9. Syncope
Syncope is the medical term for loss of consciousness or fainting. The person is typically unconscious for a very short period. Both bradycardia and tachycardia can cause syncope, which results from insufficient blood flow to the brain.
Dizziness or lightheadedness often accompany fainting spells caused by an irregular heartbeat. With bouts of arrhythmia, the drop in blood pressure is often very severe and abrupt. This leads to the sudden loss of consciousness, and medical intervention should occur.
