Symptoms

Brief episodes of ventricular tachycardia may not cause any symptoms in some people. Or you may have:

• Dizziness
• Shortness of breath
• Lightheadedness
• Feeling as if your heart is racing (palpitations)
• Chest pain (angina)

Sustained and more-serious episodes of ventricular tachycardia may cause:

• Loss of consciousness or fainting
• Cardiac arrest (sudden death)

When to see a doctor

Many different conditions can cause ventricular tachycardia. It's important to get a prompt, accurate diagnosis and appropriate care. See your doctor if you or your child has any problems with the heartbeat. In some cases, urgent care is needed.

Get emergency care, or call 911 or your local emergency number for anyone experiencing these symptoms:

• Chest pain that lasts more than a few minutes
• Difficulty breathing
• Fainting
