Pulse rate may be normal, but often bradycardia is present
in inferior infarction. Tachycardia is often seen with large infarctions, and may be a bad prognostic sign. Blood pressure is often elevated.
Angina is typically a substernal pressure lasting five to 15 minutes. Most of the time, it will be accompanied by radiation to the jaw, neck, shoulders, or arms. Angina is less likely to have the symptoms often associated with myocardial infarction: sweats, nausea, and shortness of breath.
