Draw and label a left ventricular pressure volume loop in a normal adult (40% of marks). List the information that can be obtained from this loop (60% of marks).
Many candidates lost marks for poor quality diagrams with inaccurate labelling. An accurate diagram was required. Many answers lacked sufficient detail regarding contractility and afterload.
If a trainee had failed this question and were looking for an answer as to how and why they failed, the remark that "an accurate diagram was required" would be uninformative. This examiner comment in general leaves much to be desired. Fortunately, this SAQ was plagiarised verbatim from Question 12(p.2) from the first paper of 2008, and that time, the examiners did write something useful in their response. On the basis of their comments, it was possible to fashion this answer:
