Scientists are studying bats and their use of echolocation to learn more about how bats process information to understand and adapt to the world around them. Echoes of hunting They detect and catch their targets through echolocation, or biosonar, the animal equivalent--and precursor--to man-made sonars. How to see what whales hear: biomedical imaging reveals new insights into marine mammal ears
The faster repolarization of the cardiac action potential causes the tenting of the T waves, and the inactivation of sodium channels causes a sluggish conduction of the electrical wave around the heart, which leads to smaller P waves and widening of the QRS complex.
Causes of T-Wave Abnormality on an EKG. Abnormal T-Waves on an EKG aren't necessarily an indicator of a problem. However, they could cause your doctor to want to do further testing. 1  slide 1 of 5. The heart has its independent electrical systemâ a network of nerves located throughout all its chambers, which mediate electrical impulses that enable chambers to contract in a synchronized rhythm and sequence. 2  slide 2 of 5.
