I've noticed my heart rate has been pretty low for the past couple of days, like around 55 beats per minute when I'm just resting or sleeping. Should I be worried about this, or is it normal?

Slow heart rate can be concerning, especially if it persists for a few days. A heart rate of 55 beats per minute or above at rest or during sleeping time may indicate bradycardia. It is important to identify the underlying cause of this slow heart rate. Some common causes of bradycardia include medication side effects, electrolyte imbalances, heart disease, or an underactive thyroid gland. If you are experiencing symptoms such as dizziness, fainting, chest pain, or shortness of breath along with the slow heart rate, it is important to seek medical attention promptly. Your doctor may recommend further evaluation, which may include an electrocardiogram (ECG) or other tests to determine the cause of the bradycardia. In some cases, medication may be prescribed to help regulate the heart rate. However, the specific treatment will depend on the underlying cause of the slow heart rate. It is important to follow up with your healthcare provider for a proper evaluation and management plan.
