What is sinus rate below 60bpm?

Sinus rate below 60 bpm is called bradycardia. Bradycardia can be caused by a number of factors, including:

* Heart disease: Bradycardia can be a sign of heart disease, such as coronary artery disease, heart failure, or valvular heart disease.

* Hypothyroidism: Bradycardia can also be caused by hypothyroidism, a condition in which the thyroid gland does not produce enough thyroid hormone.

* Medications: Certain medications, such as beta-blockers, calcium channel blockers, and digoxin, can cause bradycardia.

* Other medical conditions: Bradycardia can also be caused by other medical conditions, such as diabetes, kidney disease, and liver disease.

Bradycardia can be a serious condition, but it is often treatable. Treatment depends on the underlying cause of the bradycardia.
