What are two common types of devices used for rhythm control in atrial fibrillation?

In the management of atrial fibrillation, rhythm control strategies aim to restore and maintain a normal heart rhythm. Among the devices available for this purpose, implantable cardioverter-defibrillators (ICDs) and pacemakers play significant roles.

ICDs are used primarily for patients at high risk of life-threatening arrhythmias, providing both monitoring and the ability to deliver shocks to correct rapid heart rhythms. While they are not solely focused on atrial fibrillation, their ability to manage multiple arrhythmias makes them a vital option in complex cases.

Pacemakers are another critical device used in the context of atrial fibrillation. They help regulate the heart rate by providing electrical stimulation when the heart's natural pacing is inadequate, particularly after other rhythm control strategies have failed or in cases of bradycardia. They help ensure the heart maintains a proper rate, thereby contributing to overall rhythm management.

While other treatment options like beta-blockers, anticoagulants, and calcium channel blockers play essential roles in managing atrial fibrillation and its symptoms, they are not classified as devices. Hence, they do not fit the criteria of "devices" for rhythm control in this context.
