diastolic dysfunction or stiff heart

I come and go on here sometimes, but have just been diagnosed with diastolic dysfunction with ejection fraction of 50-55% all four valves have a trace of regurge. Back in march my myoglobin was 1089 with all other cardiac markers elevated except troponin at 0.4. Just a guestion is this cardiomyopathy? Pulmonologist was a little erked that the cardiologist told me that my echo was fine. Pulmonologist said its not fine you have stiff heart. I believe scarring. I get short of breath and have scarring in my lungs. I believe Im being worked up for sarcodosis. I also had a holter done because my heart races to the 160's. The doctor also said that the holter was fine just a little tachycardia. Uh excuse me? I got a copy of my medical records and found out prior to seeing my pulmonary doc. The cardiologist put me on digoxin because of the bad reaction I had to betablockers that sent me to the er in march. I dont get it maybe the cardio doc just didnt look at my echo or my holter monitor. The holter showed 136,898 beats of supraventricular tachycardia.
