## Description

The Essential ECG Ruler is a tool that is designed to measure the heart rate, including PR and QRS intervals, cycles, lengths, systolic length, and ST-Segment level within the paper speed range of 25mm/s and 50 mm/s. It is considered a highly versatile tool in the analysis of ECG reports, on-site myocardial infarction diagnosis as well as strip chart recordings. It can also work directly on the screen of any patient monitors and defibrillators. * Normal values for measurements such as the P wave, PR interval, QRS complex duration, and QTC interval * Heart rate measuring * Interval measurements * Visual representation of the EKG complex * ST-Segment level measurement

Review: Overpriced - In what world does a transparent piece of plastic cost 2000 rupees, it costs just 2 pounds in the uk.
Review: 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.
