Many airlines pay for AMAS. Might be cheaper than an appointment with your AME. You can also contact your Regional FAA Flight Surgeon and see what has to be done.
Here's a good article on Heart Issues:

Less than 1% of heart issues lead to permanent grounding:
In 1997, the FAA granted nearly 6,500 Special Issuance Authorizations/SIA (waivers) for pilots with coronary artery disease. Of these, most were for coronary artery disease or heart attacks (myocardial infarctions) treated with bypass grafting, angioplasty and/or intracoronary artery stents. With respect to class of medical certificate, 509 were for First Class, 512 were for Second Class and 5,555 were for Third Class. Pilots with heart valve replacements, rhythm disturbances, pacemakers and heart failure also were granted SIAs. Only 0.1% of medical applications to the FAA receive a final denial.
