However, before you accept that everything is fine, there are some basic questions that need to be asked.
Do you have any symptoms when your heart rate is slower than usual?
Call your doctor if you have chest pain, shortness of breath or lightheadedness with a slow heartbeat.
If the answer is yes, that is very reassuring. If it feels like it is skipping around, you may have a mild arrhythmia. Usually this won't need any special treatment. But you should get an electrocardiogram to identify the type of arrhythmia. Are you taking a beta blocker or calcium channel blocker?
These drugs slow the heart rate and a rate of 50 to 59 is fine. Sometimes doctors want the heart rate to stay in that range. Do you have more fatigue than usual?
A slow heart rate can be a sign of an under active thyroid (called hypothyroidism). Hypothyroidism in females is quite common. A simple blood test can determine if you have it.
