difference between action potential of sa node and contractile myocytes
Different groups of cells depolarize at different rates. The rate of depolarization of SA node cells is faster than the rate of depolarization of AV node cells. ... If both the SA node and AV node fail, the Purkinje fibers have a modest level of automaticity (20 beats/minute) that may still reach threshold

Answer:
The correct answer is a and b( exceed 135 mg/dl and can only be controlled through medications.)
Explanation:
Cholesterol is a natural fatty substance that is present in the body and is necessary for the proper functioning of the cells of the human body. It is considered to be at the high limit when the whole blood level exceeds 130 milligrams per deciliter of blood (mg / dl). When this happens, fats tend to build up inside the arteries, impeding blood flow and can lead to serious heart disease and stroke. A doctor usually prescribes drugs to lower high cholesterol (they usually recommend statins), it is because the person is in the intermediate risk limit and has factors that increase the risk of heart disease or stroke, causing long-term arteries become clogged and diseases such as atherosclerosis or heart attack appear.
