Single-chamber ICDs Are Safer, But Some Patients Need More
Research suggests that the simpler devices are just as effective as the more complicated ICDs at preventing sudden cardiac death.
If your heart requires an implantable cardioverter defibrillator (ICD) to prevent sudden cardiac death, as well as a pacemaker to help maintain a steady rhythm, youíre likely to be recommended for a dual-chamber or dual-lead ICD. Such devices have leads going to the upper and lower chambers of the heart. If you donít need the assistance of a pacemaker, you may be advised to get a single-chamber or single-lead ICD. These devices are life-savers, but they can be complicated.
