What Are Pacemakers & Defibrillators?

Answers from Our Los Angeles Cardiovascular Surgeon

Cardiac pacemakers and implantable cardioverter defibrillators are implanted in the chest to provide necessary emergency assistance. These device treat arrhythmias, which are disorders in the heart rate or rhythm, such as heartbeats that are too quick, too slow, or too irregular.

Pacemakers serve the purpose of keeping the heart beating at a proper rate and only activate when necessary. Defibrillators are bigger devices that have a pacemaker built in, and are used to prevent death from a cardiac arrest. Both of these devices are extremely reliable, and can be uniquely programmed to your specific requirements and medical condition.

Benefits of Having a Pacemaker or Defibrillator Implanted:

  • Minor surgery with lowers risks
  • Minimal recovery time
  • Can help patients when medication is not enough
  • An effective way to control fast, slow, or irregular heart rhythms
  • A device that is able to save lives in emergency situations

Effective Surgeries with Short Recovery Times

Because of the numerous benefits that you can receive from implantation, as well as the minimal risks, this procedure is often a terrific solution for controlling your heart rhythms. The surgery itself typically only lasts a few hours, and can be performed while you are awake through the numbing of the implantation area and a sedative. Recovery usually only requires a day or two stay in the hospital, as patients are monitored to ensure that the device is properly functioning. Life-threatening complications are extremely rare, and you should be able to return to normal daily activities within a matter of days.
