What Causes Episodes Of Blurred Vision, Tachycardia And Sweaty Palms?

Today was my 4th episode, in one year, of sudden blurred vision, tachycardia, ans sweaty palms. This time the vision was only blurred in my right eye. I breath deep and try to remain calm and it usually goes away in a minute or so. Once one eye actually went partially dark. Now an hour later I am still tachy, BP is 140/98 and I just feel icky....

Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.

Regarding your concern, I would explain that it is important performing a comprehensive differential diagnosis between different possible causes that may mimic this clinical situation:

- epilepsy seizures
- cardiac arrhythmia
- transient ischemic attacks (TIA)
- panic attacks, etc. For this reason, I would recommend performing some tests:

- a resting ECG and a cardiac ultrasound
- thyroid hormone levels
- blood electrolytes
- an EEG for seizures
- a Doppler ultrasound of the carotid arteries for possible narrowing
- an ambulatory 24-48 hours ECG monitoring for possible cardiac arrhythmia. A brain MRI may be necessary.

Hope I have answered your query. Let me know if I can assist you further.
