Differential Diagnosis for a 42F with Pacemaker and Hx of Afib with Chest Pain

Single Most Likely Diagnosis

  • Pacemaker-related issue or malfunction: Given the patient's history of a pacemaker and atrial fibrillation (Afib), a pacemaker-related issue could be causing the chest pain, especially if the pacemaker is not functioning correctly or if there are issues with the leads.

Other Likely Diagnoses

  • Anxiety or stress-related chest pain: Patients with a history of Afib and a pacemaker may experience anxiety or stress, which can manifest as chest pain.
  • Musculoskeletal chest pain: This is a common cause of chest pain in the general population and could be considered in this patient, especially if there are no other concerning symptoms.
  • Pericarditis: Although less common, pericarditis can cause chest pain and is a consideration in patients with a history of cardiac conditions.

Do Not Miss Diagnoses

  • Myocardial Infarction (MI): Although the patient is hemodynamically stable and has a paced rhythm, MI is a critical diagnosis that must not be missed, especially in patients with a history of Afib, which increases the risk of thromboembolic events.
  • Pulmonary Embolism (PE): Given the patient's history of Afib, there is an increased risk of thromboembolic events, including PE, which can cause chest pain.
  • Aortic Dissection: This is a life-threatening condition that requires immediate diagnosis and treatment. Although less common, it is a critical consideration in patients presenting with chest pain.

Rare Diagnoses

  • Pneumothorax: Although rare, pneumothorax can cause chest pain and should be considered, especially if there are any respiratory symptoms.
  • Esophageal rupture or esophagitis: These conditions can cause severe chest pain and are important to consider, although they are less common.
