Hypothyroidism is associated with a decreased metabolic rate, which slows down heart rate and cardiac output. Sinus bradycardia may result from this decreased metabolic rate. Atrial fibrillation and supraventricular tachycardia are more commonly associated with hyperthyroidism. U waves are not commonly seen in hypothyroidism.
