Risk factors

Any condition that puts a strain on the heart or damages heart tissue can increase your risk of ventricular tachycardia. Lifestyle changes or medical treatment may decrease the risk associated with the following factors:

• Heart disease
• Medication side effects
• Severe electrolyte imbalances
• Use of stimulant drugs such as cocaine or methamphetamine

If you have a family history of ventricular tachycardia or other heart rhythm disorders, you may have an increased risk of ventricular tachycardia.
