What causes a weak pulse?

The problem of weak pulse actually needs to be taken seriously, because the pulse is affected by the activity of the heartbeat. If the pulse is too weak, it may indicate that your heart function will degenerate to a certain extent.

1. A weak pulse is affected by the activity of the heartbeat. The activity of the heartbeat is directly reflected in the weakness of the pulse, which to a certain extent reflects a certain degree of degeneration of your heart function. The heartbeat rhythm is regular and if the heart beats irregularly, we call it arrhythmia. From this perspective, sinus arrhythmia is the most common type of arrhythmia, which is caused by the signal from the sinoatrial node not being completely regular.

2. However, most of these arrhythmias are respiratory sinus arrhythmias , which is a normal physiological phenomenon. Its characteristic is that it changes with breathing. The heart rate may increase by several beats when inhaling and slow down by several beats when exhaling. Its fast and slow cycle is exactly equal to one breathing cycle, and the heart rhythm becomes regular when holding the breath. This "sinus arrhythmia" that changes with breathing is completely normal and there is no need to worry or treat it.

3. It is recommended to go to the hospital for an electrocardiogram to see if there are any abnormalities, and to check the heart color Doppler ultrasound to see if there are any abnormalities in heart function, and then receive relevant treatment. Pay attention to strengthening nutrition in daily life. Analysis of problems: A weak pulse is mainly due to weak myocardial contractility, and some cannot even cause peripheral vascular fluctuations. It can also be due to excessive peripheral resistance that prevents blood vessels from filling, which can also lead to a weak pulse.
