Defibrillators are the tiny electronic devices whose role is to lead and monitor electrical impulses of the heart and to keep normal heartbeats under control. They are implanted in the chest under the skin.
This device is required in certain people whose heart action is abnormal. Namely, normally heart rate varies from 60 to 80 beats per minute. In some patients due to heart conditions heart rate can exceed this number or be way below it. This surgery is performed in these people to re-establish normal heart rate and prevent possible complications related to abnormal heart rate. The surgery is performed by well-experienced cardiac surgeons. Patients who have suffered form arrhythmia do not have to worry about the abnormal heart rhythm any more and to take medications. The defibrillator will control and maintain normal heart rhythm for them.
Defibrillator Implant Surgery- the Very Procedure
The defibrillator is implanted in the chest under the skin. It can be also implanted above the waist line. The defibrillator contains a generator and wires. Inside the defibrillator there is a battery which needs to be replaced after certain period of time which varies from patient to patient. The ends of the leads are connected to the heart and the defibrillator. The whole procedure lasts no longer than 2 hours. Still in complicate cases it can last up to 5 hours. After the surgery the functioning of the device is checked.
The patients are hospitalized for a couple of days. After defibrillator implant surgery patients need to restrain from strenuous activities and lifting of heavy objects for certain period of time. The entire recovery time lasts approximately a few weeks.
The surgery carries certain risks. They include infections and malfunctioning of the very device. Fortunately, there are no severe complications related to defibrillator implant surgery.
After the Surgery
After the surgery has been performed the defibrillator monitors the heart rhythm and in case of any irregularity the pulse generator sends specific electrical signals to the heart. These signals restore the normal heart rate. If it happens that a heart does not respond to these initial signals the pulse generator gives a shock to the heart and this finally results in proper heart rate.
The patients need to go for regular check-ups every few months. The device and condition of its battery is checked as well. This device can function without need for the battery to be changed for 4 to 8 years. This depends on how many times the defibrillator will be activated.
