What should left atrium ache do to check?

summary

The left atrium, which forms the majority of the heart floor, has four entrances and one exit. On both sides of the posterior wall of the left atrium, there are a pair of pulmonary vein orifices, which are the entrances of the left and right pulmonary veins; There is a left atrioventricular orifice under the left atrium, leading to the left ventricle. The fresh blood after gas exchange from the lung flows into the left atrium through the pulmonary vein, and then into the left ventricle through the left atrioventricular orifice. There is a mitral valve (left atrioventricular valve) at the left atrioventricular orifice, and the blood flows into the left ventricle through the left atrium.

What should left atrium ache do to check?

1. Angina pectoris should be squeezing and constriction, compression and suffocation, heavy and stuffy pain, not knife like sharp pain or scratch pain, short needle like or electric shock like pain, or chest tightness feeling day and night. In fact, it's not colic. In a few patients, it can be burning, tension or shortness of breath, accompanied by throat or upper airway squeeze. The pain or discomfort was mild at the beginning, increased gradually, and then disappeared gradually. It was rarely affected by posture change or deep breathing.

2. The pain or discomfort is usually located in or near the sternum, or at any level between the upper abdomen and the pharynx, but rarely above the pharynx. Sometimes it can be located in the left shoulder or arm, occasionally it can be accompanied by the right arm, mandible, lower cervical spine, upper thoracic spine, left interscapular or suprascapular area, but it is rarely located in the left armpit or left chest. For the distribution of pain or discomfort, patients often need to use the whole palm or fist to indicate, and rarely use the fingertip of one finger to indicate.

3. Effect of nitroglycerin: if the sublingual nitroglycerin tablet is effective, angina pectoris should be relieved within 1-2 minutes (or 5 minutes, the patient's estimation of time may not be accurate enough). Nitroglycerin may not be effective for supine angina pectoris. When evaluating the effect of nitroglycerin, we should also pay attention to whether the drugs used by patients have failed or nearly failed.
