What does it mean that sinus rhythm cannot rule out inferior wall myocardial infarction?

Sinus rhythm cannot exclude inferior wall myocardial infarction is a description of the results of the electrocardiogram, which can be suspected of myocardial infarction, and the diagnosis of the specific disease needs to be combined with the history, symptoms, blood cardiac enzyme profiles, and coronary angiography to determine the synthesis.
Sinus rhythm means that the rhythm of the patient’s heart is controlled by impulses from the sinus node, and sinus P waves with a rounded morphology can be seen on the electrocardiogram. Inferior wall myocardial infarction is a type of myocardial infarction, in which acute occlusion of the coronary artery leads to necrosis of the inferior wall myocardium of the left ventricle, and the electrocardiogram is characterized by a bow-backed and upward elevation of the ST segments of the II, Ill, and avF leads, accompanied by T-wave inversion or hyperacuity.
When the electrocardiogram suggests sinus rhythm can not be excluded from the lower wall myocardial infarction, it is necessary to pay high attention to it, go to the regular hospital, combined with the patient’s clinical symptoms, such as whether there is oppressive chest pain, chest tightness, etc., cardiac ultrasound, blood cardiac enzymes and coronary artery angiography and other tests, to clarify the situation of the coronary arteries, and if the diagnosis is confirmed as myocardial infarction, it is necessary to carry out interventional surgery as soon as possible.
