Question 1

Your buddy nurse asks for an ECG. Explain the rationale for the ECG request (5 marks). Why would the nurse also ask you to prepare for a blood test? (2 marks) Why do both ECG and a blood test? (3 marks)

Question 2 
The medical team confirm the diagnosis of heart failure. Describe the pathophysiology of heart failure with reference to causes, progression and outcomes. Include links to how heart failure has progressed for Deep.

Question 3
Appendix 1 is an ECG that was taken while Deep was experiencing shortness of breath. Systematically analyse the ECG, commenting on the:
– Rhythm
– Rate
– Presence and regularity of p waves
– ST segment

What is your interpretation of this ECG?

Question 4 
Deep became short of breath overnight during admission. Discuss the physiology as to why this occurred. What two things has Deep been doing that would exacerbate his heart failure, with explanation?
