My Cardiac Issues in a Nutshell
About ten years ago, I had a very unusual experience in which I fell asleep sitting up in a chair while my three children played nearby in our above-ground pool.
The last thing I remember was hearing the joyful sounds of chatter water splattering as they played. Hours later, I woke suddenly to unnerving quiet and the sun going down, displaying a beautiful sunset. Why was that unnerving? I am not the type to just fall asleep that easily, and I had never fallen asleep sitting up in a chair—until that day.
My children thought that I was just taking a well-deserved nap and so decided to leave me sleeping while they came inside to clean up from their swimming. None of them were worried that something might be wrong.
I headed to the emergency room, where it was determined, after several hours, that I had arrhythmia. I was extremely exhausted, and I was told that due to the extremely fast heartbeat that I exhibited when I arrived, it was like running a marathon, which would explain the fatigue. I was sent to my doctor and a cardiologist the next day.
I would often feel a faint fluttering in my chest, but no doctor was able to detect it before. This ER visit, however, provided hope that maybe someone would finally figure out what was going on.
After meeting with my doctor and having another ECG done, the test results came back normal—but I knew something was going on. Wearing a Holter monitor was suggested. The monitoring revealed a rapid heartbeat of 248 beats per minute on occasion. During this period, I woke suddenly to investigate the rattling that I heard under the bed. I just knew that there was a rattlesnake under the bed. It was revealed that the rapid heartbeat of 248 beats per minute coincided with the rattle that I heard "under the bed."
I was tried on several medications until my cardiologist suggested that I think about getting an implantable cardiac monitor. After much discussion and being able to see an actual device, I went ahead with the surgery. I did not experience any major complications from the implant procedure. I did have some mild reactions to the surgical tape and bandage at the surgical site.
Now, whenever I experience an "event," I immediately place the patient assistant over the device site and press the button. Enough of these episodes have given my cardiologist enough information to diagnose SVT (super-ventricular tachycardia). I am still being monitored for these episodes. He prescribed medication to control the condition, but the arrhythmia persists.
In about two months, it will be a year since I have had the implant, but we have already discussed having an EP (electrophysiology) study done.
Well, that's my story in a nutshell. You can hear more about it in my video posted at the end of this article.
What Is the Implantable Cardiac Loop Recorder?
The loop recorder can be referred to as an:
- insertable cardiac monitor
- insertable loop recorder (ILR)
- insertable cardiac
Implantable loop recorders (ILRs) are:
Read More From Patientslounge
- small lead-less boxes
- about 6.5-9 mL in volume (the size of a standard memory stick)
- have two self-contained electrodes that are implanted subcutaneously under local anesthesia, typically in a left parasternal location
- Current ILR devices have a battery life of up to three years.
The implantable cardiac device is a device about the size of a flash drive (maybe a little smaller) that continuously monitors heart rhythms and records them either automatically or when you use a hand-held patient assistant. The hand-held assistant allows the patient to mark the occurrence of an episode so that the Cardiologist will be aware of when one is felt.
The ILR device:
- makes a record of your electrocardiogram (ECG or EKG) when you have fast or slow heartbeats
- monitors your heart continuously based on what the doctor programs
- when you feel dizzy or like you want to faint
- can be used to see how you respond to different medicines
The Implantable Cardiac Loop Recorder
How Does The Reveal Implantable Loop Recorder Work?
The ILR continuously monitors the rate and rhythm of the heart.
It works much like a black box in an airplane, whereby
- vital information is recorded and can be played back later for detailed analysis
- it can continuously record the heart’s rhythm and rate for up to 3 years
- it can help to determine if unexplained transient symptoms are related to a heart rhythm problem in up to 88 percent of cases, a diagnostic yield much higher than traditional methods. (Source: American Journal of Cardiology, 1998)
To store the electrocardiogram (ECG) at the time of the episode, I simply place a hand-held, pager-sized activator, called the Patient Assistant over the Reveal ILR site after or during an episode, and press a button. The button will be blue, and when the episode has been recorded, it changes to green.
If I am unconscious, a family member or friend also can be the one to place the activator over the device to save the information. Later, a physician analyzes the stored information and determines whether the episode was caused by an abnormal heart rhythm.
Using the Patient Assistant
When Would an Implantable Cardiac Monitor Be Recommended?
An ILR would be considered in the following instances:
- For evaluation of recurrent unexplained episodes of pre-syncope, syncope, seizures, palpitations, or dizziness
- A cardiac arrhythmia is suspected as the cause of the symptoms
- For persons with heart failure, prior myocardial infarction, or significant ECG abnormalities
- Noninvasive ambulatory monitoring, consisting of 30-day pre-symptom external loop recordings or MCT (Mobile Cardiovascular Telemetry), fails to establish a definitive diagnosis
- For persons without heart failure, prior myocardial infarction, or significant ECG abnormalities, symptoms occur so infrequently and unpredictably (less frequently than once per month) that noninvasive ambulatory monitoring (MCT or external loop recorders) is unlikely to capture a diagnostic ECG.
- For evaluation of members with suspected atrial fibrillation as a cause of cryptogenic stroke who have had a non-diagnostic Holter monitor.
Placement Of The Device
The Surgery: How Is The Cardiac Loop Recorder Implanted?
Placement of an implantable loop recorder (ILR):
- can be performed in any standard procedure suite
- is typically inserted in the left parasternal region.
Prophylactic antibiotics are administered intravenously before the incision is made.
Under sterile conditions, the creation of a small subcutaneous pocket using local anesthesia is required.
A mild anxiolytic and/or analgesic can also be administered to enhance patient comfort.
Implanting the ILR
- takes about 15 to 20 minutes
- can be done under a local anesthetic
The physician makes an incision about two centimeters in length, creating a pocket the same size and shape as the ILR device, about the size of a pack of gum.
Once the device is inserted in the pocket, it is programmed to record the ECG during an episode.
When heart activity is recorded during an actual episode, and the physician is satisfied that heart rhythm-related causes can be ruled in or out, the device can be removed.
My Ticker Is Always Being Watched!
Having a loop monitor implanted is like being on a leash and being under 24-hour surveillance!
WARNING: The Linq Reveal implanted cardiac monitor records 24 hours a day. By having this recorder implanted, you agree to have everything about your heart monitored. That means you have to provide a reason for each time your heart rate increased. Why exactly are you rock climbing?
It's a good thing, though. My ticker is always being watched. Gotta love technology!
What Is This Device Telling the Cardiologist?
- If the medicines are working
- If a pacemaker or an implantable cardioverter defibrillator (ICD) is working properly
- Why you have symptoms such as chest pain, dizziness, faintness, or the feeling that your heart is racing or skipping a beat
- If your heart is getting enough oxygen to meet its needs.
- If you're at risk for atrial fibrillation
What Are the Treatment Options If the Cause Is Determined To Be Heart-Related?
When the cause of the episodes is properly determined, it can usually be treated.
- If the episodes are caused by an abnormal heart rhythm, treatment options include medication
- a pacemaker
- implantable cardioverter defibrillator (ICD)
- catheter ablation
After these treatments, patients can often resume normal activities without fear of suffering another episode. Such treatments not only may eliminate the episodes but may also correct the underlying cause, which could result in better overall health and improved quality of life for patients.
What's Next for Me?
In a few weeks, I will meet with my cardiologist to discuss the Cardiac Ablation procedure and the possible implantation of a pacemaker. It is unclear at this point if the loop recorder will be removed or if it will be allowed to stay in to continue to monitor me long-term.
Catheter ablation, also called radiofrequency or pulmonary vein ablation, isn’t surgery, and it’s the least invasive option. My cardiologist will put a thin, flexible tube into a blood vessel in the leg. Then, it's guided to my heart.
This procedure destroys the tissue that may be causing the heartbeat to get off course. This creates scar tissue inside the heart’s chambers. This scar tissue is a good thing. It will help the heartbeat stay in rhythm.
The doctor uses heat, cold, or radio energy to scar some tissue inside the heart, where the irregular beats are triggered. The treated tissue helps regulate the heartbeat again.

i have. had an ILR for past 4 years and i am about to go for my surgery to remove it as the battery has run out.doctors havent identified the cause at all still but hope they do soon. its good to hear stories from people who have had different experiences and seeing it so positively. wishing you good health. stay blessed

In 2007 I wore a 24 holter monitor which revealed I had 20,000 PVCs in 24 hours. I had a cardiac ablation using radio waves. It was not a difficult thing to go thru. My PVCs did not return. In 2012, 2013 I was feeling short of breath, dizzy, and felt rapid heart beats. Nothing was ever caught on EKG. A loop recorder was put in in 2014. A very easily tolerated procedure. I was found to have infrequent runs of short duration of SVTs. No AFIB which was what I was afraid of finding. Now I know what those infrequent periods of fast heart rate really are. All figured out by this little recorder. It is well worth getting one.

Gina, my heart just breaks for you. You're so young! But not only are you beautiful, you're one of the bravest, most positive women I've come across.

Hi Manatita. Thanks for stopping by and for your detailed comment.
I understand the concern with medications and herbs. I am under the care of both medical doctors as well as a Master Herbalist, and thank God, so far there have been no complications.
I've been informed that the ablation should alleviate the need for medications after this. This is good news as taking meds for life (my other option) is not appealing to me. The pacemaker will also help.
YouTube has provided me with quite a few videos about others experiences with the ablation as well as the pacemaker so I will go in to my next appointment well informed.
Thanks again for dropping in. I've seen some of your new poetry, but I need to stay longer to comment. Loving them!

You're very brave, Gina. This is a major problem and frankly I don't know why you have not hard the Ablation or the ICD as yet. Your heart beat is way too fast and too frequent, to simply monitor you so long.
Of course for any cardiologist, history-taking and medications are important, but you seem to have had some 'black-outs' as well for what could be AF and I'm amazed that they haven't taken it further. Good that they are seeing your recorded events, though. Rather like a home telemetry.
Ablation has it's pros and cons like everything else, and they would give you the patient leaflet. You can also see it online or get details and video from the American equivalent of the British Heart Foundation. My friend had one 3 years ago for AF and is still doing well.
Be careful with mixing medicines, especially the Lupus ones as they can also interact with herbs. You will read a lot about herbs being natural and without side-effects. Not true. Anything can harm us, allopathic or non-allopathic. Continue to be careful, watchful!
A well-written and informative article. Much Love.
A well written article and video. Watch your 'stressors' and be as pro-active as you can with them, in a loving way.
