my heart suddenly started beating irregular and i was short of breath and my arms, legs, and head began to tingle as if they were asleep.then after a few minutes it went away but left me cold and sleepy and still lightheaded, this has happened in lesser extremes in the past and i was told it was a panic attack ... does this sound like heart related issues or a panic attack? I literally thought i was gonna die!! How do i decipher the difference between the two? I already take toprol XL for palpitations... I don't know if i should be headed to the hospital, or taking some anxiety meds......any help is appreciated
