Post-cardiac arrest syndrome. Post-cardiac arrest syndrome (PCAS) is an inflammatory state of pathophysiology that can occur after a patient is resuscitated from a cardiac arrest. [ 1 ] While in a state of cardiac arrest, the body experiences a unique state of global ischemia. This ischemia results in the accumulation of metabolic waste which ...
Cardiac arrest, also known as sudden cardiac arrest, is when the heart suddenly and unexpectedly stops beating. [11][1] As a result, blood cannot properly circulate around the body and there is diminished blood flow to the brain and other organs. When the brain does not receive enough blood, this can cause a person to lose consciousness.
Postural orthostatic tachycardia syndrome (POTS) is a condition characterized by an abnormally large increase in heart rate upon sitting up or standing. [1] POTS is a disorder of the autonomic nervous system that can lead to a variety of symptoms, [10] including lightheadedness, brain fog, blurred vision, weakness, fatigue, headaches, heart palpitations, exercise intolerance, nausea ...
Respiratory arrest is a serious medical condition caused by apnea or respiratory dysfunction severe enough that it will not sustain the body (such as agonal breathing). Prolonged apnea refers to a patient who has stopped breathing for a long period of time. If the heart muscle contraction is intact, the condition is known as respiratory arrest.
Post-concussion syndrome(PCS), also known as persisting symptoms after concussion, is a set of symptomsthat may continue for weeks, months, or years after a concussion. PCS is medically classified as a mild traumatic brain injury(TBI). [1][2][3][4][5]About 35% of people with concussion experience persistent or prolonged symptoms 3 to 6 months ...
The person may be nauseated, pale, and sweaty for several minutes or hours. Causes. [edit] Reflex syncope occurs in response to a trigger due to dysfunction of the heart rate and blood pressure regulating mechanism. When heart rate slows or blood pressure drops, the resulting lack of blood to the brain causes fainting. [12] Vasovagal.
Post-polio syndrome (PPS, poliomyelitis sequelae) is a group of latent symptoms of poliomyelitis (polio), occurring at about a 25–40% rate (latest data greater than 80%). They are caused by the damaging effects of the viral infection on the nervous system and typically occur 15 to 30 years after an initial acute paralytic attack.
Symptoms include weakness, confusion, decreased breathing rate, and decreased reflexes. Hypermagnesemia can greatly increase the chances of adverse cardiovascular events. [1][3] Complications may include low blood pressure and cardiac arrest. [1][5] It is typically caused by kidney failure or is treatment-induced such as from antacids or ...
