Application of integrated circuit in cardiac pacemaker

With the rapid development of technology, the application of integrated circuits in the field of medical equipment is becoming increasingly widespread, greatly promoting the progress of medical technology and the improvement of medical services. Among them, the pacemaker, as a typical medical device, has integrated a complex circuit system inside, realizing the monitoring and regulation of cardiac electrical signals, and bringing good news to patients with heart disease.

The pacemaker is an electronic device implanted in the body to treat heart diseases such as arrhythmia. It mainly consists of a pulse generator and electrode leads, among which the pulse generator is an outstanding representative of integrated circuit technology. The pulse generator integrates multiple circuit units such as a microprocessor, a memory, and a power management module. These circuit units work together to achieve real-time monitoring, analysis, and regulation of cardiac electrical signals.

Specifically, the pacemaker transmits electrical signals to the heart through electrode leads to monitor the electrical activity of the heart in real time. When the electrical signals of the heart are abnormal, the microprocessor will quickly make a judgment and adjust the output parameters of the pulse generator according to the preset treatment plan. By sending weak electrical pulses to stimulate the contraction of heart muscle, the pacemaker restores the normal rhythm of the heart.
