Introduction - 318 - Cardiac Rhythm.
- It is important to be aware of the settings on the equipment you are working with daily.
- Many times a calibration pulse is seen at the beginning, end or both on a cardiac tracing (it looks like a rectangle about 5 mm wide and 10 mm tall in “standard calibration”). Some units will simply print 10 mm/mV on the bottom or top of the tracing, some machines will do both. Make sure you are familiar with your equipment.
