Some may wonder why my regular 5 to 8 daily posts suddenly dried up 4 days back (and some may not which is all fine as I prefer to focus on tech stuff and not my own daily lessons in life). For the second time in 32 years I was hit by an extreme viral infection (only detected by high fever and blood tests). This time around though I was wearing a Fitbit with 24/7 heart rate monitoring, so I've got some tech stuff to dig into now while I recuperate. The future of wearables is not just about tracking fitness, it also needs to be about early detection and identifying disease and illness from the patterns detected, whether at rest or while exercising. There is a wealth of big data sitting with Garmin, Fitbit, Polar, Jawbone, and others which include current heart rate, resting heart rate, perspiration, temperature, altitude, sleep patterns, state of activity, etc. Matching this to known patterns over time could be extremely useful. In my own case I can now see the small dip in resting heart rate just before the symptoms struck (about 6+ hours). And if I had bothered (I did not feel like it later on) to confirm by Saturday I would have seen the alarming increase in my resting heart rate (I was in bed and not walking around) and may not have waited to Sunday to check into hospital (I have an idiosyncrasy in that I rarely know when I'm ill as my heart rate is usually on the higher side and if I have a rare headache it is usually from blocked sinuses and hayfever). The question though really is, there is all this health data tied up in proprietary databases, and the data is getting better and better, but is there any serious drive towards it being available for mass analysis? Fitbit for example does not even have an "activity" classed as "illness" where we could enter details eg. flu, cold, etc. It just seems such a waste of data collection and not at all in the public good? In many industries the cost of doing business includes either a payment to some central fund (levy like tobacco or fuel) or otherwise the provision of statistics. How come the fitness tracking market does not have to contribute anything except income tax? Health and fighting disease should be a public priority and we should all be standing together, not separating around profit and locking others out. I know there are some initiatives like Achu, which I just deleted now as it gave zero indication to me despite me sharing my data to their app.
Monday heart rate with medication taking affect
Monday I was on drips with antibiotics and painkillers, in between visits for head, chest, and abdomen scans.
Resting heart rate for the past month
Shows a very sharp spike the last few days. The dip just before the sharp rise is on Thursday 24 March, and the rise starts on Fri 25 March. I was still feeling fine Friday evening when I had supper. After the illness kicked in I ate nothing and only managed a little water up to Sunday about 16:00, when I went to hospital. Despite this seeming quite severe it wa snot my worst. Back in February 1985 a similar viral infection hit me and my temperature hit 105F (40.5C) so that I could not actually even go to hospital. This time around I clocked about 39 point something degrees C. The other difference was way more scanning and analysis is now available so we are hoping to learn something from the blood cultures. What got me admitted as a blood reading that was supposed to show less than 5, and my reading was 180. I'm getting more detail on that still now that I can think a bit more clearly.
Friday just before illness - normal hear rate
Friday - normal day shows low bpm while sleeping and higher activity in the day (mine is always high in the day)
Sunday heart rate as illness escalated
Sunday illness was escalating and you can see from midnight through early morning my BPM was around 110 - 115 and by late afternoon (when I checked into hospital) it was hitting 142 BPM (while lying in bed). The drops later was while I was on a drip in casualty, which wore off while they were waiting for the blood tests around 21:00. I was admitted into hospital about 23:15.
Saturday heart rate as illness symptoms started
Saturday when I became ill - can see my morning sleep bpm was quite erratic and even peaked at about 90 bpm while sleeping. Although there was high bpm in the day I was feeling ill and lay in bed the whole day, yet it hit above 117 bpm.
Tuesday heart rtae with fever mostly passed
Tuesday the fever had actually passed most of its effect so you can see that BPM rate coming right down (especially whilst still on the drip). I checked out of hospital in late afternoon and this shows my more normal day time geart rate (except I was not moving around quickly like I do at work). The peak at abut 23:00 was a severe hayfever attack (that's another story).
