Effects of thyroid hormone on action potential and repolarizing currents in rat ventricular...

Studies the effects of triiodothyronine (T3) on the electrophysiological properties of ventricular myocytes isolated from euthyroid and hypothyroid rats using whole cell patch clamp techniques. Prolonged action potential duration shown by hypothyroid ventricular myocytes; Unaffected transient outward current with the acute application of T3.
