[|Human|] I am a 34 year old female. I just passed out. I checked my Blood pressure about 2-3 min afterwards and it was 97/63 my heart rate was 71 and my Blood sugar was 85. What could be causing this? This is the 3rd time in a month and a half. I always get dizzy when standing. The Dr s have checked the lying, sitting, standing Blood pressure and it didn t change. They have me on a heart monitor right now for a month and I have had a Ecocardiogram. My MRI of my brain cam back good too.
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. You are having slightly lower blood pressure and normal heart rate. Normally with lower blood pressure, heart rate tend to increase. But in heart block (conduction defect) hypotension and normalized heart rate are seen. And heart block can cause sudden fainting episodes. In heart block, heart misses a beat. So blood supply to brain for that period is missed, and hence fainting episodes are seen. Holder monitoring (24 hour continuous monitoring of ECG) is must for the diagnosis of heart block. If heart block is there then you may need cardiac pacemaker. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
