First, an electrophysiological study will be carried out whose objective is to map the points that produce irregular electrical impulses. In this step, a catheter will be inserted into your body through a puncture, which can be made in the femoral artery. In some cases, access may be through the arm, chest or neck. The doctor will guide this catheter to the left atrium to identify the points.
After mapping, ablation is performed. The catheter will be replaced by another with a small device that will emit pulses or intense cold to isolate or cauterize tissues and vessels responsible for the arrhythmia. Pulmonary veins are usually isolated.
The patient may be kept under observation for 24 hours. Before medical discharge, the patient will receive a series of instructions detailing the care to be taken in the post-intervention period, which is usually seven days. After this period, you can continue with your daily routine.
