As explained in the Electrophysiology section, one area we specialize in is the electrical system of the heart. The electrical signals of the heart keep the heart beating and the blood flowing in a specific rhythm. A device, such as a pacemaker or implantable cardiac defibrillator (ICD), can be implanted to assist your heart to beat in the correct interval. A pacemaker acts as a safety net to ensure the heart rate does not fall below a certain rate, as well as regulates the interval between impulses so they are not too far apart. The cardioverter defibrillator may be implanted for those with a weakened heart, which can be the cause of ventricular fibrillation, a potentially life threatening arrhythmia. A cardioverter defibrillator is also indicated for those who have experienced ventricular fibrillation previously. These devices need to be checked regularly to evaluate the battery life and to check that the device and leads are functioning well. Sometimes heart failure and arrhythmias can be monitored with regular device checks also. It is recommended to have your device checked every 3 months. While in-office checks can be performed every 3 months, you may also have the option of getting your device checked remotely, only needing to come in our office annually for a check. When scheduled for a device check, you will be monitored by either one of our Cardiovascular Technicians or a representative from the company of the individual device you have.
