Also, if a patient has persistent angina and a non-diagnostic ECG, record leads V7-V9. ST-segment elevation in those leads may be the only ECG indicator of ischemia (usually LCx ischemia). -Large and/or wide R wave in leads V1 or V2 supports the dg of posterior infarction but is only seen in ~50% of the cases.

Cardiac Rate, Cardiac Rhythm, Axis Deviation, Blocks, and Ischemia – This material makes up 95% of all cardiac problems. We will not be looking at bacterial or viral infections of the heart. 12 Lead EKG. The standard EKG is 12 leads. A lead refers to a view of the heart. There are 12 views of the heart in a normal EKG. EKG comes from German.

Note- one normal ECG does not exclude cardiac ischemia. Leads & relationship to heart Septum = V1-V2 Anterior wall = V3-V4 Lateral wall = V5, V6, I, aVL Inferior wall = II, III, aVF. 1. Look for . Q waves. Pathological Q waves indicates an AMI (new or old). Any Q wave in V1-V3 0.03 seconds or wider (0.03 seconds is ¾ width of one little square)

Severe myocardial ischemia and its complications: a “heart attack.” Cardiac arrest: ventricular fibrillation or asystole. Myocardial Infarction. LOCATION: ALMOST ALWAYS LEFT VENTRICLE. Anterior wall: left anterior descending artery distribution. Lateral wall: circumflex artery distribution. Posterior wall: right coronary distribution.

Posterolateral (LCX) ST depression but upright T waves in V1-V3 (diff dx: ant. ischemia or posterolateral STEMI) later: increased R/S ratio in V1-V2. frequently accompanied by small Q waves or T-wave inversion in inferior or lateral leads

You’d think that this would mean lateral ischemia, but no – it’s a reflection, bouncing electrically across the heart from the inferior injury, showing up in reverse. Yup, it’s confusing. The trick is to remember that when assessing EKG changes, ST elevations always come first – ahead of anything else on an EKG.
