Weak pulse is a weak pulse beat, which can be seen in thin and weak people, and some patients may have coronary heart disease, heart failure, peripheral vascular disease, etc. 1. Weak pulse can be seen in normal people, thin women are more common, low blood pressure level, the heart contraction force is relatively weak, can be manifested as a weak pulse, but there is no other heart-related symptoms. 2. Coronary heart disease: patients with coronary heart disease will experience myocardial ischemia, severe myocardial ischemia will lead to a decrease in myocardial contractility and a decrease in the heart’s ejection volume, resulting in a weak pulse. 3. Heart failure can also lead to weak pulse, heart failure patients themselves there is a decline in myocardial contractility, due to the decline in the heart’s ejection capacity, there can also be a weak pulse. 4. Peripheral vascular disease: arteritis can lead to peripheral arterial stenosis, vascular resistance increases, blood flow decreases, resulting in a weakened radial artery beat. Weak pulse is more common in the clinic, such as pericardial effusion, arteriosclerosis, etc. If you have symptoms, you should go to the hospital in time to clarify the specific cause.
