Syncope, also known as fainting, is a loss of consciousness and muscle strength characterized by a fast onset, short duration, and spontaneous recovery. It is primarily caused by a decrease in blood flow to the brain, typically from low blood pressure.
Symptoms[edit | edit source]
Prior to the loss of consciousness, symptoms may include lightheadedness, sweating, pale skin, blurred vision, nausea, vomiting, or feeling warm. Syncope may also be associated with a short episode of muscle twitching.
Presyncope[edit | edit source]
When consciousness and muscle strength are not completely lost, the condition is called presyncope. Despite the less severe symptoms, it is recommended that presyncope be treated the same as syncope due to the similar underlying causes[1].
Causes[edit | edit source]
The main cause of syncope is a decrease in blood flow to the brain. This can be due to a sudden drop in blood pressure, a severe irregular heart rhythm, or changes in blood volume or distribution. Certain conditions can also trigger syncope, such as standing for long periods, dehydration, or being in a hot environment.
Diagnosis[edit | edit source]
The diagnosis of syncope begins with a detailed medical history and physical examination. Further tests, such as an electrocardiogram (ECG), echocardiogram, or tilt table test, may be required to identify the underlying cause.
Treatment[edit | edit source]
The treatment of syncope focuses on addressing the underlying cause. This could include medications, dietary changes, use of compression stockings, or in some cases, pacemaker or defibrillator implantation.
