Electrocardiogram verification

A cardiac pacemaker is a small, thin, battery-powered implantable electronic device that detects when the heart beats irregularly or too slowly. It sends electrical impulses to the heart to help regulate and maintain an appropriate heart rate and rhythm.

However, these devices do not last indefinitely, which is why their function must be monitored and adjusted when necessary.

Regardless of the type of cardiac device implanted, whether it is a pacemaker, an implantable cardioverter-defibrillator (ICD), a cardiac resynchronization therapy (CRT) device for heart failure, or an implantable cardiac event recorder, regular device checks are essential to ensure effective performance. These evaluations should be performed every one to two years.

During the examination, the basic parameters of the cardiac device are assessed. Possible episodes of cardiac arrhythmia, including their nature and duration, are reviewed, and if necessary, prescribed medication is adjusted or a new treatment plan is initiated.

Modern pacemakers typically function for 8 to 12 years, depending on how frequently the device needs to deliver electrical impulses and how long it can monitor the heart's intrinsic activity. Since the device cannot be disassembled and its battery cannot be recharged, a minor surgical procedure is performed when the battery reaches the end of its lifespan, and the pacemaker is replaced with a new one.
