I had an EKG which showed a LBBB. This led to a visit with a Cardiologist who ordered a stress test (passed, no blockages) and an echocardiogram. The echocardiogram showed some weakening of the heart muscle, "it's not pumping as strong as we'd like". The Cardiologist said I don't really have anything to worry about. He suggested some lifestyle changes (more exercise and losing some weight) and changed one of my blood pressure meds. I've had high blood pressure for about 10 years, usually under control with Hyzaar and Norvasc. I feel fine. Should I get a second opinion?
