Why does your heart have an abnormal beat? There are numerous factors that may contribute to your heart’s irregular pattern. When there is a disturbance in the flow and speed of your heart’s rhythm, ThedaCare experts go to work to find its source. An EP (electrophysiology) study will give our experts the means to identify the best course of action for your condition.

Your provider may recommend a pacemaker if you have an irregular heartbeat (also referred to as arrhythmia). This small device is implanted under the skin below your collarbone during a minor surgical procedure. Using leads (wires) that are guided from the device and into your heart, it sends electrical impulses and maintains a normal heart rhythm. You’ll be heavily or completely sedated during this procedure. Once the pacemaker is working, you likely won’t feel the electrical impulses.

Implantable Cardioverter Defibrillator (ICD)
Similar to a pacemaker, an implantable cardioverter defibrillator (ICD) constantly monitors your heart rate and rhythm. When your heart starts beating too fast, too slow or irregularly, an electrical signal is sent down the wires to shock the heart back into a normal rhythm. An ICD is recommended for people who have a serious arrhythmia, or who have suffered a cardiac arrest or heart attack and are at risk for cardiac arrest. This is a minor surgical procedure that requires you to be heavily or completely sedated, and involves the same implantation process as a pacemaker. You will most likely know when the ICD devise engages.

Ablation Therapy
Used to treat some types of heart rhythms, a catheter ablation is a procedure that involves placing a long, thin, flexible tube (called an ablation catheter) into a blood vessel in your arm, groin (upper thigh) or neck. The tube is then guided into your heart through the blood vessel and a special machine sends energy through the tube to your heart. This energy pinpoints small areas of heart tissue where abnormal heartbeats start.
