Hey!
I came across a patient with VVIR pacing today. I was wondering why we didn't do DDD instead. Let's learn what it is and why (In short!)
VVI - Ventricular demand pacing - ventricle paced, ventricle sensed, and pacemaker inhibited in response to a sensed beat.
Advantages: Ability to protect the patient from dangerous bradycardias.
Disadvantages: Cannot maintain AV synchrony (lack of AV synchrony can result in pacemaker syndrome.)
Indications: Chronic atrial fibrillation with a slow ventricular response.
My patient has chronic atrial fibrillation, that's why :)
