Differential Diagnosis for Palpitations in a 35-year-old Female
Single Most Likely Diagnosis
- Anxiety or Stress-related Palpitations: This is often the most common cause of palpitations in a young, otherwise healthy female. The symptoms can be triggered by stress, anxiety, or panic attacks, and are usually benign.
Other Likely Diagnoses
- Premature Atrial Contractions (PACs) or Premature Ventricular Contractions (PVCs): These are common benign arrhythmias that can cause palpitations. They are often seen in healthy individuals and can be triggered by caffeine, nicotine, or stress.
- Mitral Valve Prolapse: A condition where the mitral valve does not close properly, causing palpitations. It is a common condition in young women and is often benign.
- Hypothyroidism: An underactive thyroid gland can cause palpitations, among other symptoms. It is a common condition in women and can be easily diagnosed with blood tests.
Do Not Miss Diagnoses
- Cardiac Arrhythmias (e.g. Atrial Fibrillation, Supraventricular Tachycardia): Although less common, these conditions can be life-threatening if not diagnosed and treated promptly. They require immediate medical attention.
- Cardiomyopathy: A disease of the heart muscle that can cause palpitations, among other symptoms. It is a serious condition that requires prompt diagnosis and treatment.
- Pulmonary Embolism: A blood clot in the lungs that can cause palpitations, among other symptoms. It is a life-threatening condition that requires immediate medical attention.
- Hyperthyroidism: An overactive thyroid gland can cause palpitations, among other symptoms. If left untreated, it can lead to serious complications.
Rare Diagnoses
- Long QT Syndrome: A rare genetic disorder that can cause palpitations and increase the risk of sudden cardiac death.
- Brugada Syndrome: A rare genetic disorder that can cause palpitations and increase the risk of sudden cardiac death.
- Arrhythmogenic Right Ventricular Cardiomyopathy: A rare condition that can cause palpitations and increase the risk of sudden cardiac death.
- Pheochromocytoma: A rare tumor of the adrenal gland that can cause palpitations, among other symptoms. It is a serious condition that requires prompt diagnosis and treatment.
