How is chest tightness, shortness of breath and weakness of limbs?

Patients with chest tightness, shortness of breath and weakness of limbs should consider the following points:

First of all, ion disorder should be considered, and patients with hypokalemia will have obvious clinical symptoms.

Second, in addition, for endocrine and metabolic diseases, the above situation mostly occurs when thyroid function is low, parathyroid function is low, and adrenal cortex function is insufficient.

Thirdly, if the patient has cardiogenic diseases, such as unstable angina pectoris of coronary heart disease, heart failure and arrhythmia, the patient will have the above clinical symptoms.

Fourth, severe myocarditis and cardiomyopathy can also lead to the above situation. For respiratory diseases, it is common in acute large-scale respiratory infection, such as lung infection and pleurisy. At this time, there will also be chest tightness, shortness of breath and general fatigue, but it is usually accompanied by an increase in body temperature. Chest tightness, shortness of breath and weakness of limbs may be caused by cardiac insufficiency or heart failure. Heart failure will lead to the decrease of cardiac ejection, lead to insufficient blood supply to the whole body, lead to weakness of limbs, and heart failure will cause hypoxia, leading to chest tightness and shortness of breath. In addition, it may be a serious arrhythmia, such as atrioventricular reentrant tachycardia. Excessive heart rate will affect the ejection function of the heart, resulting in insufficient blood supply to the whole body. It may also be caused by lung diseases, such as acute asthma attack, and it may also lead to hypoxia, leading to weakness of limbs, chest tightness and shortness of breath. In addition, we should pay attention to the possibility of hypokalemia. Hypokalemia can lead to limb weakness, mainly the decrease of neuromuscular excitability. Hypokalemia can also cause arrhythmia, decreased myocardial contractility and decreased cardiac function, leading to chest tightness and shortness of breath.
