Device Therapy for Atrial Fibrillation

Physicians affiliated with Memorial Hermann utilize implantable devices to treat patients suffering from atrial fibrillation (AFib).

Pacemaker

A pacemaker is a device, smaller than a matchbox, that is placed under the skin near the collarbone to help regulate a patient’s heartbeat. A wire extends from the pacemaker to the heart. If the pacemaker detects an abnormally slow heart rate (bradycardia) or the absence of a heartbeat, it emits electrical impulses that stimulate the heart to speed up or resume beating. A pacemaker is often implanted if medications to prevent arrhythmia or control the heart rate result in an excessively slow rate.  A pacemaker may also be implanted after Atrioventricular (AV) node ablation.

WATCHMAN

Patients at Memorial Hermann have access to the innovative WATCHMAN treatment that reduces the risk of stroke caused by non-valvular Afib. The WATCHMAN  is a small parachute-shaped device that permanently closes off the left atrial appendage, a site where clots can form and increase the risk of stroke. Implantation takes about an hour and once the device is implanted, it will not require replacement. In addition to reducing a patient’s risk of stroke, the WATCHMAN also eliminates the need for blood-thinning medications.
