<s>[INST] I have long qt syndrome, and got an icd 4 years ago.  I have done great and am a runner now.  I have recently been having high blood pressure and a high resting heart rate of 100.  I do run every day and eat healthy, no smoking or alcohol.  I have had headaches and swollen feet also. [/INST] Hello! Welcome to Chat Doctor! Considering your complaints and your past medical history, I would recommend performing some tests to investigate for the possible causes of your symptoms: - a resting ECG and cardiac ultrasound to examine your heart function and structure- a chest X-ray study-complete blood count for anemia-fasting glucose for diabetes-kidney and liver function tests for possible dysfunction- thyroid hormone levels for possible dysfunction which could lead to high blood pressure and heart rate-blood electrolytes- inflammation tests (PCR, sedimentation rate) for possible inflammation. You should discuss with your doctor on the above issues. You may need to start antihypertensive therapy. Treatment of the underlying cause (if detected) would also improve the situation. Hope to have been helpful! Kind regards,  </s>
