What causes the lubb dupp heart sounds that are heard while taking a apical pulse?
The closure of mitral and tricuspid valves causes the first heart sound. The second heart sound is produced by the closure of semilunar valves (pulmonic and aortic valves).
True or false a sphygmomanometer is used to take the apical pulse?
False, because the apical pulse is the heartbeat and is heard with a stethoscope. The sphygmomanometer is used to take the pulse on the arm.
Why abnormalities of the heart is better detected by ausculation rather than electrocardiography?
with electrocardiography and auscultation different abnormalities can be detected. For example, ecg can show abnormal rythms (due to the damage to the conductive tissue or high level of potassium). But cardiac mummurs can only be heard (they're because of valvular problems)
Which part of the heart makes the heartbeat sound?
A heartbeat produces the familiar "LUB-DUP" sounds as the chambers contract and the valves close. The first heart sound, "lub," is heard when the ventricles contract and the atrioventricular valves close. This sound last longest and has a lower pitch. The second heart sound, "dub," is heard when the relaxation of the ventricles allows the semilunar valves to close.
Your 4 yr old occasionally states his heart hurts and points to his heart you also listened to him w your stethoscope and heard some pretty regular pauses in his heart rate w a questionable murmur?
What if it is his feelings? Or, if it is his stomach? Anything occasional is probably not to worry about. Keep a diary noting when he says that, list the foods he ate and other activities. Take the diary to his next physical.

What is discoverable using an amplified stethoscope?
The sounds of the Heart, lungs, circulatory and gastrointestinal systems are heard using the amplified stethoscope. It makes it easier for a medical professional to hear the sounds that are produced by these systems in the body.
Sounds heard over a blood vessel when the vessel is partially compressed?
These sounds are called bruit and are listened to using a stethoscope. Bruit indicates partial arterial obstruction.
What syndrome has symptoms of abnormal sounds heard from the chest when listening with a stethoscope which indicate that the mitral valve is not closing properly?
Barlow Syndrome
What can be learned from the Valsalva maneuver?
when a doctor listens to the chest with a stethoscope during the Valsalva maneuver, characteristic heart sounds are heard. Variations in these sounds can indicate the type of abnormality present in the heart.
When heard by a stethoscope where is heartbeat most easily heard?
umblicus
How is atelectasis diagnosed?
When the doctor listens to the lungs through a stethoscope (ausculation), diminished or bronchial breath sounds may be heard. By tapping on the chest (percussion) while listening through the stethoscope, the doctor can often tell if the lung is collapsed
What is korotkoff sounds?
Korotkoff sounds are the sounds heard through a stethoscope during the measurement of blood pressure. They are created by the turbulent flow of blood through the constricted artery when the cuff is gradually deflated. These sounds are used to determine systolic and diastolic blood pressure readings.
What causes the sounds that are normally heard when listening to the heart through a stethoscope?
The sound is caused by the closing of valves in the heart.
What can cause the breathing problem called rales?
Pneumonia is the typical condition that causes rales. Rales sound a little like Rice Krispies when heard through the stethoscope.
