which valve is clearly heard wen the apical heart beat is ausculated?

Usually the mitral valve.

I also have MVP.  In my case, the person doing the ECG showed me the fault.  I was able to see the valve failing and allowing blood to flow in the wrong direction.  I'd get another ECG done and request to see the result.  It should be easy as it's just a matter of having them point it out to you on the screen.  I wish you all the best!

Yes, see a doctor and let them know how often it happens (keep a journal) and ask for a 24hr halter monitor.  I had similar incidents, and my old Dr. didn't do squat...said it was my smoking.  I switched dr's, she suggested the monitor, they saw something, did further tests and i found out I have a defective heart valve, from birth.  Not to scare you...I'm fine now...no meds, no surgery.  But have it checked out.

Functional heart murmurs caused by rushing of blood through the valve are very common. I think your symptoms are mental rather than organic.

Juno406 has given you the essential answer.  \n\nDuring systole the pulmonary (pulmonic) & aortic valves are open.  The tricuspid & mitral valves are closed.  \n\nDuring diastole the tricuspid & mitral valves are open.  The pulmonary & aortic valves are closed.

The mitral valve is also known as the bicuspid valve and is found between the ventricles on the left side of the heart.\n\nMitral Valve Prolapse occurs when abnormalities in the mitral valve leaflets, chordae tendinae, or papillary muscles allow prolapse of the mitral valve leaflets backward into the LA during ventricular systole.\n\n• Abnormal mitral valve mechanism which results in billowing of one or both mitral leaflets into the left atrium towards the end of systole.\no  also known as Barlow’s syndrome, as well as “floppy”  \n   or “billowing” mitral valve.\no  the leaflets become enlarged or thickened, and the \n   chordae tendinae become elongated. these changes allow \n   the valve leaflets to billow upward into the LA during \n   ventricular systole.\no  on auscultation, a mid-systolic click is heard\n\nMitral valve prolapse symptoms\n• Most patients: None\n• Chest pain\n• Palpitations\n• Easy fatigability\n• Arrhythmias\n• TIA\n• MR\no mitral valve prolapse pt’s have artherosclerotic problems\n\n\nabove is a little more info compliments of my Medical Surgical notes

It stops the heart from beating.

The Aortic valve close or prevents a back flow of blood during diastole at this same time the the mital valve is open as the at atrium is contracting.

A-fib is an irregular and rapid impulse from discharged from multi ectopic atrial foci.  A-flutter is an arrhythnia origininating in the atrium characterized by rapid, REGULAR atrial activity.  On an EKG we do not see "P" waves in atrial fib and the rate may be rapid or slow, but it is irregular.  A-flutter can be very rapid or slow depending how the ventricle responds to the atrial impulses.  The "P" waves in atrial flutter are very visable and look "saw toothed".  Each can be dangerous.  When a person has a-fib there is a great risk of blood clots.

look at this 3D pic then read\n\nhttp://library.thinkquest.org/C003758/rotate.htm\n\nIn the human body, the heart is normally situated slightly to the left of the middle of the thorax, underneath the sternum (breastbone). The heart is usually felt to be on the left side because the left heart (the left part of the heart) is stronger (it pumps the blood out). The heart is enclosed by a sac known as the pericardium and is surrounded by the lungs.Betwen the pericardium and the heart there is a serous fluid to reduce friction during heart contractions. The apex is the blunt point at the base of the heart. A stethoscope can be placed directly over the apex and count the beats. In normal adults, its mass is 250-350 g (8-11 oz), but extremely diseased hearts can be up to 1000 g (2 lb) in mass. It consists of four chambers, the two upper atria (singular: atrium ) and the two lower ventricles. On the right is a picture of a fresh human heart which was just removed from a 64 year old British gentleman. The mass for a thin white male is usually 270-300 grams (9-11 ounces) with little fat.\n\nA septum divides the right atrium and ventricle from the left atrium and ventricle, preventing blood from passing between them. Valves between the atria and ventricles (atrioventricular valves) maintain coordinated unidirectional flow of blood from the atria to the ventricles. The ventricular systole consists of the contraction of the ventricles and flow of blood into the circulatory system. Again, once all the blood empties from the ventricles, the pulmonary and aortic semilunar valves close. Finally complete cardiac diastole involves relaxation of the atria and ventricles in preparation for refilling with circulating blood.\n\nThe function of the right side of the heart (see right heart) is to collect deoxygenated blood from the body and pump it into the lungs (pulmonary circulation)so that carbon dioxide can be dropped off and oxygen picked up. This happens through a process called diffusion. The left side (see left heart) collects oxygenated blood from the lungs and pumps it out to the body (systemic circulation). On both sides, the lower ventricles are thicker than the upper atria.\nOxygen-depleted or deoxygenated blood from the body enters the right atrium through two great veins, the superior vena cava which drains the upper part of the body and the inferior vena cava that drains the lower part which drains the portal cyrculation too full with nutrients to nourish the body. The blood then passes through the tricuspid valve to the right ventricle. The right ventricle pumps the deoxygenated blood to the lungs, through the pulmonary artery. In the lungs gaseous exchange takes places and the blood releases carbon dioxide into the lung cavity and picks up oxygen which is called external respiration. The oxygenated blood then flows through pulmonary veins to the left atrium. From the left atrium this newly oxygenated blood passes through the mitral valve (also called the bicuspid valve) to enter the left ventricle. The left ventricle then pumps the blood through the aorta to the entire body. Even the lungs take some of the blood supply from the aorta via bronchial arteries.\n\nThe left ventricle is much more muscular, which is 1.3 - 1.5 cm (.5-.6 in) thick, than the right, 0.3 - 0.5 cm ( .1-.2 in) thick, as it has to pump blood around the entire body, which involves exerting a considerable force to overcome the vascular pressure. As the right ventricle needs to pump blood only to the lungs, it requires less muscle.\n\nEven though the ventricles lie below the atria, the two vessels through which the blood exits the heart (the pulmonary artery and the aorta) leave the heart at its top side.\n\nThe contractile nature of the heart is due to the presence of cardiac muscle in its wall which can work continuously without fatigue. The heart wall is made of three distinct layers. The first is the outer epicardium which is composed of a layer of flattened epi

a heart murmur is NOT an irregular heart beat at all.  The heart has four valves use to separate the four chambers of the heart from each other.  At different points during a heat beat different valves open and close to allow the blood to only travel in a forwards (not a reverse) direction.  A murmur occurs (usually, not always, there are other causes) because of a problem with one of the valves.  The valve could be failing to close fully, causing a regurgitant murmur from the leak.  Alternatively, the valve could be obstructed or failing to open all the way, causing a stenotic murmur.

Irregular heart beat is called ARRHYTHMIA's\n\ntypes include :\nExtrasystole\nventricular premature contractions\nAtrial fibrillation\nAtrial Flutter \nComplete heart block\n\nBut murmurs are the sounds heared over the heart because of any disturbed BLOOD FLOW either due to irregular beats or incompetent valves

The first heart sound is due to the closing of the atrioventrical valves (i.e. the mitral and tricuspid valves). It is due to the leaflets of the valves snapping together under pressure, just before the ventricles contract. \n\nThis is generally louder than the closing of the pulmonary and aortic valves, which cause the dup sound.

Just to the left of the center of the thorax, beneath the sternum.\nHave a look at the excellent anatomical diagrams on the following site (navigate to 'Auscultation' for the specific picture you want):

Prolapse: The valve itself prolapses somewhat. Blood stays in ventricle. Regurg: Blood regurgitates into the atrium (kind of like food regurgitates from the stomach to the mouth when you vomit). As to treatments, symptoms, etc. I'm only a third year, and cardiology was NOT my strong point! I do know that proplapse can progress to include regurge.

I notaced there isnt a whole lot of answers for this one. For those of you who don't know what it is or what it does. The pericardium is the fluid filled sac that surrounds the heart and the proximal ends of the aorta, vena cava and the pulmonary artery. \nIt keeps the heart contained in the chest cavity. \nPrevents the heart from overexpanding when blood volume increases and limits heart motion.\nTo answer your question: (I had to look this up)\nParietal pericardium has been determined to be 1-2mm by anatomic studies but it is non-uniform in thickness.
