Measure EKG intervals, heart rates, QRS complex segments, and identify ST segment elevations or depressions with this Rapid ID from MDpocket. Quickly identify EKG abnormalities with the clear vision window (ST segment elevations/depressions) that can help you find ischemia or an infarction. Measure heart rates down to 20 beats/minute and heart rate pauses to 3 seconds on full 12-lead EKGs or rhythm strips. Standard reference ranges are provided for the P Wave, PR Interval, QTC Interval, and QRS Complex to compare your tracing. A sample EKG complex with each area that can be measured is located on the front of this card to help you find the appropriate interval. Carry this card behind your hospital or ID badge for rapid referencing and daily use.
