Unexplained Palpitations

[LukeL]

In March I had a series of endless palpitations that started with a buzzing feeling in my chest that lasted for about 3-4 seconds. This went away and I felt fine, but I looked up causes of palpitations and within an hour got a fluttering feeling in my chest that lasted for a couple of seconds and came in a couple of runs for about 1-2 hours.

I went to the ER and they found nothing wrong with me and my EKG only showed an IRBBB and Sinus Tach.

I went to the ER two days later still afraid and they still only found IRBBB and sinus tach.

I asked to be refered to a cardiologist and had an echo done which showed no abnormalites and a perfectly normal heart.

I also had a EKG later on and it again only showed an IRBBB.

Since then I have not had the fluttering feeling but have goten very troubling symptoms. Twice I have had blury vision for a couple of seconds and have recently felt a quick lump or pulse in my neck and chest which last less then a second and comes and goes for a couple of hours.

Also during the day my chest often feels hollow or like I am getting an adreline rush that goes up into my neck.

My questions are:

1. With 3 normal EKGs and an ECHO do you think my symptoms are indicating a serious condtion (especially the fluttering)?

2. I am particualry concerned about EP condtions like Brugada and LQTS should this concern me with normal EKGs and no history of heart disease in my family? (no realitve has died from heart disease in my family)

3. I am currently on Toprol XL and Valium could this explain my periodic blured vision?

Thanks.

Luke,

Thanks for the post. Im sure these symptoms are very upsetting.

1. With 3 normal EKGs and an ECHO do you think my symptoms are indicating a serious condtion (especially the fluttering)?

If your echo is truly negative then I would probably look elsewhere for your symptoms. With your IRBB I would make sure you didnt have an ASD or PFO on the echo and would probably want to make sure a bubble study would be performed to rule these entities out.  

2. I am particualry concerned about EP condtions like Brugada and LQTS should this concern me with normal EKGs and no history of heart disease in my family? (no realitve has died from heart disease in my family)

Its unlikely without a family history. A holter monitor or event monitor would show what your heart rhythm is during the event.

3. I am currently on Toprol XL and Valium could this explain my periodic blured vision?

Most likely not unless these happen exactly at the same time of your dose administration.

good luck
