Frequently Asked Questions

Pacemaker implantation is performed under local anesthesia, so the area where the incision is made is numbed. Most patients do not experience significant pain during the procedure. However, some may feel pressure or discomfort during lead placement or when the leads are tested for proper function.

The procedure typically takes about 1 to 2 hours, but it can vary depending on individual circumstances and any additional procedures that may be performed concurrently.

Many CRT devices are now MRI compatible, but it's important to confirm with your healthcare provider if your specific device allows for MRI scans. Older devices may not be compatible, and precautions should be taken to ensure safety during MRI procedures. Discuss the MRI compatibility of your device with your doctor and the imaging facility before undergoing an MRI.

Recovery time can vary, but most patients can resume normal activities within a few days to a week after CRT implantation. It's important to follow your doctor's instructions regarding post-operative care, wound healing, and medication management.

Your healthcare provider will provide specific instructions for preparation, but generally: You may be asked to avoid eating or drinking for several hours before the procedure. Inform your doctor about any medications, allergies, or medical conditions you have. You may need to stop certain medications before the procedure, particularly blood thinners. Arrange for someone to drive you home after the procedure.

Device lead extraction is generally safe, but it does carry some risks and complications, including: Bleeding or hematoma at the extraction site. Damage to blood vessels or the heart during the extraction process. Infection. Arrhythmias or heart rhythm disturbances during or after the procedure. Rarely, the need for emergency open-heart surgery if complications arise.

Device lead extraction is typically performed in a specialized cardiac catheterization laboratory or operating room. It involves the use of specialized tools and techniques to carefully detach and remove the leads from the heart. The procedure may be done through a minimally invasive approach using laser or mechanical sheaths or, in more complex cases, may require open-heart surgery.

Electrical cardioversion is typically performed under sedation or general anesthesia, so patients do not feel the electric shock itself. However, some patients may experience discomfort or a brief sensation similar to being "thumped" in the chest. Pharmacological cardioversion does not involve direct pain but may have some side effects from the medications used.

Electrical cardioversion: An electric shock is delivered to the heart through paddles or patches placed on the chest. The shock interrupts the abnormal electrical activity in the heart and allows it to resume a normal rhythm. Pharmacological cardioversion: Medications, such as anti-arrhythmic drugs, are administered intravenously to restore the normal heart rhythm. This method is usually attempted before considering electrical cardioversion.

Patients are usually given local anesthesia and conscious sedation or general anesthesia to ensure comfort during the procedure. While the ablation itself is typically not painful, some patients may experience mild discomfort or a sensation of pressure when the catheter is positioned in the heart.
