When teaching ECG, I always try to make the ECG interpretation have some practical context for the student.  Why study squiggly lines, if they don't mean something to our care of our patients?  Even putting a simple scenario (actual or invented) with an ECG can make it more relevant for your students.  A series of ECGs taken as the patient undergoes changes, is especially helpful.

Here, we present six ECGs generously donated to the ECG Guru by Jenda Enis Štros.  They follow a man through an acute anterior wall M.I., from pre-hospital treatment, the Emergency Department, Cath Lab, thrombosis of his stent, repair, and recovery.  In the future, we will be adding other series of ECGs, labelled "Series" to help you find them on the navigation pane.
