  2. Diving reflex - Wikipedia

    en.wikipedia.org/wiki/Diving_reflex

    Diving reflex in a human baby. The diving reflex, also known as the diving response and mammalian diving reflex, is a set of physiological responses to immersion that overrides the basic homeostatic reflexes, and is found in all air-breathing vertebrates studied to date.

  3. Cold shock response - Wikipedia

    en.wikipedia.org/wiki/Cold_shock_response

    The diving reflex is more pronounced in aquatic mammals and is thought to have originated as a way to conserve oxygen and enhance the ability to stay underwater for longer periods. Key components of the diving reflex include: Bradycardia: The heart rate decreases significantly when the face is exposed to cold water. This helps to conserve ...

    This reflex involves apnea (loss of drive to breathe), slowed heart rate (reflex bradycardia), and reduced blood circulation to the extremities such as fingers and toes (peripheral vasoconstriction). [1] During the diving reflex, the infant's heart rate decreases by an average of 20%. [1]

    The reason: the "diving reflex," in which the body slows its heart rate and metabolism in order to conserve oxygen and energy when submerged in cold water. The pulse rate in an untrained diver ...

    Cushing reflex - triad of hypertension, bradycardia, and irregular breathing in response to elevated ICP. Diving reflex; Enterogastric reflex; Galant reflex — a primitive reflex in infants up to four months of age, a rotation of the upper body towards one or other side of the back when that side is stroked. Glabellar reflex; Golgi tendon reflex

    en.wikipedia.org/wiki/Human_physiology_of...

    The diving reflex is triggered specifically by chilling the face and breath-hold. [ 6 ] [ 19 ] The most noticeable effects are on the cardiovascular system, which displays peripheral vasoconstriction, slowed pulse rate, redirection of blood to the vital organs to conserve oxygen, release of red blood cells stored in the spleen , and, in humans ...

    Bradycardia. A slower-than-normal heartbeat. Atrial fibrillation (A-fib). An irregular and often very fast heart rate. Premature ventricular contraction (PVC). When the bottom chambers of your ...

  9. Bradycardia - Wikipedia

    en.wikipedia.org/wiki/Bradycardia

    Bradycardia, also called bradyarrhythmia, is a resting heart rate under 60 beats per minute (BPM). [1] While bradycardia can result from various pathologic processes, it is commonly a physiologic response to cardiovascular conditioning or due to asymptomatic type 1 atrioventricular block .
