Systole-diastolic murmur

Systole-diastolic murmur (SDS) is a loud, continuous heart sound that occurs during heart contractions when pressure in the left chambers of the heart increases. This condition is characterized by difficulty in the outflow of blood from the left ventricle during diastole. Murmurs can be the result of heart pathology or be associated with other diseases. They can cause discomfort, pain in the patient, or affect his ability to work. Depending on the reasons leading to SDS, it can manifest itself in different ways and have different characteristics.

Causes of SDS The main cause of systolic murmur is damage to the valvular apparatus of the heart (with endocarditis, aortic or mitral valve defects). It can appear with mitral prolapse syndrome. The causes of diastolic murmur are directly related to the presence of atherosclerosis of the coronary arteries and impaired blood supply to the heart muscle, which contributes to myocardial dystrophy, the formation of electrical instability, arrhythmias, tachycardia, heart block and the replacement of cardiomyocytes with connective tissue. Noise in the diastolic zone can also occur against the background of inflammatory diseases of the myocardium, diffuse changes in the heart, or with dissection of the interventricular septum. Recognition of murmurs Systole murmurs occur in almost every second case of cardiovascular pathology. It can be diagnosed by a cardiologist by auscultation or
