Flashcards in Bradyarrythmias Deck (12):
Cells in the AV node have a relatively higher membrane potential.
Cells in the AV node exhibit spontaneous depolarization during phase 4 of the action potential.
Cells in the AV node have slower phase 0 depolarization.
Permanent pacing is the only reliable therapy for symptoms arising from AV conduction block.
Components of AV conduction axis.
The time from the most rapid deflection of the atrial electrogram in the His bundle recording to the His electrogram
conduction through the AV node
Normal AH interval
The time from His electrogram to the earliest onset of QRS
Normal HV interval
Prolonged AH interval
type 1 second degree AV block
