Noise Spindle-shaped

Spindle noise

Fusiform murmur or systolic murmur is a sound signal that is heard against the background of the heart rhythm and is characterized by minimal intensity after the first sound, a gradual increase in intensity towards mid-systole and a decrease at the end.

The shape of the noise is spindle-shaped or diamond-shaped, which is caused by a gradual increase and decrease in sound intensity. Fusiform murmurs can be both pathological and physiological and can manifest themselves in various heart diseases.

Pathological fusiform murmurs can signal problems such as heart valve defects, aortic stenosis, mitral valve stenosis, aortic atherosclerosis, myocardial infarction and others.

Physiological fusiform murmurs can be associated with cardiac rhythm patterns, for example, during physical activity or emotional stress.

To diagnose fusiform murmurs, it is necessary to perform a phonocardiogram and consult a cardiologist.

Spindle noise

The fusiform murmur is of a systolic type, characterized by maximum intensity in the region of the second tone, a decrease in intensity towards the period with the maximum tone and the end of the systole period. It is detected using phonocardiography (PCG) in the descending segment of the first ECG tone. First described by Willem Tristram Bard in 1964. This is a method of analyzing the sound waves generated by heartbeats. It involves measuring arterial blood pressure and converting it into sound vibrations using a piezoelectric sensor that is attached to the patient's chest.
