Riding roller coasters may actually be 'death-defying' for people with heart disease
...ng episode of atrial fibrillation, a rapid chaotic electrical
activity in the upper chambers of the heart. "After the ride stopped, nearly half of the participants had irregular heartbeats or significant sinus arrhythmia, even though their heartbeat rates had returned to normal and were inside the range of a no...
Connective tissue cells from lungs fused with heart muscle to form biological pacemaker
...ther gene, If, which produces proteins involved in electrical
signaling, called pacemaker channels. Such channels are protein structures that permit electrical
signals, the ions, to pass in and out of cells. Within three minutes of fusion, the cells showed sig...

Squinting while staring at a computer monitor can cause painful dry eye
...d to an electromyogram, a machine that records the electrical
activity of muscles. In this case, the researchers wanted to record the action of the orbicularis oculi muscle, which encircles the eye socket and allows the eye to both blink and squint. The electromyogram measured the different degrees of squint. ...
World first trial to test human implant of HeartPOD

Inflammation linked to chronic pain: Study
...ainful event, receptors in the injury site send an electrical
impulse up the spine and to the brain. The signal triggers receptors called glutamate AMPA and kainate, which flare up initially but do not directly alter the physiology of the cells. When the painful event also triggers inflammation, the nerves send...
