Tests: Ekg and blood samples are needed. Most homes don't have this capability so you'll probably need to consult your doctor.

Classically,: Angina pectoris =substernal pressure, pain with radiation to the neck or left or right arm and shoulder.

A feeling of impending doom, pallor, sweating suggest a bad day! panic attacks can approximate.
