The primary function of a dual-chamber pacemaker is to mimic the normal physiologic sequence of heartbeats by monitoring the atrial and ventricular heartbeats and coordinating them for pacing.
There are four types of dual-chamber pacemakers: DDD, DVI, VDD, and DDI. The most common type of pacemaker is the DDD, whose main functions are atrial and ventricular dual-chamber sequential pacing, dual atrial and ventricular sensing, and dual trigger inhibition. It is mainly used in patients with pathological sinus node syndrome, sinus arrest and high degree of AV block.
If implantation of a dual-chamber pacemaker is really needed due to illness, it should be treated in a regular hospital and should not be handled without authorization in order to avoid delaying the condition. Pay attention to rest on weekdays, avoid strenuous exercise, quit smoking and drinking, and rationalize your diet.
