Cardiac cycle is the term used to describe the sequence of events that occur as a heart works to pump blood through the body. The frequency of the cardiac cycle is the heart rate.\n\nEvery single 'beat' of the heart involves three major stages: atrial systole, ventricular systole and complete cardiac diastole. The term systole is synonymous with contraction of a muscle. Electrical systole is the electrical activity that stimulates the myocardium of the chambers of the heart to make them contract. This is soon followed by Mechanical systole, which is the mechanical contraction of the heart.\n\nThe term diastole is synonymous with relaxation of a muscle.\n\nThroughout the cardiac cycle, the blood pressure increases and decreases.

This isn't really a question, but a test result. What is shows is a heart that has decresed blood supply that causes changes in the EKG, which is the electrical output of your heart with exertion. \n\nThe marks on an EKG are labelled P-QRS-T. The P is the contraction of the upper chambers of your heart, the QRS is the contraction of the larger lower chambers of the heart, and the T is the relaxation phase of those lower chambers, called the ventricles. The lead numbers and letters represent directions through the heart, and which ones have changes show the cardiologist what areas have decreased blood supply. "ST" changes are the place in the PQRST the hungry muscle shows up. "Ischemia" means dimininshed blood supply.\n\nThis usually means the coronary arteries which feed the heart blood have a blockage or other restriction of flow, from clots, build up of plaque or other damage. \n\nMore tests are needed to determine what kind of problem exists. A nuclear scan would show whether muscle has already been permanently damaged  or if it is possibly reversible. The "gold standard" would be a heart catherteriztion to map the exact problem, and even fix it with a balloon or by placing a stent.\n\nA test result like this one indicates a need for more follow up and whoever has this needs to promptly follow up with a cardiologist, preferably an interventional one. It's not a time to panic but to take necessary action.\n\nHope that answers some of your question, but this should be discussed with the doctor until you are satisfied with what it means.

Depends on what grade you're in. You need something red, and some way of showing the path the blood is taking. Perhaps you should make a big cardboard or foam human body, and tape red strings all across the body in a realistic model of the human circulatory system.

Right atrium through the tricuspid valve to the right ventricle through the pulmonic valve to the pulmonary trunk to the pulmonary arteries to the capillary beds of the lungs to the pulmonary veins to the left atrium of the heart through the bicuspid valve to the left ventricle through the aortic valve to the aorta to the systemic arteries to the capillary beds of the tissues to the systemic veins to the superior and inferior venae cavae entering the right atrium of the heart.

Coronary arteries (left and right). They branch from the ascending aorta just after its start. These arteries fill with blood during diastole.\nFor more detailed information on their anatomy see:\nhttp://mywebpages.comcast.net/wnor/thoraxlesson4.htm\nhttp://www.clevelandclinic.org/heartcenter/pub/guide/disease/cad/cad_arteries.htm\nhttp://en.wikipedia.org/wiki/Coronary_artery\nhttp://www.hsforum.com/stories/storyReader$1480

It is used to view the electrical activity in your heart. It makes a map of how electricity flows through your heart.\n\nIt can show if part of your heart is getting too little blood(angina) or no blood (a heart attack or "myocardial infarction (MI)").\n\nIt can also show if one or more of the hearts chambers are enlarged or thickened.\n\nIt is also how abnormal heart rhythms (like atrial fibrillation) are diagnosed.\n\n\nFor how simple and inexpensive it is you get a tremendous amount of very important information.\n\nIt one of my favorite tests.

The Circulation of Blood\n\nThe human circulatory system is really a two-part system whose purpose is to bring oxygen-bearing blood to all the tissues of the body. When the heart contracts it pushes the blood out into two major loops or cycles. In the systemic loop, the blood circulates into the body’s systems, bringing oxygen to all its organs, structures and tissues and collecting carbon dioxide waste. In the pulmonary loop, the blood circulates to and from the lungs, to release the carbon dioxide and pick up new oxygen. The systemic cycle is controlled by the left side of the heart, the pulmonary cycle by the right side of the heart. Let’s look at what happens during each cycle:\n\nThe systemic loop begins when the oxygen-rich blood coming from the lungs enters the upper left chamber of the heart, the left atrium. As the chamber fills, it presses open the mitral valve and the blood flows down into the left ventricle. When the ventricles contract during a heartbeat, the blood on the left side is forced into the aorta. This largest artery of the body is an inch wide. The blood leaving the aorta brings oxygen to all the body’s cells through the network of ever smaller arteries and capillaries. The used blood from the body returns to the heart through the network of veins. All of the blood from the body is eventually collected into the two largest veins: the superior vena cava, which receives blood from the upper body, and the inferior vena cava, which receives blood from the lower body region. Both venae cavae empty the blood into the right atrium of the heart.\n\nFrom here the blood begins its journey through the pulmonary cycle. From the right atrium the blood descends into the right ventricle through the tricuspid valve. When the ventricle contracts, the blood is pushed into the pulmonary artery that branches into two main parts: one going to the left lung, one to the right lung. The fresh, oxygen-rich blood returns to the left atrium of the heart through the pulmonary veins.\n\nAlthough the circulatory system is made up of two cycles, both happen at the same time. The contraction of the heart muscle starts in the two atria, which push the blood into the ventricles. Then the walls of the ventricles squeeze together and force the blood out into the arteries: the aorta to the body and the pulmonary artery to the lungs. Afterwards, the heart muscle relaxes, allowing blood to flow in from the veins and fill the atria again. In healthy people the normal (resting) heart rate is about 72 beats per minute, but it can go much higher during strenuous exercise. Scientists have estimated that it takes about 30 seconds for a given portion of the blood to complete the entire cycle: from lungs to heart to body, back to the heart and out to the lungs.\n\n^_^
