may include: group therapy for adults. play therapy for children. individual ...
In signal processing and telecommunication, pulse duration is the interval between the time, during the first transition, that the amplitude of the pulse reaches a specified fraction (level) of its final amplitude, and the time the pulse amplitude drops, on the last transition, to the same level. The interval between the 50% points of the final ...
The aorta is the major artery that distributes oxygenated blood throughout your body. Damage to your aorta, often due to high blood pressure or fatty deposits, can cause wide pulse pressure ...
In neuroscience, threshold potentials are necessary to regulate and propagate signaling in both the central nervous system (CNS) and the peripheral nervous system (PNS). Most often, the threshold potential is a membrane potential value between –50 and –55 mV, [1] but can vary based upon several factors. A neuron 's resting membrane ...
