PY - 2020 T2 - Tintinalli's Emergency Medicine: A Comprehensive Study Guide, 9e AB - Thyroid hormone affects virtually all organ systems and is responsible for increasing metabolic rate, heart rate, and ventricle contractility, as well as muscle and CNS excitability. The thyroid hormones are thyroxine (T4) and triiodothyronine (T3). The ratio of T4 to T3 released in the blood is 10:1. Peripherally, T4 is converted to the active T3, which is three to four times more potent than T4.
