A post from March 15 on the A & S Research website simply states, âToday is a sad day to report the passing of Dr. Roger K. Leir, we have lost a great family man, podiatrist and devoted ufologist. He will be greatly missed by all.â.
On the ECG, failure to capture is identified by the presence of pacing spikes without associated myocardial depolarization. Causes include pacing lead problems, battery or component failure, low pacing voltage or elevated myocardial pacing thresholds, and exit block.
Eye floaters result when something besides light from the environment stimulates the retina, which is the light-sensing structure at the back of the eye. This stimulation causes the retina to send a signal to the brain. The brain may interpret the signal as an apparent object floating in the field of vision (floater) or as a simple, sudden flash of light that can look like lightning, spots, or stars (photopsia). Photopsias can occur when the eyes are rubbed.
