A 60 year-old patient HA, who was bedridden for a few days, feels dizzy and experiences significant increase in his heart rate after standing up. If this patient is regularly taking Angiotensin Converting Enzyme (ACE) inhibitor, such as lisinopril, how will this drug affect his sympathetic discharge to the heart, to veins and to arterioles? What changes in his blood pressure can be expected? What advice should be given to this patient?

Vern, suffering from cardiac arrhythmias, is brought into the emergency room of a hospital. The doctors hook him up to an ECG. He begins to exhibit a decreased R to R interval, and as a result loses consciousness. His anxious partner asks you why he has lost consciousness. a.How would you respond? What is wrong with him, and why did it cause a loss of consciousness. The partner then responds that Vern took nitroglycerine because he was experiencing chest pain known as angina. One of the major side effects of the medication is that the patient will notice a severe headache. b. What does nitroglycerine do? c. How is it administered? d.How does it distribute through the body? e.What is the target cell and mechanism of action on the heart? f. What causes the headache? g.Could the drug have caused the arrhythmia?
