Why sustained duration matters for POTS

Illustration comparing a faded brief heart-rate spike with a solid sustained plateau marked as lasting six minutes

The common POTS criterion is a heart-rate increase of at least 30 bpm within 10 minutes of standing, sustained — not a momentary spike that settles right back down.

Cardiogram now measures how long each detected rise stays elevated and reports it alongside the baseline and peak. Episode lines in the PDF export include the sustained duration, and the footer states the exact criterion used: a ≥30 bpm rise within 5 minutes, outside workouts.

That single number turns a chart your cardiologist has to interpret into a log they can act on.
