While primary problems to your heart, such as an abnormality in the heart’s electrical circuitry, always need to be considered, these conditions are usually most likely to occur in the presence of other symptoms such as light-headedness, blackout episodes, and shortness of breath. Sometimes, a family history of heart-related problems, including an unexpected death in a close relative, can aid in making such a diagnosis.
Thus, as you can see, multiple factors may explain why your heart rate seems high. As an individual who is unique, however, your resting heart rate and heart rate response to exercise may be entirely appropriate and normal for you. Regardless of the cause, it is important to raise this issue with your own doctor. Almost all of the causes of a fast resting heart rate are treated and reversible once the root causes are appropriately identified.
