Mary Hoeller – December 24, 2025

The BEST EKG Ruler (I’ve tried them all)
Sturdy reference showing normal limits for all parts of the EKG cycle that I use everyday as an ER doc (the mV scale is THE BEST). Just throw it on top and go. I only wish they made a smaller version WITHOUT the extraneous scales for non-standard speeds and amplitudes because it’s a little too large to carry around easily.
