Ventricular Arrhythmias


What is ventricular arrhythmia?
Ventricular arrhythmias include ventricular tachycardia and ventricular fibrillation. Both are life threatening arrhythmias most commonly associated with heart attacks.

Causes and Risk Factors

What causes ventricular arrhythmias?
Ventricular arrhythmias result when electrical impulses generated in your heart's ventricles disturb the normal pattern generated by the sinoatrial (S-A) node and the heart's electrical conduction system.


What are symptoms of ventricular arrhythmia?
Someone with a ventricular arrhythmia may experience fainting spells, blackouts, temporary blind spots, chest pounding, or dizziness.


How is ventricular arrhythmia diagnosed?
To diagnose an arrhythmia, your doctor will typically start with an electrocardiogram (ECG) test.
