My experience today

When I am having irregular rhythms I sometimes have wide swings in my heart rate so I am tachyBrady at times. I also get wide swings in my blood pressure. I feel bad if I have a pulse pressure of 25 or less and it also effects me when my pulse pressure is far apart, ie: 120/45.  Today I started feeling dizzy and strange with shortness of breath. I monitored and I was irregular rhythm with 126/103 with HR of 64.  This lasted for just under a half hour.  Afterwards I was worn out.  Is this something I should be concerned about?  By the time I could get to the doctor it would be over and they wouldn't be able to catch it.  It is quite frustrating. The last event monitor I had didn't show anything though I wore it for 21 days. Took it off and 2 hrs. Later my heart rate went into the 30s.  My EP just says quit monitoring and don't worry a bout it unless I pass out.  Kinda late then To worry I would think.  Maybe I need Dr. House.
