A possible complication of dual-chamber artificial pacemakers is 'pacemaker-mediated tachycardia' (PMT), a form of reentrant tachycardia. In PMT, the artificial pacemaker forms the anterograde (atrium to ventricle) limb of the circuit and the atrioventricular (AV) node forms the retrograde limb (ventricle to atrium) of the circuit.

An artificial cardiac pacemaker (or artificial pacemaker, so as not to be confused with the natural cardiac pacemaker) or just pacemaker is an implanted medical device that generates electrical impulses delivered by electrodes to the chambers of the heart either the upper atria, or lower ventricles to cause the targeted chambers to contract and ...
For example, in most humans, this is a single artery, although in some cases there have been either 2 or 3 sinoatrial node arteries supplying the SA node. Also, the SA node artery mainly originates as a branch of the right coronary artery ; however in some individuals it has arisen from the circumflex artery , which is a branch of the left ...
Pacemakers are also sometimes used temporarily when someone is recovering from a heart attack or heart surgery, but in this case only the wires are inserted into the body; the pacemaker box stays ...
An artificial organ is a human-made organ device or tissue that is implanted or integrated into a human – interfacing with living tissue – to replace a natural organ, to duplicate or augment a specific function or functions so the patient may return to a normal life as soon as possible. [1]
Diaphragm pacing (and even earlier as electrophrenic respiration [1] [2]) is the rhythmic application of electrical impulses to the diaphragm to provide artificial ventilatory support for respiratory failure or sleep apnea.
In the pictures, a smiling Strahan is seen walking and posing on the sandy beach in a black floral bikini and hoop earrings. "And we're back," the daughter of former couple Michael Strahan and ...
Accelerans nerve forms a part of the sympathetic branch of the autonomic nervous system, and its function is to release noradrenaline at its endings on the heart. The heart beats according to a rhythm set up by the sinus-atrial node or pacemaker, which is located on the right atrium of the heart.
