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.
Pulsus alternans is diagnosed by first palpating the radial or femoral arteries, feeling for a regular rhythm but alternating strong and weak pulses. Next, a blood pressure cuff is used to confirm the finding: the cuff is elevated past systolic pressure and then slowly lowered cuff towards the systolic level.
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 ...
Symptoms include deep and fast respiration, weak and slow pulse, and respiratory pauses that may last for 60 seconds. Subclavian steal syndrome arises from retrograde (reversed) flow of blood in the vertebral artery or the internal thoracic artery, due to a proximal stenosis (narrowing) and/or occlusion of the subclavian artery.

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 ...
Here’s what heat stroke symptoms look like, according to the NWS: Throbbing headache. Confusion. Fainting. Nausea and dizziness. Rapid and strong pulse. If someone is experiencing these symptoms ...
Examples include a higher risk of blood clotting within the heart and a higher risk of insufficient blood being transported to the heart because of a weak heartbeat. Other increased risks are of embolization and stroke, heart failure, and sudden cardiac death.
Vasodilatory shock, vasogenic shock, or vasoplegic shock is a medical emergency belonging to shock along with cardiogenic shock, septic shock, allergen-induced shock and hypovolemic shock.
