Are Heart Arrhythmias Dangerous?

If you're over 40 keep reading

Approximately one in 18 people, or 5 percent of the U.S. population, has an arrhythmia. A recent study has also suggested that one in four adult Americans over the age of 40 could develop an irregular heartbeat.

Arrhythmias can affect anyone—even people who are otherwise healthy and free of other forms of heart disease. Things that can cause the heart to beat abnormally include heavy smoking, alcohol use, excess caffeine or other stimulants, stress, thyroid disease, and fever.

Arrhythmias may be completely harmless, or they can be life-threatening. Some arrhythmias are very brief and don’t affect your overall heart rhythm. But if arrhythmias last longer, they may cause your heart rate to be too slow, too fast or erratic, causing the heart to pump less effectively.
