What causes the sound the heart makes?
Heart sounds are created from blood flowing through the heart chambers as the cardiac valves open and close during the cardiac cycle. Vibrations of these structures from the blood flow create audible sounds — the more turbulent the blood flow, the more vibrations that get created.
What heart sound is louder?
The first heart sound has a booming quality and is lower-pitched, duller, and longer than the second heart sound. It is usually louder at the apex than is the second sound. At the base, however, both components of the second sound are normally louder than the first sound (see Chapter 23, The Second Heart Sound).
What is an abnormal sound of the heart?
Abnormal heart sounds are called heart murmurs. These sounds can include rasping, whooshing, or blowing sounds. Heart murmurs can occur during different parts of your heartbeat.

What is the difference between S3 and S4 heart sounds?
The main normal heart sounds are the S1 and the S2 heart sound. The S3 can be normal, at times, but may be pathologic. A S4 heart sound is almost always pathologic. Heart sounds can be described by their intensity, pitch, location, quality and timing in the cardiac cycle.
How many heart sounds are abnormal?
62 Abnormal Heart Sounds and Murmurs | Medical Council of Canada.
How is Blaufuss sound builder related to cardiac auscultation?
Blaufuss Sound Builder (Teaching Cardiac Auscultation) Sounds related to other conditions, such as mitral insufficiency, aortic stenosis, aortic insufficiency, and patent ductus arteriosus, can be generated and correlated with an accompanying phonocardiogram and electrocardiogram.
Is there an app for Blaufuss sound builder?
The Blaufuss Sound Builder application, which can be downloaded to an iPhone or iPad, provides an alternative approach. The uniqueness of this application is that there is correlation with the electrocardiogram and phonocardiogram and that different heart sounds and murmurs can be built around the first and second heart sound.
How to identify the first and second heart sounds?
This interactive quiz will test your ability to identify correctly the first and second heart sounds, extra sounds, diastolic and systolic murmurs in recordings of actual patients, using a computer animation of the carotid pulse for timing.
