My daughter is 30 years old. 5'6" weighs approx. 130 lbs. Swims one mile three times a week, runs 4 to 6 miles every other day and does Triathlons every month or so. While at work yesterday, (physical therapist) she had been treating a patient, felt flushed and hot and light headed. She took her blood pressure and it was 145/96. She took it this morning and it was 123/82. Later this morning after doing some moving of equipment, she took it again and it was 143/94. She was diagnosed with a benign arrhythmia as a teenager and had followups with a pediatric cardiologist until 22 years old and was released. PVC's regularly but disappear over 150 beats a minute on treadmill. Don't understand the rise in blood pressure in an active, healthy 30 year old who exercises regularly and competes in races and triathlons. Any suggestions?
