What does VVI pacemaker mean?
A pacemaker in VVI mode denotes that it paces and senses the ventricle and is inhibited by a sensed ventricular event. The DDD mode denotes that both chambers are capable of being sensed and paced.
When is a VVI pacemaker used?
VVI/VVIR pacing is indicated for patients with chronic atrial arrhythmias that are not expected to return to sinus rhythm. While VVI/VVIR protects patients from lethal bradyarrhythmias, it does not maintain AV synchrony, which sometimes leads to “Pacemaker syndrome.”
What is AAIR pacing?
AAIR mode delivers atrial pacing with rate response. The AAI/AAIR pacing mode is indicated in patients with sick sinus node disease with intact atrioventricular conduction. It is important to evaluate the quality of atrioventricular conduction.
What does VVI stand for?

| VVI | Single Chamber Ventricular Pacemaker |
| VVI | Vietnam Veterans Institute (est. 1981) |
| VVI | Velocity Vector Indicator (gaming) |
| VVI | Vehicle Verification and Identification |
What is AOO pacing?
In AOO mode, the atrium is paced at a set rate regardless of atrial activity; this is asynchronous atrial pacing. In AAI mode, the atrium is sensed and the pacemaker is inhibited if the native atrial rate rises above the pacemaker set rate; this is demand atrial pacing.
What does Vvir stand for?

| VVIR | Ventricular Rate Modulated Pacing (pacing heart failure fibrillation) |
| VVIR | Voice and Visage of the Islamic Republic (Iranian Radio and Television) |
Is there a difference between a defibrillator and a pacemaker?
What a pacemaker does is keep the heart beating at the proper rate and from beating too slow. It also will only activate if it is needed, it is not shocking people all the time. An implanted defibrillator is a bigger device. It is there to prevent death from a cardiac arrest.
What does VVI pacing mean?
VVI pacemaker means: After surgery, the patients Vehicle Licensing Agency informs that he has a built VVI pacemaker and therefore they issued him an appropriate driving license. You need to avoid the stress of exercise three to four weeks after installation of VVI pacemaker, after that the patient can continue with most physical activities,…
VVI pacemaker is the most common type of pacemaker. VVI pacemaker is a medical instrument that allows to heart muscle to work properly. In the surgical procedure, a specialist cardiologist, incorporating VVI pacemaker into the chest wall and VVI pacemaker with wires connect to heart in the right upper heart chamber or on the right ventricle.
What is VVI mode pacemaker?
A pacemaker in VVI mode denotes that it paces and senses the ventricle and is inhibited by a sensed ventricular event. The DDD mode denotes that both chambers are capable of being sensed and paced.
What does DDD and VVI mean?
DDD and VVI are pacemaker therapy modes that your doctor can program in your device. These are just two of many options. Each letter indicates something different (A=Atrium; V=Ventricle; D=Dual or both A and V; and O=none). The first letter indicates the chamber of the heart being paced.
