this is a particular setting on a pacemaker which essentially senses if the ventricle depolarises, if it does not the PM will activate it and ensure the heart carries on beating.
Also:
A demand pacemaker (there are several types) kicks in after your cardiac function varies outside a pre-set normal rate. It then brings your heartbeat into a more efficient rhythm. (Sinus-rhythm.)
A demand pacemaker does not take the place of an implanted defibrillator! If a genuinely life-threatening cardiac arrhythmia develops, it takes a defibrillator -- an implanted one or an external unit used by someone trained to respond -- to correct ventricular fibrillation. If it is not corrected, v-fib is fatal.

What kind of pacemaker has leads going to the right atrium and the left ventricle?
Dual.
Heart block may be treated by implanting into the heart a device called?
A pacemaker is a device implanted into the chest that has a wire lead that sits in the right ventricle (single chamber pacer), the right atrium and ventricle (A-V pacer), or the right ventricle and the coronary sinus (dual chamber pacer) and provides electrical stimulation to the cardiac muscle.
What is the difference between dual chamber pacemaker and bi-ventricular pacemaker?
A dual chamber pacemaker stimulates both the atrium and ventricle of the heart, coordinating their contractions to improve heart rhythm and function in patients with atrioventricular (AV) block or similar conditions. In contrast, a bi-ventricular pacemaker (also known as a cardiac resynchronization therapy device) stimulates both ventricles to improve the heart's pumping efficiency, particularly in patients with heart failure and electrical conduction abnormalities. Essentially, the dual chamber pacemaker focuses on atrial and ventricular coordination, while the bi-ventricular pacemaker aims to synchronize the contraction of both ventricles.

When the heart relaxes what does it do?
It just keeps beating but, after relaxing it beats at a slower rate.
What is dd pacemaker?
Pacemakers all get an initial code that describe the device's functional abilities. The code consists of at least three letters, sometimes four or even five. There is no such thing as a DD pacemaker, but there is a DDD and a DDI pacemaker (also a DDDR, and DDIR). Since DDD is the most commonly implanted pacemaker in the U.S., it is likely that DDD was meant. The first letter indicates where the pacemaker paces. It can pace in the upper chamber (atrium, in which the case the letter is A), the lower chamber (ventricle, in which case the letter is V), or both (in which case the letter is D for "dual"). The second letter indicates where the pacemaker senses. Sensing means "listen." Pacemakers are able to monitor the heart and detect or listen to the heart rhythm. Again, the letter codes here are A, V, D. The third letter is a bit trickier in that it indicates what the pacemaker does if the heart beats on time. If the letter is I it means "inhibit." That means if your heart beats on its own, it inhibits the pacemaker or forces it to stay on standby. If the letter is T it means trigger, that is, if the heart beats on its own, the pacemaker will be triggered to pace. This is appropriate when the upper chamber beats and the pacemaker gets ready to cause the lower chamber to beat in appropriate response. The third option is D for dual, meaning the pacemaker will inhibit (for the ventricle) but trigger for the atrium. If the fourth letter is an R, the pacemaker has a special sensor that allows it to increase its rate when you are physically active. These codes are widely used by clinicians and are understood around the world. Pacemakers are coded on the box to the highest performance they can achieve. For instance, a DDD pacemaker can pace or sense both chambers of the heart but a doctor can program it in such a way that it paces and senses only one chamber of the heart. Nevertheless, on the pacemaker labeling, it will state the highest level of function of which the device is capable.

How are the wires of a pacemaker attached to the heart?
The wires of a pacemaker, known as leads, are attached to the heart by inserting them through a vein and guiding them to the heart chambers, typically the right atrium and ventricle. Once positioned, the leads are secured using small screws or tines that anchor them to the heart tissue. This allows the pacemaker to deliver electrical impulses effectively, helping to regulate the heart's rhythm. The procedure is usually done under local anesthesia and can be performed using minimally invasive techniques.
How do they connect a pacemaker to the heart?
A pacemaker is connected to the heart through one or more leads, which are thin, insulated wires. These leads are inserted through a vein and threaded into the heart, typically into the right atrium and/or ventricle. Once in place, the leads are attached to the pacemaker device, which is usually implanted under the skin, often in the chest area, to deliver electrical impulses that help regulate the heart's rhythm. The procedure is performed under local anesthesia and can be done using minimally invasive techniques.
