The minute this medical student saw the first ECG, he knew the diagnosis without any further information. Reading ECGs is hard, but can be done with commitment to learning, which comes from an awareness of its importance. You need to be interested and understand the value of the ECG. She had this ECG recorded: ECG 1: QTc is 484.

The full differential diagnosis of sinus tachycardia in isolation is extensive ranging from benign etiologies such as anxiety to severely life threatening etiologies such as sepsis. Glucose POC ECG: Is this actually sinus tachycardia? Looking at the initial or even repeating the ECG will be helpful here. Do they have edema?

Some total LAD occlusion manifest on the ECG similarly to some left main occlusions. Depending on where the STE vector of the LM occlusion shows up on the ECG, there may be either STE, or STD, or neither in aVR, and lead aVR will not be the important part of the ECG interpretation in these cases.

An immediate 12-lead EKG was obtained: There is ST elevation in leads aVR and V1, with marked ST depression in I, II, III, aVF, V3-V6. DISCUSSION: The 12-lead EKG EMS initially obtained for this patient showed severe ischemia, with profound "infero-lateral" ST depression and reciprocal ST elevation in lead aVR. What should be done?

What is your ECG interpretation and what would you do next? This ECG shows a normal sinus rhythm with a normal conduction pattern (normal PR, normal QRS, and normal QTc), normal axis, late R wave progression (and misplaced V2), normal voltages, ST-elevation in aVR and global ST-depressions. BP was 110 and oxygen saturation was normal.
