Extractions: A murmur is the medical term used to describe extra sounds that blood makes as it passes through the valves and blood vessels of the heart. It can be heard through a stethoscope between normal heartbeats. Most heart murmurs are completely normal or 'innocent' and cause no symptoms. However, some heart murmurs can be a sign of a heart disorder. What do heart murmurs sound like?

Extractions: Evaluation of Cough in Dogs with Heart Murmurs Clarke Atkins United States The coughing dog commonly presents both a diagnostic and therapeutic dilemma to the practicing veterinarian. This is particularly true in middle-aged to aged small breed dogs, which are often afflicted with chronic respiratory disease and mitral insufficiency, each of which may result in coughing. The problem then becomes one of distinguishing the degree to which respiratory and/or cardiovascular disease are contributing to the cough. This is important because the therapies are quite different, and, in some instances, appropriate therapy for one worsens the other. The cough reflex, usually initiated by irritation of the pharynx, larynx, trachea, and larger bronchi, produces forceful expiration against a closed glottis, followed by sudden release and forced expulsion. This protective mechanism is useful in expelling foreign material, exudates, and organisms from the respiratory tract. It is also fatiguing and irritating to the patient and owner alike. However, suppression of coughing is not indicated in all instances. It is better to alleviate the underlying cause, and using cough suppressants only in a limited number of instances. For this reason, as well as to allow specific treatment and to more accurately prognosticate, a definitive diagnosis is mandatory. Causes of coughing are many, but in the population of dogs under discussion, cough most commonly results from upper airway disease, tracheobronchial collapse, chronic bronchitis of varying etiologies, pulmonary fibrosis, bronchiectsis, pulmonary neoplasia, pneumonia, and mitral regurgitation (the latter, usually but not always with heart failure). In mitral regurgitation, the cause of cough is not entirely clear, but left atrial impingement on the left main bronchus and/or recurrent laryngeal nerve, edema of the respiratory mucosa, interstitial fluid pressure on airways, and excessive bronchial mucous production have all been suggested as being contributory.

Many people with a heart murmur have normal hearts and are still able to exercise and live normal lives. There are many types of heart murmurs. They range from harmless and of no consequence to very serious heart and health problems. A heart murmur may be a symptom of one of the following: Symptoms related to serious heart murmurs vary. Some examples include fatigue, pale complexion, shortness of breath, loss of appetite, heart attack, stroke, fever, and arthritic pain in joints. If you have symptoms such as these, seek medical help. Some people with a heart murmur live their whole lives without any problems. Active lifestyles are maintained and aerobic exercise offers added benefits.

heart murmurs. Our heart pumps blood around our body and to ensure that bloodkeeps moving in one direction, there are valves within our heart.
http://www.irishheart.ie/patientqueries/murmurs.htm

Extractions: IHF Home Patient Queries Our heart pumps blood around our body and to ensure that blood keeps moving in one direction, there are valves within our heart. When these valves shut (like a door) they produce a sound which is heard by the doctor as "Lub Dub". However, if the valves are narrowed or have in a hole in them and thus leak, an additional sound is heard called a murmur. This sound is produced by blood being forced across a narrowed valve or by blood leaking back through a hole in the valve. The murmur may also occur if blood moves rapidly through normal valves in patients with fast heart rates which occur in pregnancy, fever, thyrotoxicosis or anaemia. Murmurs which occur when the heart contracts are called systolic murmurs and those that occur when the heart relaxes are called diastolic murmurs. As mentioned some murmurs occur in normal hearts if the blood moves quickly. Your doctor assesses your murmur and may perform tests to work out if there is a problem with one of your heart valves. Sometimes, the murmur is innocent which means it does not signify any major heart problem. If there is a problem with one of your valves your doctor may decide that no treatment is needed or that you would benefit from drugs or some form of surgery to fix the problem.

http://www.musckids.com/health_library/cardiac/murmur.htm

Extractions: Cardiovascular Disorders Murmurs are sounds made by blood circulating through the heart's chambers or valves, or through blood vessels near the heart. Heart murmurs may be caused by a number of factors or diseases, including the following: Your child's physician will evaluate a murmur based on several factors. Murmurs are analyzed for pitch, loudness, and duration. They also are graded according to their intensity (on a scale of one to six, with one being very faint and six being very loud). Types of murmurs include the following: systolic murmur - a heart murmur that occurs during a heart muscle contraction. Systolic murmurs are divided into ejection murmurs (due to blood flow through a narrowed vessel or irregular valve) and regurgitant murmurs.

Extractions: for CATS USA 2003 ... Health: General A heart murmur is a heart valve problem that is common in older cats. The average cat's heart, weighing less than one-tenth of an ounce, will beat more than 350 million times during a 13-year lifetime. The heart has four chambers with valves that regulate blood flow. The major veins bringing blood to the heart are called the vena cavas. Blood first enters the heart's right atrium, then passes through the tricuspid valve and flows into the right ventricle. The right ventricle contracts and sends blood into the pulmonic artery through the pulmonic valve. Blood then goes to the lungs where it becomes oxygenated. Oxygenated blood from the pulmonic vein enters the heart's left atrium, then passes into the left ventricle via the mitral valve. When the left ventricle contracts, blood shoots out of the heart through the aorta and circulates throughout the rest of the body. The tricuspid and mitral valves regulate blood flow through the heart. In cats, deformities of these valves are the most common congenital cardiac malformations. A murmur, or squishing noise indicates blood is leaking out of the valves during heart contraction. Instead of forming a tight seal, blood escapes around the valve. By listening to the heart with a stethoscope, veterinarians can often detect valve problems. A murmur's intensity and loudness does not correlate with the severity of valve damage. Murmurs are common in older cats. Some kittens are born with murmurs and outgrow them; others have murmurs their entire lives without problems. Though uncommon in cats, some murmurs may progress and lead to congestive heart failure.

Extractions: A heart murmur is an abnormal sound in the heart. Generally, during a routine office visit, the doctor listens to the heart using a stethoscope and can detect if a murmur is present. In most cases, heart murmurs do not affect the person's health and result in some form of irregular blood flow through the heart. Some, however, are due to underlying defects in the heart or its valves and may require treatment.

Diagnosing and treating heart murmurs
http://www.medicalmoment.org/monthly/02-03/cardiology/treatingmurmurs.asp

Extractions: Most heart murmurs require no special treatment other than leading a healthy lifestyle in general - not smoking, reducing stress, eating wisely and exercising regularly. Valvular defects can sometimes be treated medically; however, if the valve is severely diseased or defective, surgery may be recommended to replace the damaged valve(s). The production of murmurs is due to three main factors: (1) high blood flow rate through normal or abnormal orifices; (2) forward flow through a narrowed or irregular orifice into a dilated vessel or chamber; or (3) backward or regurgitant flow through an incompetent valve, septal defect, or patent ductus arteriosus (abnormal opening between the aorta and pulmonary artery). A heart murmur may have no pathological significance or may be an important clue to the presence of valvular, congenital, or other structural abnormalities of the heart. Most systolic heart murmurs do not signify cardiac disease, and many are related to physiological increases in blood flow velocity.

Extractions: The heart has four chambers two upper chambers (called atria) and two lower chambers (ventricles). The heart has valves that temporarily close to permit blood flow in only one direction. The valves are located between the atria and ventricles, and between the ventricles and the major arteries from the heart. Normal heart sounds are called S1 and S2. They are the "lubb-dupp" sounds that are thought of as the heartbeat. These sounds are produced when the heart valves close. Because the heart is also divided into a "right side" and a "left side", sometimes these sounds may be somewhat divided most commonly noted is a "split S2", caused when the right and left ventricles contract at very slightly different times. This is a normal finding, but occasionally the nature of the split can indicate an abnormality such as enlargement of one of the ventricles.

Extractions: Heart Murmurs My doctor just told me that my child has a heart murmur. What is a heart murmur? When your family doctor or pediatrician checks your child, he or she listens to the heart. The doctor may then detect an abnormal sound coming from the heart, and call it a heart murmur. There are several different causes for heart murmurs in children. Problems with heart valves or holes in the heart may cause heart murmurs. Children often have heart murmurs even without any problem with the heart. Such murmurs are called innocent murmurs. Are all murmurs dangerous? Unless the murmur is due to a significant problem with the heart, the murmur is not really dangerous. Innocent heart murmurs are never dangerous. Will my child "outgrow" the murmur? Certain murmurs do disappear as the child grows up. Innocent murmurs often disappear in older children. Murmurs due to 'holes' inside the heart may also disappear if the holes close as the child grows up. Does my child need to see a specialist?

Extractions: Charlottesville , 02 July 98 Researchers at the University of Virginia have designed a stethoscope solution for tele-auscultation. Paediatric cardiologists will use the system to diagnose the heart murmurs of children in distant locations. Cardiac specialists have assessed the telemedicine stethoscope and judged the results to be very positive. The system is based on the use of ISDN lines for the sound transmission. The team has succeeded in recording the full spectrum of audible sounds from 20 to 20.000 Hz. This achievement outperforms the capacity of every currently existing sound or video capture card. The separately installed ISDN lines enable both the transfer and reception of the Dolby digital sounds. At the remote site, the assistant puts an E-scope on the child's chest and connects the device to a Cardionics Simulscope. In turn, the Simulscope is being interfaced to a Dolby Digital Encoder, in order to adapt the sounds for remote transmission. The Encoder is being linked to an Adtran ISU 128, which performs the actual transfer of the audio message over a single ISDN line. The message is being received at the site of the University of Virginia through another ISDN line by means of a second Adtran ISU 128. First, the data is introduced into a Dolby Digital Decoder to turn the information into audible sounds. The decoder connects with the University Cardionics Simulscope.
Heart Murmurs In Children - Keep Kids Healthy
heart murmurs are a very common finding in children. Most of these are innocentheart murmurs, which are not associated with any problems in the heart.
http://www.keepkidshealthy.com/welcome/commonproblems/heartmurmurs.html

Extractions: Main Common Problems Heart murmurs are a very common finding in children, and it is currently thought that up to 50-100% of children will have a murmur at some time in their childhood. Most of these are innocent heart murmurs , which are not associated with any problems in the heart. Innocent murmurs may not always be heard at each doctor visit, and they are more common if your child has a rapid pulse, such as occurs with a fever, after activity or if your child is anxious about being at the doctor's office. They do not require any treatment and children with innocent heart murmurs usually don't need to take antibiotics before dental procedures. Murmurs can also less commonly be caused by structural abnormalities in the heart, such as a hole in the wall of the heart (ASD or VSD), infections, a faulty valve, or a blockage. These types of murmurs can usually be detected by a detailed physical exam, which will characterize the location of the murmur, how loud or intense it is, its timing, any changes that occur in the murmur after activity or position changes, and will include an examination of your child's liver to see if it is enlarged, and your child's pulses and blood pressure.
