What I could understand is steroids
for multiple sclerosis?, EKG showing brady cardia that is slow heart rate
if this is sinus bradycardia? heart rate 40-45 beats per minute is OK, Left atrial size is more ecg wise suggested, for this only a 2 D Echocardigraphy is advised. It will rule out any valve defect or leakage /stenosis . Is heart chamber
is really enlarged and what is the level of heart function that is Ejection Fraction
. You shoud not worry as your appointment is late.Hpoe you get a normal echocardiography
. In the mean time take your steroids as advised by doctor. Best of luck.
