A pacemaker is a medical device that transmits tiny electrical impulses to the cardiac muscles to keep the heart rate in a healthy range or to activate the lower chamber of the heart. Syncope, heart problems, and hypertrophic cardiomyopathy are among the conditions that can be treated with this drug. The pacemaker is put by a minimally invasive surgical procedure called epicardial or endocardial. The cables and pacemaker are implanted through an incision in the patient's chest. Pacemakers are medical equipment that detects irregular cardiac rhythms and are implanted in the chest and abdomen. It is being used to treat arrhythmia, a condition in which the heart beats too quickly, too slowly, or in an irregular rhythm. Electric pulses are generated by pacemakers to keep the heart beating at a normal rate. Pacemakers can be implanted in the body either temporarily or permanently. To secure it from electrical waves, a fixed pacemaker is encased in a metal casing. Temporary pacing can take the form of transcutaneous, intravenous, or epicardial pacing.
