As a medical professional with expertise in cardiology, I can provide you with an informed explanation of the causes of polymorphic ventricular tachycardia (PVT). Polymorphic ventricular tachycardia is a type of abnormal heart rhythm characterized by rapid and chaotic heartbeats that originate in the ventricles, the lower chambers of the heart.

**Causes of Polymorphic Ventricular Tachycardia:**


1. Underlying Heart Conditions: PVT can be a complication of various heart diseases, including coronary artery disease, cardiomyopathy, and congenital heart defects.


2. Electrolyte Imbalances: Imbalances in the body's electrolytes, particularly potassium, magnesium, and calcium, can lead to PVT.


3. Drug-Induced: Certain medications, such as certain antiarrhythmic drugs, can trigger PVT, especially when they are used inappropriately or in combination with other drugs.


4. Long QT Syndrome: This is a genetic disorder that affects the heart's electrical activity and can lead to PVT.


5. Commotio Cordis: A rare cause, this is a sudden impact to the chest that can disrupt the heart's rhythm and cause PVT.


6. Brugada Syndrome: Another genetic condition that affects the heart's electrical system and can result in PVT.

7. **Acute Myocardial Infarction (Heart Attack):** Damage to the heart muscle from a heart attack can lead to PVT.

8.
Other Factors: Stress, excessive alcohol consumption, and certain medical conditions like hypothyroidism can also contribute to the development of PVT.

It's important to note that PVT is a serious medical condition that requires immediate attention. If you or someone you know is experiencing symptoms suggestive of PVT, seek emergency medical care.

The commonest cause of PVT is myocardial ischaemia. Torsades de pointes (TdP) is a specific form of polymorphic ventricular tachycardia occurring in the context of QT prolongation; it has a characteristic morphology in which the QRS complexes ��twist�� around the isoelectric line.
