Ventricular tachycardia

• Sensation of feeling the heart beat (palpitations)
• Light-headedness or dizziness
• Fainting
• Shortness of breath
• Chest discomfort (angina)

Note: Symptoms may start and stop suddenly. In some cases, there are no symptoms.

Ventricular tachycardia can occur in episodes during which the person will have a rapid pulse or the symptoms described above. The blood pressure may be normal or low. Loss of consciousness may occur. Ventricular tachycardia is a potentially lethal arrhythmia and may result in an absent pulse.

Ventricular tachycardia may be seen on:

• An ECG
• A continuous ambulatory electrocardiogram (Holter monitor)
• A loop recorder, for ambulatory ECG recordings exceeding 24 hrs
• An intracardiac electrophysiology study (EPS)

Blood chemistries and other tests may be performed.
