defibrillator

defibrillator,

device that delivers an electrical shock to the heart in order to stop certain forms of rapid heart rhythm disturbances (arrhythmiasarrhythmia
, disturbance in the rate or rhythm of the heartbeat. Various arrhythmias can be symptoms of serious heart disorders; however, they are usually of no medical significance except in the presence of additional symptoms.

In a typical hospital defibrillator, voltage stored by the defibrillator pushes electrical current through the chest to deliver a muscle-contracting jolt to the heart; the current is transmitted by means of electrodes or paddles placed on the chest. Automated external defibrillators are now available for use by persons with minimal medical training in emergencies when medical professionals are unavailable, and miniaturization has led to the development of the implanted internal defibrillator (also called an internal cardioverter). In the latter a microcomputer uses an electrode to monitor the heartbeat. Upon detecting a minor arrhythmia, it activates a built-in conventional pacemakerpacemaker, artificial,

Defibrillator

an apparatus designed to eliminate the major impairment of cardiac activity manifested in separate contractions at different times of individual muscle fibers of the cardiac muscle (fibrillation).

In this condition the heart cannot work efficiently. Cardiac activity is not restored spontaneously during fibrillation. The most effective means to stop fibrillation is to feed a single shortterm (0.01 second) electrical impulse created by discharge of the condenser in the defibrillator to the heart muscle (open or through the thorax). Various models of defibrillators (the ID-VEI-1 and ID-66T) have been built in the USSR. The impulses generated by these defibrillators have a less damaging effect on the heart than the apparatus of other systems. A voltage of 1.5-2.5 kilowatts is used for defibrillation on an open heart (during operations), and a voltage of 4-7 kilowatts is used with an unopened thorax.

defibrillator

[dē′fib·rə‚lād·ər] (medicine) An electronic instrument used for stopping fibrillation during a heart attack by applying controlled electric pulses to the heart muscles.

defibrillator

[de-fib´rĭ-la″ter] an apparatus used to produce defibrillation by application of brief electroshock to the heart, directly or through electrodes placed on the chest wall.automatic external defibrillator (AED) a portable defibrillator designed to be automated such that it can be used by persons without substantial medical training who are responding to a cardiac emergency.automatic implantable cardioverter-defibrillator (AICD) (implantable cardioverter-defibrillator (ICD)) an implantable device that detects tachycardia" >sustained ventricular tachycardia or fibrillation and terminates it by a shock or shocks delivered directly to the myocardium, thus preventing sudden cardiac death. Three different types of electrodes may be used: a superior vena cava spring lead, a transvenous bipolar electrode, and a ventricular patch lead. One third of the patients who have had this device implanted have received spontaneous device countershocks. Other reported side effects are similar to those of pacemakers.

Patient discussion about defibrillator

Q. Does anyone know if its possible to get breast implants if i have an implanted defibrillator? I have hypertrophic cardiomyopathy. I'm 27 and in great health, I workout 6 days a week and I have no further symptoms.A. Thanks for your help. In fact I have an appointment with my cardiologist in a couple of weeks and if he says its OOK I will definitely consult it with the plastic surgeon as well. However I always try to do some additional research on my own and get second opinions.
Ince again,
Thanks!
