General review on cardiac implants and study of the methods for reducing electromagnetic interference (EMI).

Human heart can produce pulses and electrical impulses based on electrical specialized cells and with the use of sympathetic and parasympathetic nerves, these beats can also be adjusted. Cardiac arrhythmias and heart disease affect the electrical activity of the heart and impair cardiac function. Therefore, medical equipment and various therapies should be used to improve cardiac function. The pacemaker is designed to produce pulses and regular beats for those whose heart does not function properly and does not have regular beats. Pacemakers and cardiac implants have several types that are inserted into the body of cardiac patients. The main elements of the pacemakers include generators, batteries, and leads, which generator to produce pulses and batteries to power the device and finally, the pulses produced through the leads are sent to the heart. The pacemakers are divided into different types based on the number of leads and catheters, each of which has its own function
