What Do Dolphins Eat. Dolphins have a varied diet in that some prefer to eat different prey whereas others are restricted to a single population. Dolphins mostly consume fish and squid. They will also chase down fish in the shallow water. This is method is called Coralling. Some other dolphin species including bottlenose dolphins have a unique method of catching small fish.
1 The R Wave is the first positive defection in the QRS Complex. 2  The S Wave is the first negative deflection that extends below the baseline in the QRS Complex that follows the R Wave. 3  The DURATION of the QRS Complex is 0.06 to 0.10 seconds in adults and 0.08 or less in children.ften the onset and end of the T Wave are difficult to determine with certainty. 1  The DURATION of the T Wave is 0.10 to 0.25 seconds or greater. 2  The AMPLITUDE of the T Wave is less than 5 mm. 3  The SHAPE of the T Wave is sharply or bluntly rounded and slightly asymmetrical.
Diagnosis is by ECG showing an undulating QRS axis, with the polarity of complexes shifting around the baseline (see Figure: Torsades de pointes ventricular tachycardia.). ECG between episodes shows a long QT interval after correction for heart rate (QTc).
