Overview
The EKG in patients with unstable angina can be variable. In some cases, no changes on EKG will be appreciated. In other cases, a resting EKG may show flipped or inverted T waves, ST segment depression, or non-specific ST-T changes. It is the first line of assessment in any patient suspected of having unstable angina.
Electrocardiogram in Unstable angina / NSTEMI
The resting electrocardiogram in the patient with unstable angina / non-ST elevation MI may show any of the following:
- No changes
- Non specific ST / T wave changes
- Flipped or inverted T waves
- ST depression as shown below. ST depression carries the poorest prognosis. Greater magnitudes of downsloping ST depression are associated with a poorer prognosis.
EKG Examples
Shown below is an EKG from a patient with unstable angina. ST depression in V2, V3,V4 and V6 can be noted.
