What Is Dddr Pacing

The latest cardiac pacing mode to become available is the dual-chamber, rate-modulated mode (referred to as DDDR), which restores both rate responsiveness and atrioventricular synchrony in patients with sinus node dysfunction and atrioventricular block

What is Dddr on pace maker?

DDD = dual-chamber antibradycardia pacing; if atria fails to fire, it is paced. If the ventricle fails to fire after an atrial event (sensed or paced) the ventricle will be paced. DDI = Like above, but the atrial activity is tracked into the ventricle only when the atria is paced.

What does an asynchronous pacing mode indicates?

Cardiac pacing set at a rate independent of the heart’s own pacemakers. This allows pacemaking at heart rates that are faster or slower than the patient’s diseased pacemaker.
