Ventricular tachycardia (VT) is an abnormal rapid heart rhythm originating from the lower pumping chambers of the heart (ventricles). The normal heart usually beats between 60 and 100 times per minute, with the atria contracting first, followed by the ventricles in a synchronized fashion.
It's rare, but sometimes you may need to have ablation of the AV node. It's the place that electrical signals pass through as they travel from the upper to the lower heart chambers. Doctors may do ablation there if you have very rapid atrial fibrillation that you can't control with medication.
BACKGROUND Ablation of long-standing persistent atrial ﬁbril-lation (AF) is highly variable, with differing techniques and out-comes. OBJECTIVE The purpose of this study was to undertake a system-atic review of the literature with regard to the impact of ablation technique on the outcomes of long-standing persistent AF abla-tion.
What Is Catheter Ablation? Catheter ablation is a nonsurgical way to treat atrial fibrillation (AFib), a type of irregular heartbeat. It destroys the tissue that may be causing the heartbeat to get off course. This creates scar tissue inside your heart’s chambers. This scar tissue is a good thing. It will help your heartbeat stay in rhythm.
