Blood Test after a 24 hour heart monitor?

[gemma1304]

I have recently felt my heart beating very fast / irregularly and was concerned. I went to the doctor who sent me for a 24 heart monitor, which I wore but didn't experience these irregularities during the 24 hours. Two weeks later I called for the results and was told I need a blood test before I go to get these results. Why is this? Thanks.

I am having the same experience right now!  I'd love to know what your tests ended up showing.  I received a call about 30 minutes after I dropped off the monitor which to me indicates something is up with my tests. I had an abnormal EKG before an outpatient procedure a year ago and they told me to consult with my Dr.  The EKG they did the day they gave me the monitor was normal.  All that he listened to seemed normal but he wanted to be sure so sent me home with the monitor, now I need blood tests before I can get the results.

I have no idea. Unless they want to test for anemia or low potassium or such things that may trigger some arrhythmias. I've never been told I had to have a blood test before getting results from a monitor. Sounds like someone was just being weird. And the monitor won't be much help if you didn't have any episodes while wearing it. Don't get discouraged. If the tachy only happens occasionally, not every day, you may want to ask about wearing an event monitor instead.
