Pacemakers are used to control problems pertaining to heart failures,heart surgeries and heart attacks.They are also used to record and track heartbeats and all pacemakers are not permanently fixed, some are used during surgeries and medication overdose which slows down our heart.
Pacemakers are implanted by surgeons and the operation takes 1-2 hours and they are mostly placed under the collarbone. They weigh as less as 20-50grams and are smaller than a matchbox.Pacemakers have one lead single chamber pacemaker,two leads called dual chamber pacemaker and biventricular pacemakers.several tests are done before placing a pacemaker.ECG or echocardiogram which uses sound waves is used by doctors to measure the size and thickness of heart muscles, they place sensors on the skin which measures the electrical signals. A wearable device tracking our heart rhythm for many hours is Holter monitoring and stress tests are done to track heart rate while exercising.
Like other surgeries there are some complications associated with surgical installation of pacemakers. With regular follow ups with the doctor we can minimize life threateningrisks. Modern pacemakers are not as sensitive as the old ones to electrical devices, but care should be taken to avoid causing interference with pacemaker.Mobile phones,MP3 players should not be placed in shirt pockets, exposure to metal detectors and standing near microwaves or high- voltage transformers may affect the functioning of pacemakers.
