Differential Diagnosis for Ventricular Rate 207
- Single most likely diagnosis
- Supraventricular Tachycardia (SVT): This is the most likely diagnosis due to the rapid ventricular rate, which is a hallmark of SVT. SVT is a common condition characterized by an abnormal rapid heart rhythm originating above the ventricles.
- Other Likely diagnoses
- Atrial Flutter: Atrial flutter is another possible cause of a rapid ventricular rate, especially if there is a 2:1 or 3:1 block. The ventricular rate can be regular and rapid, similar to SVT.
- Atrial Fibrillation: Although atrial fibrillation typically presents with an irregularly irregular rhythm, a rapid ventricular response can occur, especially in younger patients or those with a high sympathetic tone.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Ventricular Tachycardia (VT): Although less common than SVT, VT is a life-threatening condition that requires immediate attention. It can present with a rapid ventricular rate and may be difficult to distinguish from SVT without further evaluation.
- Wolff-Parkinson-White (WPW) Syndrome: WPW syndrome is a pre-excitation syndrome that can cause a rapid ventricular rate due to an accessory electrical pathway in the heart. It can be life-threatening if not recognized and treated promptly.
- Rare diagnoses
- Junctional Tachycardia: Junctional tachycardia is a rare condition characterized by a rapid heart rhythm originating from the atrioventricular junction. It can present with a rapid ventricular rate, but it is less common than other diagnoses.
- Mahaim Fiber Tachycardia: Mahaim fiber tachycardia is a rare condition caused by an accessory electrical pathway in the heart. It can present with a rapid ventricular rate, but it is relatively rare and often requires specialized evaluation to diagnose.
