Differential Diagnosis for 160 bpm in a 56 yo Female
- Single most likely diagnosis
- Supraventricular Tachycardia (SVT): This is a common cause of a rapid heart rate, especially in women. The patient's age and presentation are consistent with this diagnosis.
- Other Likely diagnoses
- Sinus Tachycardia: This could be due to various causes such as anxiety, dehydration, or infection. The patient's history and physical examination would help differentiate this from other causes.
- Atrial Fibrillation: Although less common in younger women, atrial fibrillation can occur at any age and may present with a rapid and irregular heart rate.
- Ventricular Tachycardia: Although less common, ventricular tachycardia can occur in women, especially those with underlying heart disease.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Cardiac Tamponade: Although rare, cardiac tamponade can present with tachycardia and is a life-threatening condition that requires immediate attention.
- Pulmonary Embolism: A large pulmonary embolism can cause tachycardia and is a potentially life-threatening condition that requires prompt diagnosis and treatment.
- Thyrotoxic Crisis: This is a rare but life-threatening condition that can cause tachycardia, among other symptoms.
- Rare diagnoses
- Wolff-Parkinson-White Syndrome: A rare condition that can cause SVT due to an accessory electrical pathway in the heart.
- Pheochromocytoma: A rare tumor that can cause episodic tachycardia and hypertension.
- Hyperthyroidism: Although not typically presenting with such a high heart rate, hyperthyroidism can cause tachycardia and is worth considering in the differential diagnosis.
