Why do I feel light headed with decrease in BP?
Patient: 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? Doctor: Hello!Welcome and thank you for asking on HCM!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, Dr. Iliri
