68 year old male. Have had watery diarrhea for 6 days, but less volume today, so may be ending. However, have experienced odd feeling in chest for several days, worse today (anxious or pressure). Checked pulse, and am getting variable skipped beat every 4th to 8 beats, sometimes further apart. Concerned about this and odd feeling in chest. Am in good health, run 12 to 16 miles a week, exercise regularly.
