Chest pain lasting only a few seconds is normally not angina (such as precordial catch syndrome). Myocardial ischemia comes about when the myocardium (the heart muscle) receives insufficient blood and oxygen to function normally either because of increased oxygen demand by the myocardium or because of decreased supply to the myocardium.
[2] [4] If this is insufficient for treating vasovagal syncope, medications such as midodrine or fludrocortisone may be tried. [4] Occasionally, a cardiac pacemaker may be used as treatment. [2] Reflex syncope affects at least 1 in 1,000 people per year. [1] It is the most common type of syncope, making up more than 50% of all cases. [2]

Blood circulation can be stopped in the entire body below the heart for at least 30 minutes, with injury to the spinal cord being a limiting factor.

The symptoms usually begin within 30 minutes of ejaculation, [5] and can last for several days, sometimes up to a week. [4] In some cases, symptoms may be delayed by 2 to 3 days or may last up to 2 weeks. [9] In some men, the onset of POIS is in puberty, while in others, the onset is later in life. [10]
