Webb24 mars 2024 · A conduction disorder, also known as heart block, is a problem with the electrical system that controls your heart’s rate and rhythm. This system is called the cardiac conduction system. Normally, the electrical signal that makes your heart beat travels from the top of your heart to the bottom. The signal causes your heart muscle to … Webb2 apr. 2024 · Narrow QRS indicates simultaneous activation of both ventricles Atrial tachycardias generally have a narrow QRS because their ventricular activation occurs via the AV node and the ventricular conduction system (His-Purkinje system), which leads to simultaneous activation of both ventricles.

Bidirectional ventricular tachycardia VHRM

WebbThese events are sequential, precisely timed, and interdependent, requiring the rapid synchronous electrical stimulation provided by the His-Purkinje system. RV pacing generates slow asynchronous electrical stimulation, which disrupts the timing of the cardiac cycle and causes LV mechanical asynchrony [ 25 ] .
