Recently I just learned about brugada syndrome which is an abnormality in the heart that causes it to beat irregularly. This can lead to sudden death most likely while at rest or while asleep. With this being said it makes me question whether or not I have this or if it's just panic attacks. The reason I question this is because I get more than one so called "panic attack". Sometimes they will come out of nowhere and I won't be thinking about anything stressful. My heart just feels like it's beating out of rythmn and feels like it's going to come through my chest. My chest gets tight and it aches. Other times while I'm having an attack I get light headed, panicky, hot, negative thoughts, fear of dying, and the feeling I'm going to pass out. Along with this my heart does get Racey but nothing like it does when it feels like it's beating out of rythmn. Anyone experience this? It's like having more than one type of panic attack or maybe it's a health issue I should be concerned about? Any help/advice is appreciated. Thanks in advance!
