In `@packages/core/src/RenderingEngine/GenericViewport/ECG/ECGResolvedView.ts`:
- Around line 192-205: Update the channel-layout construction in ECGResolvedView
to build layouts from each trace region rather than using the filtered
visibleChannels position as the lead index. Preserve the original lead index,
bounds.minX/maxX/minY/maxY, and timeWindow, then make canvasToWorld and
worldToCanvas use that region-specific geometry for selection and placement.
In `@packages/core/src/utilities/ECGUtilities.ts`:
- Around line 417-421: Update the trace-region sample-bound calculation in
ECGUtilities to offset and clamp minX/maxX against the active
startIndex–endIndex window before deriving segStartIndex and segEndIndex.
Preserve the existing channel.data bounds while ensuring regions scroll with the
active time window.

In `@packages/core/src/RenderingEngine/GenericViewport/ECG/ECGResolvedView.ts`:
- Line 104: Update canvasToWorld and worldToCanvas to preserve the selected ECG
trace-region identity rather than storing only channelLayout.leadIndex; encode
and resolve the exact region, including duplicate leads such as rhythm lead II.
Use each region’s bounds and timeWindow when converting x coordinates in both
directions so annotations map to the correct samples, and remove the unrelated
positional fallback (including the ?? 0 fallback on channelLayout.leadIndex).
In `@packages/core/src/RenderingEngine/GenericViewport/ECG/ECGViewport.ts`:
- Around line 352-358: Update the view-reference validation around
getFrameOfReferenceUID so references without referencedImageId are accepted only
when their FrameOfReferenceUID matches this viewport’s scoped ECG identifier. Do
not let a missing current image or absent referencedImageId fall through to
unconditional true; preserve the existing hasImageId check for image-specific
references.
- Line 405: Update ecgCalibrationProvider to return an IImageCalibration object
that includes type set to CalibrationTypes.REGION alongside
sequenceOfUltrasoundRegions, and remove the unsafe cast at the calibration
assignment in ECGViewport.

- Around line 144-147: Update ECG layout resolution so each layout preserves its
region index and timeWindow, and encode region identity in the world z value to
distinguish duplicate leads. Revise worldToCanvas and canvasToWorld to select by
region bounds and map x using that region’s timeWindow, avoiding positional
fallback to unrelated layouts. Reuse the shared TraceRegion type in
computeECGRenderMetrics and drawECGTraces so timeWindow is not lost.

In `@packages/core/examples/ecg/index.ts`:
- Around line 256-257: After the local waveform replacement in the
setDisplaySets flow, rebuild the trace checkbox controls from the newly loaded
channel metadata and reset allVisible to its default state. Update the existing
control-construction logic rather than only changing the display set, ensuring
labels and per-lead toggles match the uploaded waveform.
In `@packages/core/src/utilities/ECGUtilities.ts`:
- Around line 371-374: Update computeECGRenderMetrics so channelScale uses the
rendered lead-slot count from each region’s leadIndex span, matching
drawECGTraces rather than counting each region once; preserve
visibleChannels.length when regions are absent, and add a regression test
covering a multi-lead region to verify traces remain within their assigned
slots.
- Around line 511-512: Update the empty-lead fallback in drawECGTraces to use
the current region index rather than always defaulting to lead 0, and apply the
same [regionIndex] fallback in ECGResolvedView.getChannelLayouts so rendering
and coordinate conversion select the same lead.
In `@packages/tools/src/tools/WaveformRegionOverlayTool.ts`:
- Around line 419-420: Update the rendering flow around _renderStackedChannels
so showLabels only controls label rendering, not box rendering. Render boxes
independently for each active channel row using styles.showBoxes and the
existing drawRectByCoordinates path, including when styles.showLabels is false,
while preserving the current label behavior.
