My Ophthalmologist used Neosynephrine to dilate my eyes. I experienced irregular rapid heartbeat which continued for hours. After 8 hours, I then went to the hospital emergency room and was released about 3 hours later. I left with a slight irregular heart beat after taking beta blockers while being monitored.
