I’m a 20 year old (otherwise healthy) girl. My episodes have been increasing of what I believe to be SVT. I’ll feel it coming on and a lot of times it happens when I first wake up in the morning. My heart will start to race and it’s accompanied by nausea, sweating, chest pain, chest and neck tightness, lightheadedness/dizziness and uncontrollable shaking/trembling. I’ve been to the ER several times and had a series of tests but none of the tests have been able to catch it. My bpm usually lowers by the time they get the ekg on me. The highest they’ve gotten my pulse at the ER is about 130. I’ve had 24 hr Holter monitors but of course I didn’t have an episode while it was on. I’m extremely frustrated and hopeless because many doctors have blown me off and told me it’s anxiety, although these episodes happen when I’m completely calm, and have even woken me up from sleep. Anxiety meds like Ativan calm me down but don’t stop the episodes. They have been increasing a lot lately too. They used to just happen every few months to every few weeks to pretty much every day now. I’m scared that each time it happens my heart won’t be able to take it and I’ll die. I’m living in extreme misery and fear every single day and it has completely taken over my life. Does anyone have any advice on how to stop the attacks once they start and anything that’s worked for them to control it? I’m so young and I live in fear of dying every moment of the day.
