I was just laying in bed nearly asleep and then BAM I get hit with a very abrupt heart palpitation, I was told that you get palpitations caused by your anxiety, but these are really scary, it felt like my heart stopped for a quick second then it just started racing really fast and hard, I immediately went into panic mode. Why do you get palpitations? Should I go see a cardiologist, I'm so scared. The reason I have anxiety and always fear my heart is because my 4 year old just had open heart surgery 2 years ago and my Dad also passed away from heart complications. Please help. Anything helps!!!
