The defibrillator is a device slightly larger than a pacemaker, which is implanted in patients with increased risk of sudden death. The defibrillation system consisting of the device and electrodes. The device is the battery, capacitors and a computer that “read” anytime the patient’s electrocardiogram and interferes respectively when it is appropriate.
In the case of bradycardia, the defibrillator is pacing the heart as a conventional pacemaker, while in case of threatening tachycardia provides therapy aimed at reduction of the arrhythmia.
In ventricular tachycardia the defibrillator is pacing the heart at a frequency slightly higher than that of tachycardia and terminates her painlessly (Antitachycardia Pacing ).
In cases of ventricular fibrillation or ventricular tachycardia with very high frequency given defibrillation (shock), which also terminates the tachycardia but painfully.
We use Implantable defibrillator to patients with underlying heart disease and a high risk of sudden cardiac death, such as myocardial infarction, dilated cardiomyopathy, cardiomyopathy and electrical diseases of the heart.
The operation is similar to the conventional implanted pacemaker and is performed under local anesthesia in the left region of the upper half thorax rib cage and is usually administered intravenously suppressive treatment aimed mild intoxication.
The entire procedure usually takes about 1 hour. Potential complications, as with any implant is hematoma in the housing area, the electrode movement (less than 1 every 100 operations), pneumothorax (air leakage around the lungs in less than 1 of every 100 procedures), infection (1 every 500 procedures), and the collection of blood around the heart (1 every 500 procedures)
The patient leaves the hospital the next day and the sutures are removed after 7-10 days. In the first month limitation is required on the upper end moves to prevent movement of the electrodes. We monitor and control the device in the month after surgery and then every six months via a dedicated programmer.
Tips after the implantation of defibrillator
Using a mobile phone is allowed on the opposite side from that which has been implanted and patients should avoid placing the mobile phone over the device.
The use of household electrical and electronic appliances are safe.
It is necessary to check the proper grounding of large household appliances such as washer, dryer, stove and water heater.
The passage of patients through the security gates in stores is safe.
Prolonged stop in front of the theft systems should be avoided.
When traveling patients should demonstrate the identity of the device at the passenger control unit.
