Heart sounds are the noises generated by the beating heart and the resultant flow of blood through it. Specifically, the sounds reflect the turbulence created when the heart valves snap shut. In cardiac auscultation , an examiner may use a stethoscope to listen for these unique and distinct sounds that provide important auditory data regarding ...
Wiggers diagram of various events of a cardiac cycle, with 2nd heart sound at bottom. A split S2 is a finding upon auscultation of the S2 heart sound. [1] It is caused when the closure of the aortic valve (A 2) and the closure of the pulmonary valve (P 2) are not synchronized during inspiration. The second heart sound (S2) is caused by the ...
Korotkoff sounds are the sounds that medical personnel listen for when they are taking blood pressure using a non-invasive procedure. They are named after Nikolai Korotkov , a Russian physician who discovered them in 1905, [ 1 ] when he was working at the Imperial Medical Academy in St. Petersburg , the Russian Empire.
Funic souffle (also known as funicular or fetal souffle), is a blowing sound heard in synch with fetal heart sounds, and may originate from the umbilical cord.

A gallop rhythm refers to a (usually abnormal) rhythm of the heart on auscultation. [1] It includes three or four sounds, thus resembling the sounds of a gallop.. The normal heart rhythm contains two audible heart sounds called S 1 and S 2 that give the well-known "lub-dub" rhythm; they are caused by the closing of valves in the heart.
In all adults, including seniors, a normal resting heart rate can be anywhere between 60 and 100 beats per minute. But note: the lower the number within this range, the better.
In a healthy heart, there are only two audible heart sounds, called S1 and S2. The first heart sound S1, is the sound created by the closing of the atrioventricular valves during ventricular contraction and is normally described as "lub". The second heart sound, S2, is the sound of the semilunar valves closing during ventricular diastole and is ...
