Informed Consent for Permanent Pacemaker Implantation
Informed Consent for Permanent Pacemaker Implantation
Patient and Facility Information
Nature and Purpose of the Procedure
A permanent cardiac pacemaker is a small battery-powered device implanted beneath the skin, typically in the left or right upper chest, just below the collarbone. The device monitors the heart's electrical activity and delivers precisely timed electrical impulses to maintain an adequate heart rate when the native rhythm is too slow (bradycardia), blocked, or otherwise abnormal. During the implantation procedure, one or more flexible, insulated wires called leads are advanced through the subclavian or cephalic vein and positioned within the appropriate chambers of the heart (right ventricle, right atrium, or left ventricle via the coronary sinus for cardiac resynchronization therapy). The generator is then connected to the leads and secured in a subcutaneous pocket. The procedure is performed under local anesthesia with intravenous sedation and typically takes 60 to 120 minutes.
Material Risks and Potential Complications
Reasonable Alternatives to Pacemaker Implantation
Anesthesia and Sedation
This procedure is performed under local anesthesia (lidocaine infiltration at the incision and pocket site) supplemented by intravenous conscious sedation (typically midazolam and fentanyl). General anesthesia is not routinely required. Sedation risks include respiratory depression, aspiration, and paradoxical reactions. The anesthesia plan will be reviewed separately with the anesthesia or procedural sedation team prior to the procedure.
Risks of Declining Treatment
If permanent pacemaker implantation is declined, the patient accepts the risks associated with untreated clinically significant bradycardia, which may include recurrent syncope or pre-syncope, falls and associated injuries, progressive heart failure due to chronotropic incompetence, and in high-degree or complete AV block, the risk of prolonged asystole and sudden cardiac death.
Expected Benefits
The primary expected benefit of permanent pacemaker implantation is reliable restoration and maintenance of an adequate heart rate, which is anticipated to resolve or substantially improve symptoms of bradycardia including syncope, pre-syncope, dizziness, fatigue, exercise intolerance, and shortness of breath. In patients with heart failure and dyssynchrony, cardiac resynchronization therapy (CRT) may additionally improve left ventricular ejection fraction, functional capacity, and quality of life. The device provides continuous cardiac monitoring capability and, in ICD-capable devices, protection against life-threatening ventricular arrhythmias.
MRI Conditionality Disclosure
The planned device is: [MRI-Conditional / Not MRI-Compatible]. If MRI-conditional, the device is approved for MRI scanning only under specific programmed conditions and field strength limits (typically 1.5 Tesla) as defined by the manufacturer. If not MRI-compatible, MRI scans are contraindicated and alternative imaging modalities (CT, ultrasound) must be used for future diagnostic workup. The patient must inform all future healthcare providers and imaging facilities of their implanted device before any imaging procedure. A device identification card will be issued following implantation and must be carried at all times.
Right to Refuse or Withdraw Consent
You have the right to refuse this procedure or withdraw your consent at any time before the procedure begins without penalty, loss of benefits, or adverse effect on your ongoing medical care. Your decision will not affect your relationship with your physician or access to other medical services. If you choose not to proceed, your care team will discuss alternative management plans with you.
Questions and Understanding Confirmation
I confirm that I have had the opportunity to read this consent form carefully and ask questions of my care team. All my questions have been answered to my satisfaction in language I understand. I have not been subjected to pressure or coercion in making this decision. I believe I am making an informed and voluntary decision.
Language Access and Interpreter Services
If English is not your primary language or if you require assistance communicating, a qualified medical interpreter is available to you at no cost. Please notify your care team immediately if you require interpreter services. You have the right to receive this consent document in your primary language or to have it read aloud to you by an interpreter before signing. Contact the Patient Services office for assistance.
Copy of Consent Acknowledgment
I acknowledge that I have been offered a signed copy of this informed consent form for my own records. I understand I may request an additional copy at any time from the facility or clinical records department.
Patient Declaration and Authorization
I, the undersigned, confirm that my cardiologist has explained the nature of the pacemaker implantation procedure, the expected benefits, the material risks listed above, the available alternatives, and the consequences of declining treatment. I have had the opportunity to ask questions and all my questions have been answered to my satisfaction. I understand that no guarantee of outcome has been made. I consent to the implantation of a permanent pacemaker and, if medically necessary, to any modified or extended procedures the surgical team deems necessary to achieve a safe and effective result. I also consent to the participation of supervised medical residents or fellows unless I have indicated otherwise in writing.
