Myxedema Heart on Echocardiogram 52F with weeks of shortness of breath, pedal edema and constipation. Exam with JVD, anasarca. ECG: SR, low QRS volts. K/L ratio: normal TSH: 40, FT4 <0.1 Remember to think of myxedema heart in patients presenting with heart failure and echo which looks like amyloid heart disease.
