Every morning, or at least I try, I’d put on my Polar H10 chest strap heart rate monitor to record my HRV readings to try and make sense of how the readings were affected by the previous day’s work or training. This all started after I completed the Foundations of Heart Rate Variability Course a few months back, a pretty good course if I may add. The HRV readings are useful but the process of taking one less so. Imagine having to wake up, put on a chest strap HR monitor, then go back to lying down for a few minutes before recording the readings. So I was pretty stoked to hear that the founders of the Elite HRV app are crowdfunding to bring a dedicated HRV recording device called CorSense to reality.
So what is HRV actually? I’m lifting directly from the Kickstarter campaign since I can’t possibly explain better than what is already available.
“HRV is the change in time between successive heartbeats (also called inter-beat intervals, R-R intervals, N-N intervals, etc.). Unlike basic heart rate (HR) that counts the number of heartbeats per minute, HRV looks much closer at the tiny, millisecond fluctuations that occur between each heart beat in response to internal and external events.
HRV is a direct link to your Autonomic Nervous System and can therefore be used to gain insights into your nervous system, overall stress load and capacity to recover.”
So you can see why I make it a point to have my HRV measured every (most) mornings.
According to the Kickstarter campaign, the CorSense HRV reader will capture your HRV readings in just 2 minutes a day. The measuring device appears to be modeled after an oximeter in design; it’s small, highly portable and apparently fits fingers of all shapes and sizes. Plus the device runs up to 4 hours continuously on a single charge.
CorSense is apparently comparable in accuracy to a 5-lead EKG/ECG for HRV and pulse waveform, using multiple different LEDs, onboard algorithms and filters, fast sampling rates and physiologically optimized sensors.
The founders have also made the CorSense device compatible with 3rd party HRV recording apps with the option to export the data as well. This is nice since come of us are pretty used to our own HRV apps already.
I like how the CorSense looks and can imagine the ease of using it on a daily basis to capture my HRV readings.
The CorSense device will eventually retail at $145 but you can snag a unit at a significant discount if you back the project. At present, the CorSense campaign has already reached more than 50% of their goal with 28 more days to go.
