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.
of His, which conducts the signal through the interventricular septum towards the apex of the heart. Soon after entering the interventricular septum the AV bundle bifurcates into two separate branches. The conduction of the electrical signal through the interventricular septum, coupled with the slow conduction velocity of the AV node, causes a delay from when action potentials form in atrial myocardium and when they form in the ventricular myocardium (and subsequently in when the two sets of chambers contract) called the atrioventricular delay. This delay ensures that atrial systole is complete at the onset of ventricular systole. Once the signal reaches the apex of the heart it is conducted up the lateral walls of the ventricle through branched tracts of pacemaker cells called Purkinje fibers, which distribute the electrical signal to the ventricular myocardium. Electrical changes occurring during the cardiac cycle can be monitored from the surface of the body in a recording called an electrocardiogram (ECG, or EKG). A normal
