Sémiologie | Résumé " les signes fonctionnels en cardiologie " - cours de 3 ème année médecine

Introduction

This tutorial summarizes the key functional signs in cardiology, focusing on four primary symptoms: pain, dyspnea, palpitations, and loss of consciousness. Understanding these signs is essential for medical students and healthcare professionals as they are critical for diagnosing cardiovascular issues.

Step 1: Recognizing Pain

• Types of Pain:
  • Chest pain is the most common symptom in cardiology.
  • Differentiate between sharp, dull, or pressure-like sensations.
• Key Questions:
  • Where is the pain located?
  • Does it radiate to other areas (e.g., arms, jaw)?
  • What triggers or alleviates the pain?
• Common Causes:
  • Angina
  • Myocardial infarction (heart attack)

Tip: Always consider the patient's history and risk factors when assessing chest pain.

Step 2: Identifying Dyspnea

• Definition: Dyspnea refers to shortness of breath or difficulty breathing.
• Types:
  • Exertional dyspnea occurs during physical activity.
  • Orthopnea occurs when lying flat.
  • Paroxysmal nocturnal dyspnea wakes the patient from sleep.
• Assessment:
  • Ask about the onset, duration, and frequency of dyspnea.
  • Evaluate any associated symptoms like chest pain or cough.

Common Pitfall: Do not overlook anxiety or panic attacks as potential causes of dyspnea.

Step 3: Evaluating Palpitations

• Definition: Palpitations are sensations of a racing, fluttering, or pounding heart.
• Questions to Ask:
  • When do they occur, and how long do they last?
  • Is there any associated dizziness or chest pain?
• Potential Causes:
  • Arrhythmias
  • Anxiety
  • Caffeine or stimulant use

Practical Tip: Keeping a diary of palpitations can help identify triggers and patterns.

Step 4: Assessing Loss of Consciousness

• Definition: Loss of consciousness can range from fainting (syncope) to complete unresponsiveness.
• Key Considerations:
  • What were the circumstances surrounding the loss of consciousness?
  • Has the patient experienced any similar episodes before?
• Important Causes:
  • Cardiac arrhythmias
  • Hypotension
  • Neurological issues

Tip: Always consider a comprehensive history and physical examination to rule out serious conditions.

Conclusion

Understanding and recognizing these four functional signs—pain, dyspnea, palpitations, and loss of consciousness—are vital for effective cardiology assessments.
