Cardiac resynchronization therapy pacemakers (CRT-P) and defibrillators (CRT-D) are used to treat heart failure patients who have symptoms despite the best available drug therapy. These patients also have an electrical condition in which the lower chambers of the heart contract in an uncoordinated way and a mechanical condition in which the heart pumps less blood than normal. CRT-Ps and CRT-Ds are not for everyone including people with separate implantable cardioverter-defibrillators (CRT-P only) or certain steroid allergies. Procedure risks include infection, tissue damage, and kidney failure. In some cases, the device may be unable to respond to your heart rhythm (CRT-P only) or may be unable to respond to irregular heartbeats or may deliver inappropriate shocks (CRT-D only). In rare cases severe complications or device failures can occur. Electrical or magnetic fields can affect the device. Only your doctor knows what is right for you. These devices are available by prescription only. Individual results may vary.
An implantable cardioverter defibrillator can protect you from the effects of sudden cardiac arrest by reviving your heart rhythm. But it is not for everyone, including people with certain steroid allergies. Procedure risks include infection and tissue damage. In some cases, the device may not respond to irregular heartbeats or may deliver inappropriate shocks. In rare cases severe complications or device failures can occur. Electrical or magnetic fields can affect the device. Only your cardiologist knows what is right for you. This device is available by prescription only. Individual results may vary.
A pacemaker system can monitor and treat your heart rhythm by delivering electrical energy to pace your heart when it senses a slow rhythm. But it is not for everyone, including patients with certain steroid allergies. Patients who have additional medical conditions that may not allow the pacemaker to function appropriately should not receive a device. Procedure risks include infection, tissue damage and kidney failure. In some cases, the device may not respond to your heart rhythm. In rare cases severe complications or device failures can occur. Electrical or magnetic fields can affect the device. Only your doctor knows what is right for you. This device is available by prescription only. Individual results may vary.
