One of the outstanding achievements of modern medicine is that people with malfunctions in life-sustaining organs can live almost completely normal lives without major impairments. One example of this is the cardiac pacemaker, which monitors the heart’s function and supports it as necessary. The key component is the pulse generator, which is implanted in the chest area. Two thin insulated wires (electrodes) connect the device to the heart and transmit the heart signal to the pulse generator.

This allows the pulse generator to continuously monitor the heart’s function and also deliver electrical impulses to the heart when it detects a rhythm that is too slow . These electrical signals stimulate the heart and cause it to beat faster. The pulse generator is powered by a battery  that usually lasts several years. The microprocessor  processes the data and can also record it for medical examinations. The capacitor   is of great importance: it stores the electrical energy required for the impulses.
