Web1 jun. 2024 · If transmural conduction block occurred, the epicardium was not activated and T-wave inversion was absent. In the present case, rate-dependent block of I Na produces transmural conduction delay leading to a wide QRS, while further rate-dependent block of I Na (owing to a shorter, premature R-R interval) produces transmural conduction block … Web3 sep. 2014 · Hyperkalemia. ECG characteristics of hyperkalemia, high blood potassium: P-waves are widened and of low amplitude due to slowing of conduction.
