Indications for Use: When combined with a stimulation lead system, the Model 3077 SSI temporary pulsegenerator can be used whenever temporary atrial or ventricular stimulation is indicated. The device can beemployed for therapeutic as well as diagnostic purposes or be used prophylactically. When the fetus is ready to be born the pacemakers set off a series of rhythmic contractions in the uterine muscle that gradually force the infant out into the birth canal.wandering pacemaker a condition in which the site of origin of the impulses controlling the heart rate shifts from the head of the sinoatrial node to a lower part of the node or to another part of the atrium.3.

Leute kennenlernen bremerhaven See Artificial pacemaker, Asynchronous pacemaker, Automatic antitachycardia pacemaker, Cardiac pacemaker, Circadian pacemaker, Demand pacemaker, Dual chamber pacemaker, External pacemaker, Programmable pacemaker, Triggered pacemaker, Wandering pacemaker. In cardiology, a specialized cell or group of cells that automatically generates impulses that spread to other regions of the heart.An ectopic or idioventricular pacemaker, originating in the atria, AV node, or ventricle, may cause contractions in cases of abnormal heart functioning. 2 an electric apparatus used in most cases to increase the heart rate in severe bradycardia by electrically stimulating the heart muscle.A pacemaker may be permanent or temporary, emit the stimulus at a constant and fixed rate, or fire only on demand.
Single chamber temporary pacemakers

Pacemakers are used most often to treat patients with symptomatic slow heart rates or long pauses between heart beats (such as patients with third-degree heart block, symptomatic second-degree heart block, bifascicular block with first-degree heart block, carotid sinus hypersensitivity, and tachybrady syndrome) and slow ventricular response rates.Many are designated by a three to five letter code used to categorize them functionally.demand pacemaker an implanted cardiac pacemaker in which the generator stimulus is inhibited by a signal derived from the heart's electrical activation (depolarization), thus minimizing the risk of pacemaker-induced fibrillation.1 the sinoatrial node composed of specialized nervous tissue and located at the junction of the superior vena cava and the right atrium.
It initiates the contractions of the atria, which transmit the impulse onto the atrioventricular (AV) node, thereby initiating the contraction of the ventricles.Called also DDD pacemaker.; it converts radiofrequency signals into electrical impulses that stimulate the phrenic nerve, resulting in descent and flattening of the diaphragm and improved inhalation of air.Called also diaphragmatic pacemaker.synchronous pacemaker an implanted pacemaker that synchronizes the physiological events in the atrium with those of the ventricle; it stimulates the ventricle when triggered by the P wave from the atrium.transcutaneous pacemaker a temporary pacemaker in which large surface, high impedance electrodes are applied to the anterior and posterior chest walls to deliver high current stimuli of long duration for pacing of the ventricles.transvenous pacemaker an artificial pacemaker, either external or implanted, that is connected to the heart by pacing leads passed through the venous circulation to make contact with the endocardium of the right atrium or right ventricle.uterine pacemaker either of the two regulating centers that control uterine contractions, located near the openings of the fallopian tubes.The normal rhythm, 60 to 100 contractions per minute, increases during physical or emotional stress and decreases during rest.The pace varies from person to person and is affected by abnormal conditions such as heart injuries and generalized infections.
