Hello, recently I've been having heart palpitations - flipping, skipping and racing. I have had like 10 ecg's, full blood tests, x-ray.. It was all clean so they blame it on anxiety..but sometimes I get them all of a sudden,no reason behind them.. I usually get lightheaded right before that, or extremely weak. I have had all other symptoms like chest pain, headaches, irritated eyes, weakness,nausea... Is it really anxiety?
