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.

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.
T wave: The T wave represents the repolarization of the ventricles. It is generally upright in all leads except aVR and lead V1. Inverted T waves can be a sign of myocardial ischemia, LVH, high intracranial pressure, or metabolic abnormalities. Peaked T waves can be a sign of hyperkalemia or very early myocardial infarction. 160 ms
