What symptom does heart have murmur to have?
summary
Heart murmur is caused by the turbulence of blood flow in the heart cavity or large blood vessels, which makes the ventricular wall, heart valve or blood vessel wall vibrate; It can also be caused by the increased speed of blood flow through the heart cavity or heart valve.

What symptom does heart have murmur to have?
Pericardial friction sound is a high-key sound, similar to the sound produced by leather friction. It is often heard between 3-4 ribs on the left edge of sternum. It can occur in systole, diastole or stage II. It is alternating and can cover up the heart sound. Generally speaking, it is easy to hear when sitting and leaning forward (holding breath), and the sound increases when pressing the chest part of stethoscope. When the friction sound is bright and rough, it is similar to systolic murmur, but it exists for a short time, only a few hours to a few days, which is different from murmur. Pericardial fricative sound is similar to pleural fricative sound in auscultation, but it can disappear when breathing stops, and pericardial fricative sound still appears with heart beat.
When the heart beats, it squeezes the lung near the heart to make the air flow in the lung, which mostly occurs in the systole. The murmur is limited in mid systolic phase, with high pitch and easy to be heard on the right apex and along the left edge of the heart. It is clear when inhaled. But suddenly disappeared. When pleural and mediastinal adhesions are extensive, it is also seen in normal people.
When the artery is dilated (e.g. aneurysm) or stenosed (e.g. atherosclerosis, constrictive arteritis tip), there is no need for pressure at the lesion site, which is equivalent to the heart systolic noise. When continuous murmurs and aortic insufficiency can be heard in the fistulas of arteriovenous fistulas, two murmurs can be heard by gently pressing the brachial artery or femoral artery with the chest piece of stethoscope. Systolic murmurs of aortic stenosis can be heard along the blood stream at the right subclavian artery or carotid artery. Continuous murmurs can also be heard in the varicose veins.
matters needing attention
In short, it must be emphasized that when you know that your heart has murmur, first of all, you should ask your doctor to make sure whether it is physiological or pathological, systolic or diastolic. If it is a physiological systolic murmur, then the heart is not necessarily sick, there is no need for tension, and there is no need for treatment.
