Kardimobile KARDIMOBILE 6-LEAD KARDIMOBILE 6-LEAD Blac (Open Box)

I have an Apple Watch, 2 automatic blood pressure devices that record heart rate, and an oximeter that measures both oxygen concentrations and pulse. I need to know if I am in atrial fibrillation and more importantly - what the ventricular rate is. I had a recent cardiac procedure and for the first time realized that the watch and the blood pressure devices may have been measuring the atrial rate rather than the ventricular rate. The first sign I had of that was my palpable carotid pulse and the oximeter pulse were about half as much as what the watch and BP devices were measuring. The difference between atrial and ventricular rates on a regular 12-lead ECG are obvious. When I heard that Kardia had a 6-lead ECG that was inexpensive and easy to use at home - I decided to try it. The credit card sized device is easy to use. It does take some practice to record smooth wave forms but that is no different than the Apple Watch. 30 second ECGs are recorded and easily converted to PDFs that can immediately be emailed to your doctor or clinic. I was recording and emailing them within 10 minutes of opening the box. I have included an image of an ECG tracing I made on September 15, 2023 showing normal sinus rhythm. The only downsides I have noted so far are minor and they include: 1: Extra services are for sale including additional algorithms for ECG interpretation. I can read ECGs so I did not consider that to be a big issue. It might be for a person who wants more than the very basic readings that do include atrial fibrillation. You can also consult with a Cardiologist through this app for a fee. 2: Deleting ECGs - the app gives you the choice to accept or rerecord ECGs during the initial save step. If you do save - there is no way that I can figure out to delete the files. It is easy to rapidly accumulate a large file of ECGs and I have not figured out how much memory these files are using. There are online instructions on how to delete the files but they do not appear to work for this specific device. 3: Getting used to doing the recording - to do the 6 lead ECG you needs to hold the device between the finger and thumb of your right and left hands and against the knee or ankle area of your left leg. If you waver too drastically the recording is rejected and you have to try again. A 6-lead ECG doesn't have chest leads - all of that information is not there. Regular 12-lead machine run by a tech is less likely to have significant artifacts so signal to noise is greater with a 12-lead ECG. Bundled into the cost of the 12 lead is a more extensive algorithm and a cardiologist read of the tracing. It is also important to remember that the ECG contains a lot of information and expertise interpreting it. In my opinion it is best to use it in collaboration with a physician who is following a known problem or suspects a problem rather than to think that it can be used as an independent diagnostic tool. All things considered this is a very innovative, practical, and easy to use device that produced superior recordings at home that can be used by your personal physicians.
