The R wave is large in lead V1. Turn the ECG upside down, and you will see ST segment elevation in V1 and a large Q wave — normal findings of a myocardial infarction. Note that the causes of the ...

This has a poor sensitivity of 27% for MI. Historically, it has been taught that detecting myocardial ischemia is not possible on an ECG in the setting of a LBBB; however, three different changes ...

Most strokes are ischemic in nature with approximately one in five being cardioembolic. Routine ECG recorded through ... such a intervals of P wave, PR, terminal velocity, P morphology, P area ...

can reduce sudden cardiac death in patients with ischemic heart disease and left ventricular dysfunction, but cumulative costs could preclude their widespread use. Microvolt T-wave alternans (MTWA ...
