| | Artificial pacemaker - Wikipedia, the free encyclopedia |
 | | External pacemakers can be used for initial stabilization of a patient, but implantation of a permanent internal pacemaker is usually required for most conditions. | | | External cardiac pacing is typically performed by placing two pacing pads on the chest wall. | | | A substantial external device, it was somewhat crude and painful to the patient in use. |

| | Cardiac Services - Pacemaker & Defibrillators |
| | Whether a patient needs a pacemaker or an implantable cardioverter-defibrillator, is a complicated decision dependent on a patient's history, an electrophysiology study, and other cardiac therapy. | | | This is a life-saving therapy and is similar to the machines ambulances bring to patients in the midst of cardiac arrest (no heart blood output). | | | An implantable cardioverter-defibrillator is a device that resuscitates the heart - attempts to restore a normal heart beat in a patient whose heart is beating rapidly and in a disorganized way. |

| | #1) "external cardiac pacing appears to be the method of choice for the immediate treatment of patients with unexpected circulatory arrest from cardiac standstill." #2) Chest pain and muscle twitch intensity varied from patient to patient. | | | The cardiac arrest was terminated in each case by the electric pacemaker so that thoracotomy and cardiac massage were not necessary. | | | He later incorporated the principle of the mechanical stimulus, such as a chest thump or repetitive chest thumps, to cause an asystolic heart in cardiac standstill arrest to beat into an external mechanical cardiac stimulator which could deliver a mechanical precordial chest thump timed to the nonvulnerable phase of the cardiac cycle. |

| | transthoracic pacemaker, an external cardiac pacemaker delivering stimuli through the chest wall, such as one connected to the heart by percutaneous pacing wires introduced through a transthoracic needle or one in which large electrodes are placed on the skin over the heart. | | | transthoracic pacing, a method for temporary cardiac pacing in which a hooked pacing lead is attached to the ventricular endocardium by insertion through the chest wall or epigastric area and then the ventricular wall; it is used in emergency situations, usually cardiac arrest, as an alternative to transcutaneous pacing. | | | transvenous pacemaker, an artificial cardiac pacemaker, either external or implantable, that is connected to the heart by pacing leads passed through the venous circulation. |

| | Purdue Engineers Develop Two-Speed Cardiac Pacemaker |
| | Depending upon the particular problem, the pacemaker might be used continuously to stimulate the heart, or serve as a back-up to the natural pacemaker, triggered when there is a long pause or abnormal heart beat. | | | Though the new pacemaker has not yet been tested in humans, laboratory research with animals has been very successful, says Fearnot. | | | Since muscles are only 15 to 20 percent efficient, 80 percent of the energy is given off in heat, which is then carried away by the blood to the heart," he explains. |
