Nedo Nadi (9 June 1894 – 29 January 1940) was one of the best Italian fencers of all time. He is the only fencer to win a gold medal in each of the three weapons at a single Olympic Games and won the most fencing gold medals ever at a single Games—five. Nadi won six Olympic gold medals in total. [1]
Pulsus alternans is a physical finding with arterial pulse waveform showing alternating strong and weak beats. [1] It is almost always indicative of left ventricular systolic impairment, and carries a poor prognosis.
The normal range has since been revised in textbooks to 50–90 bpm for a human at total rest. Setting a lower threshold for bradycardia prevents misclassification of fit individuals as having a pathologic heart rate. The normal heart rate number can vary as children and adolescents tend to have faster heart rates than average adults.
The nadi system is mentioned in the Chandogya Upanishad (8~6 cc. BCE), verse 8.6.6. [7] and in verses 3.6–3.7 of the Prasna Upanishad (second half of the 1 millennium BCE). As stated in the last, 3.6 "In the heart verily is Jivātma. Here a hundred and one nāḍis arise. For each of these nāḍis there are one hundred nāḍikās. For each ...
Major factors influencing cardiac output – heart rate and stroke volume, both of which are variable. [1]In cardiac physiology, cardiac output (CO), also known as heart output and often denoted by the symbols , ˙, or ˙, [2] is the volumetric flow rate of the heart's pumping output: that is, the volume of blood being pumped by a single ventricle of the heart, per unit time (usually measured ...
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 nadir of American race relations was the period in African-American history and the history of the United States from the end of Reconstruction in 1877 through the early 20th century, when racism in the country, and particularly anti-black racism, was more open and pronounced than it had ever been during any other period in the nation's history.
ISO 80000-3:2019 defines a physical quantity called rotation (or number of revolutions), dimensionless, whose instantaneous rate of change is called rotational frequency (or rate of rotation), with units of reciprocal seconds (s −1).
