Hi, I recently keep getting a racing heart along with a "anxious" feeling or adrenaline rush (although I have nothing to be anxious about). Occasionally, it will cause a bit of a head rush and make me slightly out of breath. It generally happens in the evening, when I'm resting and only last a few seconds, but will come and go throughout the evening. I have also noticed i have palputations (like my heart beat skips a beat). I'm in my late 20s, don't drink or smoke and generally healthy. My mother suffers with palputations and is on medication. Is this something that will pass or triggered by anything please?
