Basically, it is a tiny insertable cardiac monitor that is placed subcutaneously between 3rd and 4th rib in the chest. It is about one-third the size of a AAA battery. It is called a loop recorder - which means that it records so much and then records over that. So basically, I have a 24/7 ECG inserted in my chest. I have a monitor that is at my bedside. Every night while I am asleep, the device inside me communicates with the patient monitor which is then uploaded to my physician's office. He has software that reports certain activities -- depending on how my device is programmed. It is an excellent diagnostic tool for people who experience intermittent arrhythmias, syncopal episodes or atrial fibrillation. It can be implanted for about 3 years which is the length of the battery life. If you need an MRI done, you can still get one with some special adjustments. I also have a little device which is called a Patient Assistant. If I am experiencing symptoms that I am concerned about -- I just hold the Patient Assistant over the implant and push the button. What this does is mark the reading on the device. So when the information is uploaded, it will be marked. Then I have to contact the doctor's office and let them know what I was experiencing at that time. The doctor then looks at the reading for that time period to see if the symptoms were related to an arrhythmia. The cost is about $20,000 currently but insurance does cover it. The reason it is so high is because they are most often implanted as an outpatient surgery in a hospital. My doctor is working on getting set up to do them in the office which would be a tremendous saving to the patient. The procedure to insert it is very simple -- only requiring local anesthesia. I only had to pay 10 percent so I felt like it was a cost-effective tool in my case -- to have my cardiologist monitor my heart closely for three years. The only other cost is a quarterly cost of about $120 for my physician to interpret my readings. I had a 30 day event monitor placed earlier this year -- and of course, during that 30 day period, my heart didn't have the new worrisome episodes.
