2

Outpatient Cardiology Clinic

In this interactive session, you are a final year medical student on their Cardiology rotation. You are attached to the outpatient Cardiology clinic. You have been asked to see some of the patients from the clinic list independantly and to present your findings after review.

Slide image

You double check the list before calling in your first patient...

4

Mr John Zenon

  • An 85-year-old man presenting with fatigue and episodes during which he feels he is going to pass out. He has no known heart disease. 

  • An ECG was requested and the nurse attached this to his file.

5

Interpret this ECG...

6

Multiple Choice

Question image

What does the ECG demonstrate?

1

Atrial fibrillation

2

Normal sinus rhythm

3

Sinus bradycardia

4

First degree heart block

7

Sinus bradycardia

  • HR <50/60bpm, even if transient

  • Sinus node dysfunction or conduction system disease

  • Causes - intrinsic sinus node, AV nodal, and His-Purkinje disease, or extrinsic influences

  • Symptoms - syncope, fatigue, and dizziness

  • Complications - cardiovascular collapse and death

Slide image

8

Fill in the Blank

In haemodynamically unstable patients with sinus bradycardia, ________ is the drug of choice for treatment.

9

Atropine

Muscarinic antagonist

Increases ventricular rate

Used in severe bradycardia or heart block


10

Mr Dennis Kyalo

  • A 78-year-old man with a history of hypertension presents to his primary care physician with 1 episode of dizziness while watching television. On physical examination, his heart rate is measured at about 40 bpm.

  • A 12-lead ECG is obtained.

Multiple Choice

Question image

What does the ECG demonstrate?

1

Sinus bradycardia

2

Atrial fibrillation

3

2:1 heart block

4

Complete heart block

13

Complete heart block

  • Impaired (delayed or absent) conduction from the atria to the ventricles

  • Causes -  fibrosis and calcification of the conduction system, CAD, and medication

  • Symptoms - syncope/pre-syncope, fatigue, dyspnoea

  • Permanent pacing improves survival in patients with third-degree AV block, especially if syncope has occurred

14

Open Ended

Can you name a drug that can cause heart block?

15

Side effects may include...

  • beta-blocker - glucagon

  • calcium channel blocker - calcium chloride

  • digoxin - digibind (digoxin immune Fab)

16

Mrs Sara Valerio

  • A 30-year-old woman complaining of recurrent palpitations during exercise. She had previously been healthy and was on no medications. She described a long history of 'skipped heart beats'.

  • She attends the clinic for a treadmill exercise test, which demonstrated good effort tolerance and no evidence of ischaemia.

  • Mrs Opoku then collapses in the recovery area and the emergency alarm is pulled.

18

Multiple Choice

Question image

What does the ECG demonstrate?

1

Pulseless electrical activity (PEA)

2

Ventricular fibrillation

3

Ventricular tachycardia

4

Torsades de pointes

19

VT (Monophasic)

  • Ventricular rhythm faster than 100 bpm

  • Causes - ischaemic heart disease, structural heart disease, idiopathic

  • RVOT tachycardia - stress, exercise, catecholamine excess

  • Symptoms - tachycardia, hypotension, syncope, airway compromise

  • Complications - VF, sudden cardiac death

22

Mr Juan Doe

  • A 35-year-old man previously presented to accident and emergency department with palpitations, shortness of breath, dizziness, and chest pain of 4 hours' duration.

  • His symptoms self-resolved and he was referred to the Cardiology clinic for further assessment.

23

24

Multiple Choice

Question image

What does the ECG demonstrate?

1

NSTEMI

2

Right bundle branch block

3

Atrioventricular Reentry Tachycardia

4

Wolff-Parkinson-White Syndrome

25

Wolff-Parkinson-White Syndrome

  • Accessory pathway from the atrium to the ipsilateral ventricle across the mitral or tricuspid annulus - pre-excite the ventricle

  • Causes - Defect in the atrioventricular (AV) electrical insulation 

  • Symptoms - palpitations, dizziness, SOB, chest pain

  • Complications - sudden cardiac death

Slide image

26

Fill in the Blank

The features of pre-excitation may be subtle, or present only intermittently. Pre-excitation may be more pronounced during ________ manoeuvres.

27

Valsalva Maneuver

Increase vagal tone

Increase intrathoracic pressure

Reduce preload

Reduce heart rate

Diagnose pre-excitation

Can be used to terminate SVT

28

Mr Horacio Lopez-Garcia

  • A 50-year-old man presents to the emergency department and referred to cardiology clinic with worsening left-sided chest pain for 2 days. The pain is worse on taking a deep breath. He describes shortness of breath due to the pain. His examination is unremarkable except for tenderness on palpation of the left fourth and fifth costochondral joints.

29

Open Ended

What is the most common condition in patients presenting with chest pain to the emergency department?

30

Costochondritis

  • Inflammation of ≥1 costal cartilages

  • Causes - idiopathic, repetitive microtrauma, infective

  • Symptoms - Insidious onset of anterior chest-wall pain exacerbated by certain movements of the chest and deep inspiration

  • Treatment - NSAIDS (+PPI), surgical drainage or debridement
