If you have a condition called bradycardia, otherwise known as a slow heartbeat, you and your doctor may decide an implantable heart device called a pacemaker is the right option for you. A pacemaker helps restore the heart's rhythm, by sending tiny electrical signals to the heart to increase the heart rate, which relieves the symptoms of bradycardia.
When people refer to a pacemaker, they are actually discussing a pacing system, which includes the pacemaker and leads:
A pacemaker is designed to mimic the heart’s natural pacemaker, the sinus node. The pacemaker has two main purposes: pacing and sensing.
A pacemaker will send an electrical impulse to the heart when the heart’s own rhythm is too slow or is interrupted. This electrical impulse starts a heartbeat.
A pacemaker will also “sense” (monitor) the heart’s natural electrical activity. When the pacemaker senses a natural heartbeat, it will not deliver a pacing pulse.
A leadless pacemaker is 93% smaller than traditional pacemakers.1 It is the size of a large vitamin capsule and has a battery that typically lasts between 8 and 13 years.2,3 Unlike a standard pacemaker, it is implanted into the heart through a vein in your leg and does not require a lead. The device’s miniaturized size and minimally invasive approach leaves no visible sign of a medical device under the skin. This can mean fewer post-implant activity restrictions and no obstructions to shoulder movement.
A leadless pacemaker is intended for patients with specific pacing needs. Talk with your doctor about the benefits and risks of a leadless pacemaker.
A smartphone connected pacemaker communicates directly and securely with the MyCareLink Heart™ mobile app on your mobile device. The MyCareLink Heart mobile app allows you to stay connected to your clinic, providing peace of mind and freedom, so you can continue living your life — uninterrupted.
Peace of mind
A smartphone connected pacemaker features the latest innovation in pacing technology. With over 13 years of battery life, it will maintain its safety and dependability for many years. It also offers exclusive features proven to accurately detect and significantly reduce your risk* of developing persistent atrial fibrillation (AF) associated with an increased risk of stroke.
