Ventricular tachycardia (VT): The ventricles are the two lower chambers of your heart.If SVT occurs frequently or for long periods, the arrhythmia can lead to heart damage and severe symptoms. But you’ll experience episodes of racing heartbeats (up to 300 beats per minute). Supraventricular tachycardia (SVT): If you have SVT, your heart still pumps blood normally.Atrial flutter results in a heartbeat that’s faster than normal and like Afib, increases your risk for blood clots and stroke. Atrial flutter: With this condition, the atria contract to pump blood, but they do it too quickly.When your blood doesn’t move through your heart properly, it increases your risk of forming blood clots within your heart and the risk of stroke if the clot travels to your brain. Without strong contractions, your heart can’t pump blood. When you have Afib, the upper chambers of your heart (called the atria) beat irregularly. Atrial fibrillation (Afib): Afib is the most common reason for heart ablation.Heart ablation procedures can treat all types of irregular or abnormal heart rhythms, including: What conditions does cardiac ablation treat?Ĭardiac ablation treats heart arrhythmias that can’t be controlled with medication. Scarring in these areas helps to block your heart from producing irregular or abnormal rhythms. Ablation describes any technique used to target and eliminate abnormal electrical signals from your heart.ĭuring cardiac ablation, a cardiologist (a doctor who specializes in heart conditions) uses hot or cold energy to create tiny scars in heart tissue, targeting the areas of your heart causing the arrhythmia. Heart ablation (also called cardiac ablation) describes a variety of procedures that treat irregular or abnormal heart rhythms ( arrhythmias).
