The most common cause of cardiac syncope is cardiac arrhythmia (abnormal heart rhythm) wherein the heart beats too slowly, too rapidly, or too irregularly to pump enough blood to the brain. [9] Some arrhythmias can be life-threatening. [9] Two major groups of arrhythmias are bradycardia and tachycardia. Bradycardia can be caused by heart blocks.
Reflex syncope can occur in otherwise healthy individuals, and has many possible causes, often trivial ones such as prolonged standing with the legs locked. [ citation needed ] The main danger of vasovagal syncope (or dizzy spells from vertigo) is the risk of injury by falling while unconscious.
The risks of developing a life-threatening disease affecting the heart or brain increase as the blood flow increases. Commonly, ischemic heart attack and stroke are the causes that lead to death in patients with severe hypertension.
Fainting while remaining vertical increases the risk of death from cerebral hypoxia. [1] Since there is no evidence that these effects are specifically due to trauma, or caused by the harness itself, climbing medicine authorities have argued against the terminology of suspension trauma or harness hang syndrome and instead termed this simply ...
Heat syncope is fainting or dizziness as a result of overheating (syncope is the medical term for fainting). It is a type of heat illness.

The diagnosis of a breath-holding spell is made clinically. A good history including the sequence of events, lack of incontinence and no postictal phase, help to make an accurate diagnosis. Some families are advised to make a video recording of the events to aid diagnosis. An electrocardiogram (ECG) may rule out cardiac arrhythmia as a cause. [1]
