- confined to the lower extremities, as in pedal edema
- respiratory in nature (e.g., dyspnea, orthopnea)
- relieved by morphine
- cured by an antibiotic
3. sympathetic stimulation to the heart:
- decreases stroke volume
- increases heart rate
- decreases cardiac output
- causes bradycardia
4. the atrioventricular node (AV node):
- delays the electrical signal coming from the atria into the ventricles
- is the pacemaker of the heart
- has a rate that is normally faster than the SA node
- is located in the upper part of the right atrium
5. which of the following best indicates why the left ventricular myocardium is thicker than the right ventricular myocardium?
- the left ventricular works harder than the right
- the aortic valve is narrower than the pulmonic valve
- left ventricular oxygen saturation is greater in the left ventricular
- left ventricular volume is less that the right ventricular volume
