The causes of an ejection click are the rapid opening of your aortic or pulmonary valves which are valves that are designed to open smoothly.
Although in certain conditions the aortic or pulmonary valves can create a click as they open which is called an ejection click.
An ejection click is a systolic heart sound occurring early in systole and is also often associated with aortic stenosis or pulmonary stenosis.
Ejection clicks often indicate that you have structural abnormalities in the valves like aortic stenosis, structural abnormalities in the bicuspid aortic valves or even dilation of your aorta or pulmonary artery.
The difference between an opening snap and an ejection click is that an opening snap is a diastolic heart sound caused by the sudden opening of a stenotic mitral valve in early diastole.
The main difference is their timing within the cardiac cycle: opening snap is in diastole, while ejection click is in systole.
A ventricular gallop is an extra heart sound that occurs during the relaxation phase of the heart cycle also known as diastole.
The ventricular gallop is also known as the S3 heart sound and is characterized by a low frequency and dull sound that is heard after the S2 sound which is the closing of your aortic and pulmonic valves and the sound can also indicate various heart conditions and most particularly heart conditions that involve ventricular filling.
The opening snap sound is a high pitched, sharp sound that is heard just after the second heart sound and is often associated with mitral stenosis which is a condition in which the mitral valve narrows.
An opening snap is a high pitched and sharp sound that is heard in early diastole, which is the phase of the cardiac cycle when your heart ventricles are filling up with blood.
The opening snap is often associated with the forceful opening of a stenotic "narrowed", but mobile mitral valve and is a key finding in diagnosing mitral stenosis.
The cause of the opening snap is when the mitral valve, which is typically narrowed or thickened due to conditions such as rheumatic heart disease, opens up suddenly.
The second heart sound-opening snap interval may be up to 12 hundredths of a second.
And the opening snap is also associated with a loud first sound and the diastolic murmur of mitral stenosis.
