Shingles affects the nerves. Shingles is caused by the varicella-zoster virus â the same virus that causes chickenpox. Anyone who's had chickenpox may develop shingles. After you recover from chickenpox, the virus can enter your nervous system and lie dormant for years.
Heart ablation, or cardiac ablation, is a surgical procedure that is used to correct abnormal heart rhythms. Catheter tubes are used to correct structural heart problems that prevent normal heart rhythms. Malfunctioning heart tissue is scarred or destroyed.
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 heartâs chambers. This scar tissue is a good thing. It will help your heartbeat stay in rhythm.
