-- is a sign there is a problem with the heart's electrical system. It means that the heart's natural pacemaker isn't working right or that the electrical pathways of the heart are disrupted. In severe forms of bradycardia, the heart beats so slowly that it doesn't pump enough blood to meet the body's needs. This can cause symptoms and can be life-threatening.

- a rhythm in which the rate of impulses arising from the sinoatrial (SA) node is lower than expected.
--severe=less than 40

-heart beating so slow it's not reperfusing organs

-Age-related reasons:
--HR decreases w/ age

-also caused by diseases (CAD, thyroid disease etc.), different conditions
-some caused by high BP, antiarrythimics

-Sinus bradycardia is a rhythm in which the rate of impulses arising from the sinoatrial (SA) node is lower than expected.
-severe=less than 40

-heart beating so slow it's not reperfusing organs

-Age-related reasons:
--HR decreases w/ age

-also caused by diseases (CAD, thyroid disease etc.), different conditions
-some caused by high BP, antiarrythimics\

-Changes in the heart related to aging.

-Diseases that damage the heart's electrical system. These include coronary artery disease, heart attack, and infections such as endocarditis and myocarditis.

-Conditions that can slow electrical impulses through the heart. Examples include having a low thyroid level (hypothyroidism) or an electrolyte imbalance, such as too much potassium in the blood.

-Some medicines for treating heart problems or high blood pressure, such as beta-blockers, antiarrhythmic, and Digoxin.
