Patient’s Story (Role-Player Brief)

You are David Miller. You’ve booked an urgent telephone call because you’ve been feeling unwell for the last 24-36 hours.

• Presenting Complaint: You’ve had episodes of your heart “fluttering” or “racing” in your chest. It feels irregular, like it’s “all over the place.” This has happened 3-4 times, each lasting 20-30 minutes. During these episodes, you feel a bit dizzy and slightly short of breath, which makes you anxious. You are not having an episode right now, but you still feel tired and “not right.”
• Key Information (Reveal only on direct questioning):
  • You had a bad chesty cold with a cough last week, but it’s mostly better now.
  • You drink about 2-3 pints of beer most evenings to “wind down.”
  • You have no chest pain or history of heart problems, other than high blood pressure.
  • You haven’t fainted or collapsed.
  • You have not had any weakness in your arms/legs or problems with your speech.
• ICE (Ideas, Concerns, Expectations):
  • Ideas: “I think it’s just stress. I’ve had a lot on my plate, and maybe the cold I had has just left me feeling run down.”
  • Concerns: “My biggest worry is my HGV licence. I heard that heart problems mean you get your licence taken away. If I can’t drive, I lose my job. My whole life is on the road.”
  • Expectations: “I was hoping for something to calm my nerves, maybe some anxiety tablets. I just want to get back to work tomorrow.”
• Psychosocial Context: You are a long-distance lorry driver and the sole earner for your household. The thought of not being able to drive is terrifying for you. Your wife is at home and relies on you.
• Role-Play Instructions:
  • Initially, downplay the symptoms as “just a bit of a flutter.”
  • If the doctor suggests hospital admission, strongly resist at first. Emphasise your need to work and your fears about your licence. Say things like, “Isn’t there just a pill you can give me?” or “Hospital sounds a bit extreme, I feel fine now.”
  • Only agree to the referral if the doctor clearly and empathetically explains the risks (especially stroke) and the reasons for the urgent assessment.

Data Gathering & Diagnosis

Phase 1: Open the Consultation & Explore the Presenting Complaint Rationale: To build rapport and gain a deep, patient-centered understanding of the primary issue before narrowing down.

• Key Questions:
  • “Tell me more about this ‘fluttering’ feeling in your chest.”
  • “When did the first episode happen?” (Confirms onset <48 hours).
  • “Can you describe what the heartbeat feels like? Is it fast, slow, regular, or irregular?”
  • (SOCRATES): “When you have these episodes, do you feel any chest pain, dizziness, shortness of breath, or feel like you might pass out?” (Assesses haemodynamic stability).
  • “How long does an episode last, and how many have you had?”

Phase 2: Broaden the Differential & Screen for Red Flags Rationale: To ensure patient safety by actively ruling out ‘cannot miss’ diagnoses (Stroke, ACS, Heart Failure) while exploring common and important differentials to build a complete clinical picture.

• Key Questions:
  • Cardiovascular Red Flags: “Have you had any severe chest pain, like a pressure or tightness?” (Rules out ACS). “Have you actually fainted or lost consciousness?” (Rules out syncope/severe haemodynamic instability). “Is the breathlessness severe, or does it happen when you’re lying flat?” (Screens for acute heart failure).
  • Neurological Red Flags (Stroke/TIA): “Have you noticed any weakness in your face, arms, or legs, even for a short time?” “Any slurred speech or difficulty finding your words?” (Crucial for ruling out a major complication of AF).
  • Screen for Reversible Triggers: “Have you had any fever, cough, or phlegm recently?” (Screens for pneumonia). “Have you been feeling unusually hot, sweaty, or have you lost any weight without trying?” (Screens for thyrotoxicosis).
  • Screen for Other Differentials: “Do these episodes come with a sense of panic or overwhelming fear?” (Considers anxiety/panic attack).

Phase 3: Build the Clinical Context Rationale: To place the symptom in the context of the patient’s overall health and identify contributing factors or important comorbidities for risk stratification.

• Key Questions:
  • Relevant Medical History (CHA₂DS₂-VASc components): “I can see you have high blood pressure and diabetes. Have you ever been told you have heart failure, or had a stroke or mini-stroke in the past?” “Any problems with the circulation in your legs?” (Checks for vascular disease).
  • Medication History: “Are you taking your Ramipril regularly?” “Do you take any other medications, including anything over-the-counter like aspirin or ibuprofen?” (Relevant for bleeding risk/ORBIT score).
  • Family History: “Is there any history of heart rhythm problems or sudden death in your close family?”

Phase 4: Understand the Patient’s Perspective & Impact Rationale: To conduct a holistic, patient-centered consultation by understanding the person behind the symptoms. This is crucial for shared decision-making and overcoming barriers to management.

• Key Questions:
  • ICE: “What are your thoughts on what might be causing this?”, “What is your main worry about all this?”, and “What were you hoping we could do for you today?”.
  • Impact on Life/Occupation: “What kind of work do you do?” “Does your job involve driving?” (This is the critical psychosocial element of the case).
  • Lifestyle: “How much alcohol would you say you drink in a typical week?” (Alcohol is a key reversible factor and also a component of the ORBIT score). Ask about smoking and caffeine.

Working Diagnosis:

• Most Likely: New-onset Atrial Fibrillation (<48 hours), likely haemodynamically stable.
• Important Differentials: Paroxysmal supraventricular tachycardia (SVT), Anxiety/Panic Disorder.

Diagnosis & Explanation Script

“David, thank you for explaining all that so clearly. I know you’re thinking this might be stress, but the irregular, racing heartbeat you’re describing, along with the dizziness, makes me concerned you might have a heart rhythm problem called Atrial Fibrillation, or AF. It’s where the top chambers of the heart beat irregularly. The main reason we need to take this seriously is that AF significantly increases the risk of having a stroke. I understand your biggest worry is your driving licence, and we will absolutely talk about that, but my priority right now is to ensure we get this properly diagnosed and treated to keep you safe.”

Management

1. Address ICE & Agree on Goals:

• “David, I’ve heard loud and clear that your biggest concern is your HGV licence and your job. I understand completely. Our goal today is to get a definite diagnosis and start the right treatment quickly. Making sure your heart is safe is the very first step in being able to make a clear plan for your work and your licence.”

2. Offer and Explain Investigations & Referrals:

• Referral (Urgent, Same-Day): “Because this has started in the last day or so and your heart is showing these signs, I need you to go to the hospital today to be seen by the cardiology assessment team. This isn’t something that can wait. I will call them now to let them know you are coming.”
• Rationale: “At the hospital, they will do an ECG, which is a simple tracing of your heart’s electrical activity. This is the only way to confirm if it is AF. They will also do some blood tests and check you over fully. This is the standard and safest approach for anyone with new symptoms like yours.”

3. Collaborative Treatment Planning (Medication & Lifestyle):

• Immediate Plan: “The immediate plan is the hospital assessment. You should not take any new medication until they have seen you.”
• Explain Hospital Plan: “The specialists at the hospital will discuss two main things with you: first, a plan to control the rate or rhythm of your heart, and second, starting a blood-thinning medication. Blood thinners are essential in AF to dramatically reduce the risk of a stroke.”
• Show relevant drug structures: Anticoagulants are a key part of AF management. Direct-acting oral anticoagulants (DOACs) like apixaban and rivaroxaban are first-line, with warfarin as an alternative. Rate control may involve beta-blockers like bisoprolol or calcium channel blockers like verapamil.

4. Explicit Safety Netting & Contingency Planning:

• Driving: “Crucially, you must not drive until the specialists have seen you and given you clear advice. I know this is the toughest part to hear, but a sudden dizzy spell or a flutter while you’re behind the wheel of a lorry would be catastrophic. Your safety, and the safety of others, comes first. The DVLA has strict rules about this, and we must follow them.”
• Urgent Symptoms: “While you are waiting to go to the hospital, if you experience any severe chest pain, become very short of breath, feel like you are about to pass out, or notice any weakness in your face or limbs, or slurred speech, you must call 999 immediately. Do not wait.”

5. Summarise, Check Understanding & Agree on Follow-Up:

• Summary: “So, just to recap the plan: I am calling the cardiology team at the hospital now for you to be seen today. You must not drive there. The most important thing is to get that ECG to confirm the diagnosis. Does that plan make sense?”
• Follow-up: “Once the hospital has seen you and made a plan, please book a follow-up appointment with me to discuss their findings and the next steps for managing this and for discussing the DVLA implications for your licence.”
