My pulse under my throat, I have copd how do I know if this is congestion or heart issue I am female 54 yrs old

No need to post twice, I have Already answered your first post.

It could be gas or indigestion. It could be that your LDL cholesterol is too high. It could be something you are eating such as milk which can cause mucus plugs to form in your bronchial passage way which subsequently can interfere with your breathing and heart. You also must know that copd also can affect the heart in an indirect way. Angina suggests that your heart is not getting enough oxygenated blood, and when this happens it can cause you to experience chest tightness and even pain. Please make an appointment with your doctor for an evaluation before you have a heart attack okay?
