Differential Diagnosis for Vt Storm
- Single most likely diagnosis
- Torsades de Pointes: This is a life-threatening heart rhythm disorder that can cause a "storm" of ventricular tachycardia (Vt) episodes. It is often associated with a prolonged QT interval and can be triggered by various factors, including medications, electrolyte imbalances, and congenital conditions.
- Other Likely diagnoses
- Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT): This is a rare genetic disorder that can cause episodes of ventricular tachycardia, often triggered by physical activity or emotional stress.
- Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC): This is a heart muscle disorder that can cause ventricular tachycardia and other arrhythmias, often in young people and athletes.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Myocardial Infarction (MI): Although less likely to cause a Vt storm, an MI can lead to ventricular tachycardia and should not be missed due to its high mortality rate if left untreated.
- Cardiac Sarcoidosis: This is a rare condition where granulomas form in the heart, leading to arrhythmias, including ventricular tachycardia.
- Rare diagnoses
- Brugada Syndrome: This is a rare genetic disorder that can cause ventricular tachycardia and sudden cardiac death, often in people with a family history of the condition.
- Idiopathic Ventricular Tachycardia: This is a rare condition where ventricular tachycardia occurs without any identifiable underlying cause.
