This badge card is a 12 lead STEMI reference tool. It shows the standard 12 lead layout and the associated “adjacent” leads relative to the location in the heart. On the back there is also a chart of ST changes and their association to particular coronary vessels. The tool also includes a ruler for measuring ST elevation and depression. <br> <br> This badge card comes from a series of cards that puts hard to memorize information at your fingertips. It has a standard slot pre-punched that will work with badge clips and badge reels. <br> <br> This card also comes in both vertical or horizontal format. Purchase whichever version works best for you. <br> <br> Card made of durable plastic, is waterproof, and is about half the thickness of a credit card so it wont weigh down your badge reel or feel bulky. <br> <br> Double sided and uses the entire printable area to maximize the total information. Same as a standard badge ID card (or credit card size; 3 3/8" by 2 1/8").
