The surgery is where they drill a hole through the wall of your heart to burn the nerves that are firing wrong. Rehab time is only really a week, two days for the surgery and then a couple to really get back into it.. For me it was 6 months.. The Dr ablated the nerve that controls the right hemi diaphragm and collapsed my right lung. Still have that tied up in court. So 99% of the time it is an easy procedure (So they say) but there can be issues.
