Due to increase size in muscle cells & myositis: slowing of electrical activity, slowed pulse: bradycardia, fat tissue surrounds the senatorial node, increased blood pressure, decreased ability to cool down or heat up. Systolic pressure is peak pressure in the arteries, which occurs near the beginning of the cardiac cycle when the ventricles are contracting. Diastolic pressure is minimum pressure in the arteries, which occurs near the end of the cardiac cycle when the ventricles are filled with blood. Systolic hypertension increases through life, whereas an elevation in diastolic pressure tends to level off in later years.
