i recently wore a heart holter for 24 hours. the result said i had premature arteril contractions. my heart rate went down below 41 beats especially in the mornings and had a average beat of 69. i have sudden dizziness and fatigue,feelings of suddenly passing out but i catch myself, and panic or anxiety attacks. what could be going on with me sometimes i feel a small achy pain in my chest but it goes away and it also feels tight sometimes. my doctor is sending me for a stress test is this going to help or is there some other kind of test i need. help i've got to find out whats going on with me.
