Hello, I am a 22 year old female and have been having palpitations/arrythmias for the past 4 years, not frequently. however, in the past 4 months i had a terrible palpitation that made me feel extremely faint. then a week ago i had left arm tingles/pain near my hand and a minute or so following that i had a heart palpitation... then a fast heart beat for about 12 hours and felt fine. then 4 days later i had another episode and have had a fast irregular heart beat, high bp for me 140/80 just relaxing and tingling, numbness sensations in my hands and feet that come and go for the past 5 days. I have been stressed with biochem research and a new hostessing job, fathers aortic occlusion surgery, and my boyfriends depression (thats bounced back to normal)..... however i did take plan B about 2 weeks ago and had a light period after 2 days of taking it which was blackish in color. i have a cardiologist appt in 2 weeks and a gp appt in a couple days. i went to the ER because my symptoms were lasting too long. the ekg and bloodwork were all normal.
