A warm welcome to HealingWell,
You are in the same boat with so many others re the fear that anxiety can harm you. When the heart begins to beat quickly and people experience "palpitations", they sometimes feel a heart attack is occurring. In the first place, the heart can beat quickly and continuously for a long period of time without causing any damage. Although heart palpitations seem to occur in the left side of the chest, there are many differences between anxiety attacks and a real heart attack. During a real heart attack, the primary symptom is a crushing sensation inside the chest and a pain that is continuous. During a panic attack, the attention is focused on the quick and rapid beating of the heart itself. ("I can hear my heart beating even in my ears!") People having panic attacks are NOT experiencing heart problems. A real heart attack produces crushing internal pain that doubles people up and drops them to the floor. They do not hear their heart beating nor do they care. The intense, crushing pain is the only thing they can pay attention too.
If you continue to have concerns re your heart, please do follow up with your Doctor.
Kindly,
Kitt
