 | | The splitting of the second heart tone varies with the phases of respiration. | | | This means that left sided murmurs Similar to inhalation increased blood flow to the right side of the heart can be facilitated by having the patient lie supine and raising their legs up to a 45 degree angle. | | | It is physiological to hear the splitting of the second heart tone by younger people and during inspiration. |

| | Heart Murmurs - Texas Heart Institute Heart Information Center |
| | If your heart murmur is caused by disease of the valve itself (intrinsic valve disease) or other heart defects, medicines or surgery may be needed. | | | Usually the murmur is found during a physical exam for other symptoms, such as chest pain, shortness of breath, fatigue, or the presence of a blue coloring to the skin or fingertips (called cyanosis). | | | In most cases, your doctor will be able to hear your heart murmur by using a stethoscope to listen to your heart (a technique called cardiac auscultation). |

| | Normal Heart Sounds |
| | A diseased heart is simply not able to pump all of the blood delivered to it--a condition called cardiac failure. | | | The heart rate is also influenced by the sex and the age of an individual. | | | Such a procedure involves the implantation of the pacemaker beneath the skin and connection of its electrodes to the heart. |

| | Reviews of Understanding Pediatric Heart Sounds by Steven Lehrer |
| | Also, the technique of dissection, which involves concentrating on one portion of the cardiac cycle or one heart sound to the exclusion of others, is often beneficial but is not discussed in the text. | | | As pointed out by the author, functional benign heart murmurs are common in children, yet perplexing for the practitioner to identify. | | | The title of this publication seems quaint for the 1990s, at a time when technology has taken over from the stethoscope and a child with a complex heart malformation can be evaluated and surgically treated without the bell ever touching the chest. |

| | It is best heard at the apex by having the patient lay on his left side and using the bell portion of the stethoscope applying very light pressure to the chest. | | | Listening at the mitral area, of the patient’s chest, you can hear the sound of the mitral and tricuspid valves closing. | | | It can be heard at any sight of ausculation, but it is best heard at the apex with a diaphragm firmly pressed against the patient's chest. |

| | S2 A normal second heart sound (S2) is produced by the pressure changes and vibration of valves and contiguous structures induced by motion of the aortic and pulmonic leaflets toward their respective ventricles. | | | S3 The physiologic third heart sound (S3) is a low-pitched vibration occurring in early diastole during the time of rapid ventricular filling. | | | The physiologic S3 occurs just after A2 and is best heard at the apex with a patient in the left semilateral position. |

| | He is thinking of using signal analysis to study left ventricular assist devices—devices placed in the heart after congestive heart failure which cut down on the energy the heart exerts to pump, allowing it to heal more quickly. | | | That's why your heart rate increased—your sympathetic responses strengthened for a few seconds. | | | Chander remarks, "The autonomic nervous system affects the entire body—it affects the digestive system, it affects respiration—so the fact that we're just trying to heal the heart with these devices and we're seeing restoration to a normal state everywhere in the body … that's a very positive thing." |

| | The third heart sound, which is sometimes heard in children with thin chest walls or in patients with left ventricular failure, consists of a few low-intensity, low-frequency vibrations heard best in the region of the apex. | | | The vibrations are engendered in part by the abrupt rise of ventricular pressure with acceleration of blood back toward the atria, but primarily by sudden tension and recoil of the AV valves and adjacent structures with deceleration of the blood resulting from closure of the AV valves. | | | The vibrations of the ventricles and the contained blood are transmitted through surrounding tissues and reach the chest wall, where they may be heard or recorded. |

| | A heart murmur may indicate that there is a heart problem or may be due to normal blood flow. | | | Most of the time heart murmurs are normal and do not indicate that there is anything wrong with the heart. | | | A heart murmur is a swishing or a whistling sound that the doctor hears when he listens to your child's heart with a stethoscope. |

They are named for the valve that they best assess. | | | Heart sound auscultation is just one part of your assessment. Correlate it with the patient’s clinical condition, and presenting symptoms to best understand what your assessment means for this patient. |
