Hello, I am 36 yrs old, 5'5" and 130 lbs.  I feel like my heart is skipping a beat, then beats hard, then feels normal.  It happens when I hold my breath for a moment or when I take a deep breath. This is happening about every 3 minutes for the past 5 days.  I wake up from sleeping due to it also.  I am am overall healthy woman in good shape.  Only medical history is i am Factor V positive with history of superficial clots in arms 4 years ago.  Is this something I should be concerned about?  Thanks!

Summarized question: What are the symptoms of Factor V positive?
