I am a 25 year old female and have a history of anxiety/panic attacks but they have always been associated with PTSD, one from a traumatic experience (2008) and the other from a car accident in September 2010. For the first time I went to get help for my anxiety and was prescribed .5 mg Ativan as needed. I have only used 6 of them since because I felt better within a little over a month after the accident. Late October I admitted to the ER with tachycardia that wouldn’t go away even with an Ativan. It got so high my throat felt constricted, and all I was trying to do was sleep. I had drank a significant amount of caffeine the night before and they gave me fluids, diagnosing me with dehydration and palpitations. The doctor called my family physician and instructed that I needed to have a holter monitor because something with the EKG was very slightly off, almost nothing to worry about but he said you never mess with the heart. Instead I decided to change my diet. I haven’t drank any caffeine since October, and I drink significantly more water every day than I ever have in my life. Things were better I have been feeling so great! Until last week, when the tachycardia started again. I thought it was an anxiety attach so I took ½ a .5 mg of Ativan which helped, but the very next day it happened again. I have read that Ativan can cause rebound anxiety, so I suffered through it. Then two days later it happened again. This time I felt my heart jump or a sharp stabbing pain, and then my heart rate skyrocketed, and then went down, and back up, and down, very rapidly. I was terrified, but I was at work so I just dealt with it. It lasted a little over an hour. Another two days later, it happened again, lasting almost 2 hrs, the heart rate was about 120 BPM each episode. No other symptoms. Then again, 3 days later, I was relaxing and reading a book when my HR rose to above 150 BPM without warning, I immediately felt like my throat was constricted and my chest hurt. This time I took myself to the ER. When I got there it was down to 130 BPM, but I didn’t get to see the dr. for over an hour, watching the monitor my HR went from 120 to 80 the entire time up and down. He didn’t mention anything about that, acted as if it were normal. He told me it sounded like VT and taught me that I should hold my breath or splash my face with cold water. Suggested I definitely get a holter monitor. My apt is in a week, but I dealt with it last night and again today at work, my HR just wants to stay at 120 for some reason and I can’t focus. Today I am experiencing slightly harder than usual breathing, and have been yawning a lot. My mother told me that my grandma on her side has had tachycardia issues, and my aunt on my dad’s side had to have surgery for it. I’m just scared to deal with this for the next week every day. If it occurs every day is it anxiety or a heart issue? I can’t figure it out. I have zero other symptoms besides my heart…and no current stressors. I am a mom but I have been a mom for 6 years and it’s not bothered me before. I’m worried to be alone with them because I don’t want it to happen again and scare them. I can handle the 120 bpm, while it distracts me and scares me, it’s far less scary than 150. It lasts for hours. Does anxiety last that long? I’m afraid my family physician won’t be of any help, and what if the holter monitor doesn’t catch it happening? I’m just confused and worried.
