Types and differences for syncope

1. Neurocardiogenic (syncope vasovagal syncope & vasodepressor syncope): half of all episodes of fainting.
   Caused by abnormalities in the autonomic nervous system, which controls the heart rate and circulation. vasovagal syncope is caused by both widening of the arteries and bradycardia, while vasodepressor syncope is caused by widening of the arteries alone.

2. Orthostatic syncope: Caused by rising rapidly from a reclined position, 30% in elderly

3. Carotid sinus syncope (carotid sinus syndrome): Caused by a sudden loss of consciousness due to compression of the carotid sinus. It can be caused by turning the head to one side or wearing clothing or jewelry too tight on the neck.

4. Situational syncope: Number of normal activities; urinating, coughing, swallowing and defecating, etc. it can be both vasodepressor syncope and vasovagal syncope.Conditions associated with situational syncope include lung diseases, BPH, bladder obstruction, esophageal disorders and constipation.

5. Cardiac syncope: Caused by a sudden reduction in cardiac output Patient with cerebrovascular disease, anemia, coronary artery disease or heart valve disease are prone.

6. Idiopathic syncope: In most of these cases, the syncope is a singular episode from which the patient recovers quickly and suffers no long-term damage.
