There is a company, HeartCare Corp, that makes a machine that looks like an EKG, but can detect a wide variety of heart damage, including myocarditis. They can assess their team in a day.
Just get a 12 lead EKG, a troponin and D Dimer lab test. That will give you a good picture of how damaged your heart is from taking the jab.
