Tap a lead on the 12-lead to see its own measurements
Before
Tapping a lead zoomed into its wave with one number per wave, the same all-leads figure under every lead, and nothing to show where it came from.
After
The view shows the lead's own measurements: QRS shape, R and S heights, the ST at the J point with that lead's STEMI threshold, and its T and P, with calipers on the wave marking where each number comes from.
