ST elevation acute inferior MI (And reciprocal ST depression)
(Click
for 12 leads ECG) | Comment | . | II
| III | aVF | . | I | aVL | . | V1 | V2 | V3 | V4 | . | V6 | V3R |
(Case 4) | ST elevation in inferior leads is mild. The reciprocal ST depression in V1-V3 is more prominent. This may lead to a misdiagnosis of anterior ischemia or non Q wave MI (non ST elevation MI) | . |  |  |  | . |  |  | . |  |  |  |  | . |  | . |
(Case 3) | Straight ST or mild coving ST (even with minimal ST elevation or without ST elevation) is also diagnostic for current of injury. Reciprocal ST depression in V1-V3 confirms the diagnosis of inferior MI. | . |  |  |  | . |  |  | . |  |  |  |  | . |  | . |
(Case 1) | ST elevation in inferior leads is mild. The ST segment is less concave. There is prolong QT interval. Reciprocal ST depression in I, aVL, V1-V3 confirms the diagnosis of inferior MI | . |  |  |  | . |  |  | . |  |  |  |  | . |  | . |
(Case 2) |
A more typical case of acute inferior MI with easily recognized ST elevation and hyper acute T wave in inferior leads and reciprocal ST depression in I, aVL, V1-V2. | . |  |  |  | . |  |  | . |  |  |  |  | . |  | . |
(Case 5) | Right side chest leads should be done at the same time of initial ECG. It should be within 6 hours after the onset of chest pain. ST elevation in V3R and V4R of >1 mm support the diagnosis of RV MI with inferior MI. | . |  |  |  | . |  |  | . |  |  |  |  | . |  |
