Q: Pericarditis in hypothyroidism fails to produce diffuse ST- and T-wave elevations on EKG. What is the probable cause?
Pericarditis in hypothyroidism fails to produce diffuse ST and T-wave elevations on EKG due to low voltage. Other changes which can be noted on EKG in hypothyroidism include bradycardia, prolonged QTc, and atrioventricular blocks.
