Carotid sinus syncope is due to pressure on the carotid sinus in the neck. [2] The underlying mechanism involves the nervous system slowing the heart rate and dilating blood vessels, resulting in low blood pressure and thus not enough blood flow to the brain. [2] Diagnosis is based on the symptoms after ruling out other possible causes. [3]
Treatment for narcolepsy and cataplexy can be divided to those that act on the excessive daytime sleepiness (EDS) and those that improve cataplexy. Most patients require lifelong use of medications. [15] Most treatments in humans will act only symptomatically and do not target the loss of the orexin-producing neurons. [16]
Since a stress response can increase your heart rate and blood pressure, chronic stress can lead to long-term cardiovascular problems such as: Heart attack Stroke
Low blood pressure and a fast heart rate after the event may indicate blood loss or dehydration, while low blood oxygen levels may be seen following the event in those with pulmonary embolism. [1] Routine broad panel laboratory testing detects abnormalities in <2–3% of results and is therefore not recommended.
Elevated blood pressure is a systolic pressure of 120-129 mm Hg, and a diastolic pressure of less than 80 mm Hg. High blood pressure Stage 1 is defined as 130-139 over 80-89 mm Hg. What does high ...
A blood choke disrupts blood circulation to the brain, while an air choke disrupts breathing. Blood chokes can be applied to efficiently cause loss of consciousness, i.e. a choke-out, while air chokes do not usually cause loss of consciousness without prolonged application (though air chokes are used to cause discomfort).
Cialis has an impressively long half-life — one dose can last up to 36 hours (hence, its nickname “the weekend pill”). ... Does Cialis raise blood pressure? As a vasodilator, tadalafil is ...
Continued oxygen deprivation results in fainting, long-term loss of consciousness, coma, seizures, cessation of brain stem reflexes, and brain death. [7] Objective measurements of the severity of cerebral hypoxia depend on the cause. Blood oxygen saturation may be used for hypoxic hypoxia, but is generally meaningless in other forms of hypoxia ...
