Electrophysiology Procedures at Stead Heart & Vascular Center
In most cases, EP testing and the Radio-frequency therapy performed during the same setting can cure the arrhythmia. The procedure takes approximately two to four hours to complete.
The purpose of an ICD is to save the life of the patient when SCA occurs. An implantable cardioverter defibrillator (ICD) is a device designed to terminate arrhythmias of the heart that if untreated would likely be lethal and restore normal rhythm quickly.
A typical schedule will include both clinical visits and telephone monitoring. Telephone monitoring utilizes specifically designed transmitter units that the staff to analyze how well the pacemaker is working while the patient is at home.
During a visit to the Pacemaker Clinic patients are seen by nursing professionals who check and record pulse and blood pressure, review current medications, inquire about symptoms such as sudden dizzy spells, lightheadedness, and fatigue and check the device insertion site.
Patients will receive an electrocardiogram and, using an electronic device, the nurses will interrogate or "read" information from the device to check for function and battery life and make any adjustments needed.
By identifying problems in advance, the medical staff at the Legacy Pacemaker Clinic is able to maximize pacemaker functioning. For example, patients who receive timely evaluations may find that they can prolong pacemaker life, anticipate and plan for their replacements when appropriate, and even identify changes in heart rhythms that necessitate pacemaker reprogramming.
A pacemaker is a small, battery-powered device that sends out weak electrical impulses that cause the heart muscle to contract. A pacemaker can be used to replace the function of the natural pacemaker of the heart when the heart is beating too slowly. It consists of wires (leads), which transmit electricity to the heart, and the pulse generator and battery, which generate the electrical impulses. The battery in a permanent pacemaker usually lasts 5 to 15 years. Your doctor will monitor your pacemaker regularly to decide when the battery should be changed.
Pacemakers are surgically placed into the chest (a permanent pacemaker) through a small incision. There are several types of implantable pacemakers.
A fixed-rate pacemaker gives off electrical impulses at a steady, regular rate, regardless of your level of activity. A rate-responsive pacemaker changes the rate of electrical impulses as your activity level changes.
- A single-chamber pacemaker controls only the lower chamber of the heart (ventricle).
- A dual-chamber pacemaker controls both the top (atrium) and bottom (ventricle) chambers of the heart.
- Many times the pacemaker is set to work only when the heart rate falls below a certain predetermined rate (demand mode).
Radiofrequency catheter ablation can also be used when persistent chronic atrial fibrillation does not respond to treatment with medication and symptoms continue to be bothersome. It is most often used in people who have difficult-to-control heart rates. The normal conduction area is ablated which then requires a pacemaker be implanted to maintain normal heart rhythm after the ablation. Ablation followed by pacemaker implantation reduces cardiac symptoms and improves exercise tolerance, quality of life, and the amount of blood pumped with each heartbeat.
