Reference #7 provides an algorithm for identification of cardiac rhythm devices, which can facilitate this practical process.Įthical/Legal issues A patient’s/surrogate’s right to request withdrawal of life sustaining medical interventions, including pacemakers, is both legal and ethical. This is usually performed by a technician from the manufacturing company or an electrophysiology clinician.

While a trained radiologist or cardiologist may be able to discern the thicker RV lead and the visible coil of a CRT-D device on a chest x-ray, clinical distinction between CRT-D and CRT-P is best achieved by interrogating the device.

Downgrading does not affect the symptomatic benefits of pacing.

Indications for downgrade of CRT-D to CRT-P are evolving but often depend upon goals of care and prognosis.

♺ CRT-P cannot be upgraded to CRT-D without lead replacement however, a CRT-D may be downgraded to CRT-P in one of three ways: simple reprogramming generator replacement or placing a magnet over the generator (similar to an ICD). Most in the United States are of the CRT-D type. There are two main types: a) CRTs without capability for defibrillation (CRT-P) or b) CRTs with added capability for defibrillation (CRT-D). CRT devices deliver biventricular pacing to improve the efficiency and functionality of the right and left heart ventricles. ĬRT Devices These devices are used most often for patients with heart failure and, more rarely, in select patients with atrial fibrillation. When questions arise concerning dependency on the pacemaker, consult the cardiology/pacemaker service. In contrast to popular belief, it is rare that disabling the pacemaker will result in a swift and painless death as few patients are 100% pacemaker dependant, particularly during the period of imminent death (Fast Fact # 3), where tachycardia is the most common rhythm. In most other situations, deactivation is not indicated since the result is likely to be a symptomatic bradycardia, producing signs and symptoms of worsening heart failure (fatigue, dizziness, dyspnea). When is Pacemaker Deactivation Indicated? In patients with irreversible cognitive failure, where continued pacemaker activity is not meeting the goals of care, it may be appropriate to discuss the option of deactivation. At the time of death, the myocardium is usually too sick to respond to the pacemaker generated signals. In general, pacemakers do not keep dying patients alive, as terminal events are often due to sepsis, hemorrhage, pulmonary emboli, or arrhythmias from metabolic abnormalities associated with end-stage cancer, liver, or renal failure. However, a pacemaker is not a resuscitative device.

Pacemaker Function at Time of Death Patients and their families often make assumptions that pacemakers prolong the dying process and thus prolong suffering. Fast Fact #112 discusses implantable cardioverter-defibrillators. This Fast Fact discusses management of cardiac pacemakers at life’s end. Additionally, patients with congestive heart failure may receive biventricular pacemakers or cardiac resynchronization therapy devices (CRT) to improve symptoms.

heart block), more recently, patients with subvalvular stenosis, and atrial fibrillation may qualify for pacemakers. Although pacemakers were once primarily used to treat bradyarrhythmias (e.g. Over 600,000 new pacemakers are implanted each year, with most of these devices in patients over the age of 60.

Background Worldwide more than 3 million people have cardiac pacemakers.
