Question: My normal heart rate is 110 to 120. I am a woman who is 56. Should I be concerned?

Dr. Hibberd's answer:
For an adult, a normal resting heart rate ranges from 60 to 100 beats a minute. Although there's a wide range of normal, an unusually high or low heart rate may indicate an underlying problem. Consult your doctor if your resting heart rate is consistently above 100 beats a minute (tachycardia) or below 60 beats a minute (bradycardia) and especially if you have other signs or symptoms, such as fainting, dizziness, or shortness of breath.
