A rapid, weak, thready pulse due to decreased circulation combined with tachycardia [duplication?]. Cool, clammy, and mottled skin (cutis marmorata) due to vasoconstriction and subsequent hypoperfusion of the skin. Distended jugular veins due to increased jugular venous pressure.
A rapid, weak, thready pulse due to decreased blood flow combined with tachycardia; Cool skin due to vasoconstriction and stimulation of vasoconstriction; Rapid and shallow breathing due to sympathetic nervous system stimulation and acidosis; Hypothermia due to decreased perfusion and evaporation of sweat; Thirst and dry mouth, due to fluid ...
Watson's water hammer pulse, also known as Corrigan's pulse or collapsing pulse, is the medical sign (seen in aortic regurgitation) which describes a pulse that is bounding and forceful, [1] rapidly increasing and subsequently collapsing, [2] as if it were the sound of a water hammer that was causing the pulse.
However, pulse pressure variation as a measure of fluid responsiveness is only valid in patients without spontaneous breaths or arrhythmias. The accuracy of pulse pressure variation also can be compromised in right heart failure, decreased lung or chest wall compliance, and high respiratory rates .
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 ...
Pulsus paradoxus, also paradoxic pulse or paradoxical pulse, is an abnormally large decrease in stroke volume, systolic blood pressure (a drop more than 10 mmHg) and pulse wave amplitude during inspiration. Pulsus paradoxus is not related to pulse rate or heart rate, and it is not a paradoxical rise in systolic pressure.

The impulse then spreads through both ventricles via the bundle of His and the Purkinje fibers causing a synchronized contraction of the heart muscle and, thus, the pulse. [citation needed] In adults, the normal resting heart rate ranges from 60 to 90 beats per minute. The resting heart rate in children is much faster.
