###Human: Why am I getting palpitations frequently? ###Assistant: Hi. Yes, I would say palpitations with light-headedness likely indicates some serious kind of arrhythmia. You are lucky that in 30 years, you did not pass out but there is a risk that this kind of arrhythmia can be fatal. I would suggest visiting cardiologist. Repeat EKG and echocardiogram, you might need a Holter monitoring for 24 hours and ultimately might need medication or pacemaker depending on severity and type of arrhythmias. I am suspecting it to be SVT or VT runs.
