21 MODULE SIXTEEN Cardiac Scenarios Scenario One A 72 year old woman who is on the ward with a chest infection has started to complain to you that she has chest pain. The pain is centralised and crushing in nature. The pain is also radiating down the left arm. She is clammy to the touch and is complaining of feeling nauseous. On examination her blood pressure is 100/56, Pulse 100, Temperature 36.4 C and the pain is 8 out of 10. An ECG is taken showing T Wave flattening in leads V3, V4, V5 and V6. What would you suspect?

On examination it is noted that his pulse has become fast, with a rate of 110 Bpm and irregular. His Blood pressure has dropped from 146/73 to 105/50. An ECG is taken showing an irregular fast pulse with no P waves present. What is the possible new diagnosis for this patient? What would the treatment be for this patient? What would the blood test would you carry out? Scenario Three A 48 year old man is admitted with renal failure. On a routine ECG he is noted to have peaked T waves. What could this signify?

23 What tests would you undertake to confirm diagnosis? What would the treatment be for this patient? Scenario Four A 77 year old female arrives in A&E with increased SOB (worse when lying flat), pedal oedema (Grade 3) and an elevated JVP (+4cm). A chest x ray is taken showing cardiomegaly and Kerley s lines. She is also noted to be in atrial fibrillation and has a BNP of 900. A recent history taken shows she has had a number of heart attacks over the past two years. What condition is this patient most lightly to have? What is the gold standard test to confirm this?

24 What would the treatment be for this patient?
