What is a Pacemaker?
A pacemaker is a small device implanted under the skin to help manage irregular heartbeats. It uses electrical pulses to prompt the heart to beat at a normal rate.
History of Pacemakers
The first pacemaker was implanted in 1958. Early pacemakers had external batteries, but by 1970, totally implantable devices were developed, drastically improving patients' quality of life.
Types of Pacemakers
There are three main types: single-chamber, dual-chamber, and biventricular. They differ by how many heart chambers they control, with biventricular pacemakers designed for heart failure patients.
Pacemaker Lifespan
Pacemakers don't last forever. Their batteries can last between 5 to 15 years, depending on usage. When battery life ends, a new device is usually implanted.
Living with a Pacemaker
Patients with pacemakers can live normal lives but must avoid strong electromagnetic fields. Regular check-ups are crucial to ensure the device functions properly.
Pacemaker and MRI Compatibility
Traditionally, pacemakers were considered a contraindication for MRI scans. However, recent advancements have seen the development of MRI-compatible pacemakers, broadening diagnostic options for patients.
Wireless Technology Advancements
The latest pacemakers now feature wireless technology, enabling remote monitoring by healthcare providers. This cutting-edge development allows for timely adjustments and improved patient care.
