Hi, I have been experiencing wild palpitations on and off for 4 years and recently had a fast pounding heart which has been very frightening my last one was last night, I slept for around 3. Hours then could not sleep, made a decaf coffee, cheese scone & 2 paracetamol as I had a fuzzy headache. My pulse went to 120 for approx 1. Hour. Finding this site helped me to calm down and I'm wondering if anxiety and stress can be my key factor. I have many stressful situations going on in my life at the moment even though I am happy.
