In brief: Common

It's surprisingly common and can occur in normal hearts in the absence of heart disease.
It can be caused by cardiac stimulants like caffeine, nicotine, amphetamine, alcohol, and certain medicines like bronchodilators, atropine, and adrenalin. Thyroid excess can cause it. Stress and lack of sleep can contribute. It occurs for no recognized reason in some.
