A pulse deficit between the PMI and periphery may occur in some arrhythmias, such as premature ventricular contraction or atrial fibrillation. Sustained apex beat, namely prolonged upward cardiac force during systole in a physical exam, can be seen in some chronic conditions such as hypertension and aortic stenosis, especially in elderly and ...
The pulse is the rate at which the heart beats while pumping blood through the arteries, recorded as beats per minute (bpm). [11] It may also be called "heart rate". In addition to providing the heart rate, the pulse should also be evaluated for strength and obvious rhythm abnormalities. [11] The pulse is commonly taken at the wrist (radial ...
In medicine, the pulse is the rhythmic throbbing of each artery in response to the cardiac cycle (heartbeat). [1] The pulse may be palpated in any place that allows an artery to be compressed near the surface of the body, such as at the neck (carotid artery), wrist (radial artery or ulnar artery), at the groin (femoral artery), behind the knee (popliteal artery), near the ankle joint ...

The following outline is provided as an overview of and topical guide to cardiology, the branch of medicine dealing with disorders of the human heart. [1] The field includes medical diagnosis and treatment of congenital heart defects, coronary artery disease, heart failure, valvular heart disease and electrophysiology.
This bibliography of biology is a list of notable works, organized by subdiscipline, on the subject of biology. [ 1 ] [ 2 ] Biology is a natural science concerned with the study of life and living organisms , including their structure, function, growth, origin, evolution, distribution, and taxonomy. [ 3 ]
As metabolic rate increases, the lifespan of an organism is expected to decrease as a direct result. The rate at which this occurs is not fixed and thus the -45° slope in this graph is just an example and not a constant. The rate of living theory postulates that the faster an organism's metabolism, the shorter its lifespan.
