Management of arrhythmias and oversensing

Question 1

Associer à un tracé: 
Which answer(s) is(are) true regarding the automatic mode switching algorithm?
Your answerChoice

A. AMS occurs when the filtered atrial rate interval (FARI) < the atrial tachycardia detection interval 

B. if actual PP ≤ FARI: FARI decremented by 38 ms

C. if actual PP> FARI: FARI incremented by 25 ms

D. return to synchronous mode when FARI > the maximum synchronous rate interval

E. return to synchronous mode when FARI >  the atrial tachycardia detection interval
