My heart is beating fast. I feel dizzy, and my vision goes blurry for a few seconds. I also feel short of breath briefly. What could be causing this?
The symptoms you are describing, rapid heartbeat, dizziness, brief blurred vision, and shortness of breath, may indicate a potentially serious heart or neurological issue, such as an abnormal heart rhythm, low blood pressure, or other cardiovascular or neurological conditions. You must seek immediate medical attention by contacting a doctor or going to an emergency room, so that the cause can be properly evaluated and treated.
