For a strip with a PVC or V-TACH RUN, consider the pattern ___________________ -
✔✔irregular
Define rhythmicity - ________ __________________ - ✔✔heart rhythm
Define _________________- shape and size of specific complex or waveform - ✔✔morphology
Minimum length before interruption of a tracing is ___________ seconds - ✔✔6
