Add right-sided leads V3R and V4R. ST elevation of ≥0.5 mm in V4R has a sensitivity of 90% and specificity of 95% for acute right ventricular infarction—a finding that changes management (avoid nitrates, maintain preload).
To fully grasp the depth of this phrase, one must deconstruct it into three critical components: the anatomy of the inferior wall, the electrocardiographic mimics that plague its interpretation, and the clinical imperative to move beyond the ECG alone. cannot rule out inferior infarct
Here is the plain-English translation of what that phrase actually means, why computers write it, and what you need to do next. Add right-sided leads V3R and V4R
Do not assume you have had a "silent heart attack." There is a very high chance this is a "false positive"—a computer error. Here is the plain-English translation of what that
An elderly diabetic with chest pressure radiating to the jaw, diaphoresis, and this ECG finding is having an infarct until proven otherwise. A healthy 25-year-old with pleuritic chest pain and the same ECG tracing is highly unlikely to have coronary disease.
The primary cause of an inferior infarct is a blockage in one of the coronary arteries, usually the RCA. This blockage can be due to a blood clot (thrombus) or a buildup of plaque (atherosclerosis). Risk factors for developing an inferior infarct include:
