Cardiac pacemakers are medical devices implanted in the body to regulate abnormal heart rhythms, primarily by delivering electrical impulses to the heart muscle. They are crucial for patients with arrhythmias, ensuring the heart maintains a rhythm that supports adequate blood flow throughout the body.

Cardiac Pacemakers

Medical devices are instruments, machines, implants, or related articles used to diagnose, prevent, or treat diseases and other medical conditions without primarily relying on chemical action within or on the body. They range from simple tools like thermometers to complex machinery like MRI machines, and their development and regulation are critical to ensuring safety and efficacy in healthcare.

Abnormal heart rhythms

Electrical impulses are rapid signals transmitted along the nerve fibers, enabling communication between neurons and other cells. They are crucial for the functioning of the nervous system, facilitating responses to stimuli and coordination of bodily functions.

Electrical Impulses

Patients with arrhythmias

Heart rhythm refers to the pattern of electrical impulses that regulate the heartbeat, ensuring the heart contracts and relaxes in a coordinated manner. Anomalies in heart rhythm, known as arrhythmias, can lead to various health issues, ranging from benign to life-threatening conditions.
