what is "ST Segment"?
99099
The ST segment refers to a portion of the electrocardiogram (ECG)waveform.\n\nThis portion basically represents electrical waves coming from your heart as heart cells recharge themselves in between heart beats.\nDoctors look at this portion to access the health of the cardiiac muscle. Essentially they look for either ST segment elevation or ST segment depression.\n\nST elevation: implies an ongoing acute myocardial infarct (fancy lingo for heart attack where heart cells are dying)\nST depression: implies ongoing ischaemia (fancy lingo for saying too little blood going to the heart without cells actually dying)\n\nThe ECG composes of many other components other that the ST segment and all these add to the final picture and a fuller interpretation of the health of a patient's heart.

Echinoderms are not segmented, as others have already said.\nAnd the word "echinodermarta" literally means "spiny skin", and they do have skeletal "plates" on their outsides, though in some echinoderms (like sea cucumbers) these are kind of soft.

The way to figure this out is, \n\nS=segment length of arc \nA=angle subtended by arc\nR is radius of circle \n\nS/A=2*pi*R/(2*pi),\n\nso S=RA\n\nthen differentiate with respect to time t, \n\nand dS/dt=R*dA/dt,\nand dA/dt=w, the angular speed\n\ndS/dt=T, tangential velocity\n\nso T=R*w

That would be called a secant. By definition,\n\ntanget - making contact at a single point; touching but not intersecting\n\nradius - a line segment that joins the center of a circle with a point on its circumference\n\nA secant is a line that intersects the circle in exactly two points

"The normal electrical conduction in the heart allows the impulse that is generated by the sinoatrial node (SA node) of the heart to be propagated to (and stimulate) the myocardium (muscle of the heart). When the myocardium is stimulated, it contracts. It is the ordered stimulation of the myocardium that allows efficient contraction of the heart, thereby allowing blood to be pumped to the body.\n\nUnder normal conditions, electrical activity is spontaneously generated by the SA node. This electrical impulse is propagated throughout the right and left atria, stimulating the myocardium of the atria to contract. The conduction of the electrical impulse throughout the atria is seen on the ECG as the P wave."\n\n"An electrocardiogram (ECG or EKG, abbreviated from the German Elektrokardiogramm) is a graphic produced by an electrocardiograph, which records the electrical voltage in the heart in the form of a continuous strip graph."\n\n"An ECG measures the electrical potential between leads placed on various points of the body."\n\n"The leads measure the average electrical activity generated by the summation of the action potentials of the heart at a particular moment in time."

this is actualy s = ut + 1/2 a (sq of t)\nIts an equation of motion. n of gr8 use in physics. \nHere, s stands for displacement of an object or body, u for its initial speed, t for time taken.

The area of the segment is given by\n\nA = r^2[theta - sin(theta)]/2\n\nSo we need theta, which is the angle that contains the chord, and the radius of the circle.\n\nThe radius of the circle is given by\n\nr = (c^2 + 4h^2)/(8h)\n= (20^2 + 4(6)^2)/(8*6)\n= (400 + 144)/48\n= 11.3 m\n\ntheta is given by\n\ntheta = 2 arcsin(c/[2r])\n= 2 arcsin(20/[2(11.3)])\n= 2.17 radians\n\nSo\n\nA = r^2[theta - sin(theta)]/2\n= (11.3)^2[2.17 - sin(2.17)]/2\n= 85.92 m^2
