An electrocardiogram (ECG or EKG) is a method to graphically display the electric current generated by the heart muscle during a heartbeat. This SIMTICS module teaches you how to prepare for, record and interpret a 12-lead ECG. The interactive simulator lets you learn and practice how to record an electrocardiogram, and how to interpret the heart rate and rhythms for common pathologies. Online simulations offer a safe practice environment and also enable you to try out procedures that you might not otherwise experience. This module is ideal if you are studying for the American Registry for Diagnostic Medical Sonography (ARDMS) registry exams.
