Location: You are an FY1 in out patient clinic, you have been asked by your consultant to perform a full cardiovascular examination for an admission clerking

Patient: 78 year old presenting to out patient clinic

Task:
– Examine this patients cardiovascular system
– Talk through your examination whilst examining, stating any key positives and negatives
– After 6 minutes you will be asked a series of questions by the examiner

Note to actor: Try to restrain yourself from volunteering to much information – you may do so when prompted (that is, by a specific question, not a general one). If a student is on the wrong line of clinical reasoning do not fuel this line of thinking, state no to the question as being ambiguous may prompt further questioning and does not allow the student to be appropriately tested. The aim of the exercise is to take a focused history; short answers are required.

You are a 78 year old patient who has attended out patient clinic. You are happy to be examined by the junior doctor.

Abnormal findings: irregularly irregular pulse, HR 92. No other abnormal findings

BP = 125/70

At 6 minuets the candidate will be asked some questions by the examiner.

Category Question

Pulses Examines for pulses
Radial pulse – if asked examiner states " Radial pulse is irregularly irregular"

Inspection Closer inspection for
Presence of pacemaker
Midline sternotomy
Vein harvesting scar on legs


Palpation Palpation for
Apex beat – 5th intercostal space, midclavicular line
Heaves
Thrills


Auscultation Auscultation, examiner prompt: “please explain to me the anatomical landmarks you are using as you examine the patient”
Auscultates whilst palpating carotid pulse
Aortic region (2nd right intercostal space)
Pulmonary region (2nd left intercostal space)
Tricuspid region (Left lower sternal edge i.e 4/5th intercostal space)
Apex region (Left 5th intercostal space mid-clavicular line)
Examines all 4 regions with both bell and diaphragm


Auscultation extended Auscultation heart sounds extended
Carotid pulse auscultation, held at end expiration
Patient rolled onto left hand side, listening over apex, at expiration
Patient sitting forwards, leaning forwards, at expiration


Auscultation extra-precordium
Auscultation of lung bases
Checks for sacral oedema
Checks for calf tenderness and pitting oedema


Finishing Finishing remarks
Invites patient to dress again
Re-washes hands
Offers to view observation chart (including BP, HR, O2 sat and T)


Question
This is the patients ECG. Comment on the key findings and give a most likely diagnosis

Irregularly irregular rhythm
Absence of P waves
Absence of an isoelectric baseline
Variable ventricular rate
Most likely diagnosis – atrial fibrillation


Question What are the causes of atrial fibrillation?
Ischaemic heart disease
Thyrotoxicosis
Pneumonia / urosepsis
Rheumatic heart disease
Pulmonary embolus
Alcohol


Question What are the differentials for an irregularly irregular pulse?
Atrial fibrillation
Ventricular ectopic beats
Complete heart blocks with variable ventricular escapes


Question What scoring system is used to assess the risk of stroke for a patient in atrial fibrillation?
CHA2DS2VASc
