I'm 18 years old and recently, I've started experiencing episodes of a racing, irregular heartbeat. I've had the common temporary palpitations everyone gets once in a while. However, what I've been experiencing lately is nothing like those. I've started having these periods where it's this horrible fluttering feeling in my chest that does not go away. My heart feels like it's having a hard time. I get short of breath and feel extremely weak. And honestly, it's a scary feeling.
I have listened to it with a stethoscope and the rhythm definitely seems abnormal. My heart sounds like it's beating a bit fast, but otherwise normally. Then, after around 10-15 beats, it weakens drastically (becomes soft and hard to hear), and slows significantly for 3-5 beats. It literally sounds as if my heart is struggling.
I have a physical in a few weeks and I'm going to ask for an EKG. I was just wondering if anyone has any ideas as to what it could be? Do you think it's something that needs to be checked out sooner?
