Slow heart rate does not increase risk of heart disease

Bradycardia -- a slower than normal heartbeat -- does not increase the risk of developing cardiovascular disease, according to a study. The heart usually beats between 60 and 100 times a minute in an adult at rest. But with bradycardia, the heart beats fewer than 50 times a minute. The condition can cause light-headedness, shortness of breath, fainting or chest pain due to the heart not pumping enough oxygen-rich blood through the body.
