When someone s heart does not beat commonly, doctors use EPS to search out out why. Electrical signals typically travel through the heart during a regular pattern. Heart attacks, aging, and high blood pressure could cause scarring of the heart. this could cause the heart to beat in an irregular (uneven) pattern. Extra abnormal electrical pathways found in certain congenital heart defects can also cause arrhythmias.
An electrophysiology study (EPS) is a minimally invasive procedure that tests the electrical activity and the conductivity system of your heart. This check is used to search out out the reason for any rhythm disturbance to the heart and confirm the best treatment.
Examples of when an EPS is a helpful include:
1). Determining the reason for an abnormal heart rhythm
2). Locating the site of origin of an abnormal heart rhythm
3). Deciding the optimal treatment for an abnormal heart rhythm
4). Determining conductivity system disease.
At a hospital or clinic, doctors and nurses do EPS during a room that has special equipment for the tests. you may hear this room referred to as the electrophysiology laboratory or EP lab. Some call it the catheterization laboratory (cath lab). throughout the test:
1). A nurse will place an IV (intravenous line) in your arm. You will get medicine (a sedative) that will facilitate your relax. however, you ll be awake and ready to follow instructions throughout the check.
2). Your nurse will clean and shave the part of your body where the doctor will be working. this is typically in the groin however could be the arm or neck.
3). You ll be given a shot a neighborhood anesthetic will be given to creating the area numb. Your doctor will create a needle puncture through your skin and into your blood vessel. a tiny straw-sized tube referred to as a sheath will be inserted into your artery or vein. The doctor will gently guide many specialized EP catheters into your blood vessel through the sheath and advance them to your heart. A video screen will show the position of the catheters. you may feel some pressure in the area where the sheath was inserted, however you shouldn t feel any pain.
4). Your doctor will send little electric pulses through the catheters to create your heart beat at different speeds. you may feel your heart beat stronger or quicker.
5). Electrical signals produced by your heart will be picked up by the special catheters and recorded. this is referred to as cardiac mapping and permits the doctor to locate where arrhythmias are coming from,
6). Your doctor will remove the catheters and the IV line. Your nurse will place pressure on the puncture site to stop any bleeding.
7). EPS typically last one to four hours.
During an EPS, the doctor passes a thin, flexible wire through a vein in your upper thigh and occasionally the side of the neck to your heart. The wire records the hearts of electrical signals. Your doctor uses the wire to supply minute electrical impulses to the heart to cause the heart to beat in a specific sequence. These extra beats could cause your heart to go into arrhythmia. If an arrhythmia is produced, it often may be stopped by using another series of electrical impulses. Sometimes, if a serious heart rhythm is produced and you start to pass out an electrical shock to the chest will be given to convert the rhythm instantly back to general. Your doctor may also prefer to do a catheter ablation, a procedure used to fix some varieties of arrhythmia, throughout an EPS.
Most procedures are out-patient, lasting anyplace from 2-6 hours. Patients are asked to limit activity the primary twenty-four hours after the procedure. If the dressing over the groin wasn’t removed in the hospital, you can remove it the day after the procedure. At the location of insertion, you may notice a lump regarding the size of a walnut. this isn’t abnormal and can last for regarding 3 to 6 weeks after the swelling goes down. warm packs could facilitate to dissolve it more quickly. it’s conjointly general to experience some bruising around the insertion site. If the puncture sites still are painful or warm to the touch, show any signs of infection or become increasingly injured and tender, call your doctor.
