To ensure an adequate blood supply around your body, the four chambers of your heart have to pump regularly and in the right sequence. Sudden cardiac arrest is the sudden loss of heart function, breathing and consciousness. It’s usually due to a problem with the heart’s electrical system. If not treated immediately, it results in sudden cardiac death.
Your heart is slightly on the left side of your body. The left lung is slightly smaller to make room for the heart in your left chest. We can see the Germanic influences in the word heart by looking at the Old Saxon herta and the German herz. If we go back even further, however, we see the word also has ties to the Greek kardia, which makes sense when we consider that the prefix cardio refers to the heart. For example, a cardio workout is one that gets the heart pumping harder, and a cardiologist is a doctor of the heart. If someone asks that you “have a heart,” however, they are appealing to your sense of generosity not to the blood-pumping organ.
Heart disease symptoms depend on the type of heart disease. The heart here resembles a pine cone (held “upside down”, the point facing upward), in accord with medieval anatomical descriptions. Moreover, the French title of the manuscript that features the miniature translates into “Novel Of The Pear” in English. Thus the heart shaped object would be a pear; the conclusion that a pear represents a heart is dubious.
Heart failure is a chronic, progressive condition in which the heart muscle is unable to pump enough blood to meet the body’s needs for blood and oxygen. Basically, the heart can’t keep up with its billy o’toole workload. Your body depends on the heart’s pumping action to deliver oxygen- and nutrient-rich blood to the body’s cells. When the cells are nourished properly, the body can function normally.
All the parts of your heart work together to keep blood flowing and send nutrients to your other organs. Conditions that affect your heart are some of the most common types of conditions. Ask your healthcare provider how you can improve your heart health. Coronary heart disease – coronary heart disease happens when the coronary arteries supplying blood to the heart muscle become blocked or narrowed by a build-up of fatty deposits . Coronary heart disease can cause angina and heart attacks. You might not be diagnosed with coronary artery disease until you have a heart attack, angina, stroke or heart failure.
A typical heart has two upper and two lower chambers. The upper chambers, the right and left atria, receive incoming blood. The lower chambers, the more muscular right and left ventricles, pump blood out of the heart.
Valves must open all the way and close tightly so there’s no leakage. Heart disease causes depend on the specific type of heart disease. The heart has four valves — the aortic, mitral, pulmonary and tricuspid valves. They open and close to move blood through the heart. A heart valve may become narrowed , leaky or close improperly .
