When the heart works well, the body will perform better. If breathing is very smooth, it means that the heart is working normally. Many people have difficulty breathing when the heart function declines. It may be that after the heart function declines, they don't have enough strength to maintain blood circulation, so they will have difficulty breathing. If breathing is very smooth and there is no feeling of shortness of breath, it means that the heart is functioning normally. When the heart function declines, the heart does not have enough strength to maintain normal blood circulation, which easily leads to the inability to supply the blood needed by brain tissue. The common manifestation is hypoxia and ischemia of brain tissue.
Facial skin remains ruddy and healthy, which is a common sign of normal heart function. When the heart function declines, the blood supply is blocked, which makes many people's facial skin pale and bloodless. Therefore, the change of facial expression can be used to judge whether the heart function is healthy or not. When the heart function declines, arrhythmia and myocardial ischemia may occur, and there is not enough nutrition to provide, so many people are prone to sleep quality decline, and even prone to palpitations when sleeping at night.
