Unclassified readings

[Norvette]

I started getting only unclassified readings on my Alivecor monitor. I have this monitor because I'm in and out of AFib right now in flutter . So it's very important to have a good reading. I found that if I delete the readings in memory it started reading correctly again. I just wanted to pass this along.

sometimes it seems to be unclassified if the pulse rate is either too slow or too fast too

I doubt at all the past recordings are having any effect at all. These recordings will provide good background comparisons and data.

Personally I would not delete at all.

'Unclassified' is not a technical fail. It just means that there is something going in your ECG on that doesn't fall into a neat category like AF.

(The Kardia has a few categories like AF because they know that is a useful thing to look out for. However, there are more things than AF to think of, and there is always new knowledge and new hearts that don't fit the norm).

My Unclassified readings have been very useful, they draw attention to when my heart is misbehaving. It is on the base of one of these that I got my GP's attention and a referral to an EP.

(Actually, as an example for you, in my case they showed that I am having runs of multiple ventricular ectopics — out of the accepted normal range, with multiple morphologies, therefore worth seeking a medical opinion. My GP thinks so).

If you can spare a fiver, it is well worth sending one of these off to get analysed by a doctor. Then you can see why the reading is 'Unclassified'.

I have got 'unclassified' when the number of ectopics, both PVC's and PAC's, triggers it, when there is sinus arrhythmia caused by breathing in and out and when I have runs of tachycardia such as AFlutter. Your stored traces cannot influence the performance of a live reading, so it must be coincidence that readings return to normal after deletion - unless you have a peculiar setting somewhere.

It could be a coincidence. However the last 15 recordings have been unclassified even when my wife used it that comes out normal came out unclassified. Now hers is coming out normal and mine as possible Afib. If it's a coincidence, it's working now I can live with it.

I did a survey just recently mainly to find out what unclassified meant for the Alivecore device; here is the reply { no names included for privacy }-

Thank you for completing our survey!

We currently have 3 detectors: Possible Afib, Normal or Unreadable. If neither of those 3 can be detected, then you will receive the message, Unclassified.

To receive a Normal Detector:

If no abnormalities are detected, you will receive the message “Normal. No abnormalities were detected in your ECG”. This means that the heart rate is between 50 and 100 BPM, there are no or very few abnormal beats, and the shape, timing and duration of each beat is considered normal. It is important to remember that there is a wide range of normal variability among different individuals. Changes in the shape or timing of an ECG might be normal for a single individual, but since the Kardia Mobile is used by a large and diverse population, the Normal Detector has been designed to be conservative with what it detects as normal.

If you have been diagnosed with a condition that affects the shape of your ECG (e.g., intraventricular conduction delay, left or right bundle branch block, Wolff-Parkinson-White Syndrome, etc.), experience a large number of premature ventricular or atrial contractions (PVC and PAC), are experiencing an arrhythmia, or took a poor quality recording it is unlikely that you will be notified that your ECG is normal.

It is also important to note that the Normal Detector looks at the entire signal before determining if it can be declared to be normal. If you experience a small number of PACs or PVCs in a recording of otherwise normal beats in normal rhythm, the Normal Detector will likely declare this recording to be normal.

If you have any additional questions, please do not hesitate to reach out.

Kind Regards,

Thanks ultramarine , that's really useful!

Email all your past recordings to yourself then remove the app and reinstall ....it sorted my alivecor glitches since the latest update

[PeterWh in reply to bushy2016]

You don't need to do that since all the data is stored on the Kardia (AliveCor) server. You can always log on from a PC and you will see it there. It's much easier going back om past ones than on a phone. I am almost certain that uninstalling the App will not delete any recordings. You can double check on the Kardia website or if it isn't in FAQ then you can always email them.

[bushy2016 in reply to PeterWh]

it clears the data off the phone, but your right they are on the kardia server and I like to send them via email as it is another way to save and access fast from your phone
