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.
All that produces tall, peaked T waves is not necessarily hyperkalemia! Instead, the finding of Twave peaking should prompt one to consider a differential diagnosis of 3 possible causes â with the clinical situation (as well as specific ECG features) providing KEY clues as to which of the 3 is likely to be present. However, the most remarkable finding are the very tall, peaked T waves with narrow base (Eiffel Tower effect) in several precordial leads (Figure 2). 2  This strongly suggests Hyperkalemia.
