[|Human|] I have had 2 heart ablations within the past 2 months...get lightheaded 2-3 times a day, usually with activity..blood pressure will go high and drop 20-30 points when feel lightheaded..usually have the tunnel vision almost syncope but can sit and work through it.. What can be causing this. I already see a cardiologist and a neurologist who has not ordered any other tests yet. Why is this happening more now?
[|AI|]  Hello! Welcome and thank you for asking on Chat Doctor! Regarding your concern, I would explain that your symptoms could be related to orthostatic hypotension. A cardiac arrhythmia can not be excluded either. I recommend performing these tests: - a Head up Tilt test to exclude possible orthostatic intolerance- an ambulatory 24-48 hours ECG monitoring to examine your heart rhythm trends during the day- a cardiac ultrasound to examine your cardiac structure and function-blood lab tests (complete blood count, blood electrolytes, kidney and liver function tests, blood fasting glucose). You should discuss with your doctor on the above-mentioned tests. Hope you will find this answer helpful! Kind regards,
