Implications of Left Bundle Branch Block in Takotsubo

As a result of underlying heart disease, this cardiac conductive tissue can become damaged from ischemia (a deprivation of oxygenated blood). This damage results in the inability of this neural-like tissue to conduct electrical signals and control the heart as efficiently as before, resulting in the cardiac abnormality known as a bundle branch block (BBB).

Web23 jun. 2024 · During tachycardia, the sinus impulse that is already blocked anterogradely in the LBB also fails to depolarize LBB retrogradely due to frequency (tachycardia)-dependent block. The following impulse finds the LBB in a non-refractory state and is conducted normally resulting in a 2:1 LBBB pattern on EKG. Web23 jun. 2024 · There are two proposed mechanisms of intermittent LBBB: tachycardia-dependent bidirectional block and supernormal conduction [ 10 ]. In tachycardia-dependent bidirectional block, the sinus impulse that is already blocked anterogradely in the LBB also fails to depolarize LBB retrogradely due to frequency (tachycardia)-dependent block.
