The episodes last about 10 seconds. These show up as sharp downward spikes on the graph. These are during "off" intervals, occasionally during easy "on" intervals—in other words, when I'm not under a lot of load. This is with a chest-band HRM that I believe is maintaining good contact—I don't think it's an equipment problem.
Is this a cause for concern? Anyone else see this?
Just wondering if you ever figured this out? I experience the same issue. I know it is not a technical or equipment issue because I can feel it coming on before it starts, hard to describe but it is like my stomach drops. Only occurs with a Z2 workout or during a longer warm up period. Sometimes a period of an elevated HR will follow, but more commonly HR comes back to where it was at.
Thanks
