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.
5 Causes Of T-Wave Abnormality. T wave is basically the diagrammatically representation of ventricular polarization called electrocardiography. The structure of a T wave is like slight inverted upward stroke that follow a peak generated by R and S waves. One heart beat is represented in form of Q, R, S and T wave. The abnormality in T waves may be indicated by longer, flatter or higher peaks in the diagram. The measurement of heart beat in such a way makes it possible to diagnose heart related problems easily. If you are suffering from any heart related disease, the electrocardiogram will show an abnormality in the T wave. In this write up we will discuss various causes of abnormality in T wave measurement.
