ECG 12-Lead TLC500: Life-Saving Device for Advanced Heart Failure
I'm a middle-aged patient (not a doctor) with congenital (from birth) heart disease, but otherwise healthy. Due to systemic bias in cardiology, not recognising HFpEF (heart failure with preserved ejection fraction) or RHF (right-sided heart failure) on an equal footing as HFrEF (reduced EF) and LHF (left-sided heart failure), I was fighting a losing battle.
Despite numerous mechanical/structural and electrical issues, with stage4 RHF, two different Tier1 centres (for Adult Congenital Heart) dismissed my case as 'moderate' disease: 'no intervention required and symptoms not cardiology'!!
I used AI to study cardiology - enough to get a basic understanding to fight my case and understand how to get independent proof.
Step1: a medical-grade ECG. (For pacemaker detection we cannot use the cheaper consumer devices). Contec's device is 10,000 frequency, which is medical-grade and well-suited for my case.
A single run for a few hours was enough to get doctors scrambling, as I finally had evidence of critical and severe dysfunction. AI saw several screenshots and confirmed the device is high quality.
Fortunately I should now be able to get a pacemaker upgrade that will fix some of my issues. For this I'm incredibly grateful - it will likely expand lifespan too. Without - I'm at a critical stage. This is a genuine review - nobody would be so heartless as to make up this kind of tragic story.
Is the product perfect in every aspect? No. Let me also share the negatives:
1) Not necessarily Contec's fault, but I bought the device directly from a 3rd party, who must have sold an 'older box' with electrodes past expiry date - so the sticky part wears off and they fell off easily - my short-term fix was using sticky tape on top. But electrodes are cheap and easy to buy. AI advised me to try 3M electrodes instead.
2) Leads: They are about 0.9m. That's fine for lying still, or applying all leads top half of the body. But for my case, I needed a very accurate QRS interval - this meant placing the limb leads above wrists and ankles instead of just below neck and lower abdomen - so we need longer leads. There are some 3rd parties selling 2.8m, compatible ones, which I'll try next.
3) Software: I had to get several versions - the first one from that 3rd party, as well as the index code in the box were older, outdated versions. It was only at this point that I contacted Contec support directly. I dealt with 'Jimmy'. I'm telling you Jimmy was excellent - daily emails; he got me another software link; English was fine to understand and yes the software version he gave was fine. He even sent a video on use as the manual needs improving - certainly the English translation.
4) Software Interface: would benefit from an upgrade e.g. ditch the icons and replace with standard top level and second level menus. Also include X top right of every pop-up so that we can easily close any window, regardless of screen size.
In my case I needed overall averages and a few screenshots to pass to cardiology - this was enough
to get me, what should turn into life-saving treatment - hence this warrants a 5-star review.
I did notice multiple websites: different URLs for seemingly the same products. I do not believe this is any kind of 'scam'. My best guess: lack of 'SEO (software marketing) knowledge'. I work in software. Why do companies buy multiple URLs?
a) to stop competitors grabbing them
b) to limit spoofing as a security measure
c) for email campaigns.
Their mistake is not applying "301 .htaccess redirects" so that every url redirects to a single website, so that clients are clear.
