such as radiofrequency ablation (RFA) or cryoballoon ablation. The initiation of AF requires both a trigger either within or near the atria and a susceptible substrate within the atria.

During the procedure, catheters are inserted into the heart to deliver radiofrequency energy or cryoballoon ablation to destroy tissue on the veins that is causing disruptive electrical signals.

PETALING JAYA: KPJ Kluang Specialist Hospital last month became the first hospital in Johor to carry out a cryoballoon ablation procedure combined with Intracardiac Echocardiography (ICE).
