Palpitations? Over the last couple of weeks I've been having episodes where my heart has been racing. My heart rate jumps to between 110-170 beats/min Its not painful but concerning. It comes out of nowhere whether I'm exerting myself or not. It feels like an adrenaline rush.... I've spent 2 days in maternity triage and no reason has bn found. Still to get further investigations. Has anyone else experienced anything like this?
