What reason is old person heartbeat slow

summary

Bradycardia refers to the heart rate below 60 beats per minute, also known as bradycardia. Elderly people like my grandfather are more likely to suffer from this kind of disease. Most of them don't understand the causes of the disease. Let's take a look at the causes of slow heartbeat.

What reason is old person heartbeat slow

First, the causes of bradycardia are common in: vagal hyperfunction. When the vagus nerve is excited, its terminals can release a substance called "acetylcholine", which can inhibit the heart and slow down the heart. Bradycardia caused by vagal hyperactivity, rhythm is mostly neat, generally 30-40 times per minute. Most of them are old people.

Second: sick sinus syndrome can slow down the heart beat because the pacemaker of heart beat, sinus node, can't make impulse or delay impulse. The most common causes are cardiomyopathy, coronary heart disease and degenerative diseases of heart conduction system in the elderly. Patients with sick sinus syndrome sometimes have only 30 beats per minute.

Third: serious atrioventricular block, that is, the impulse wave from the sinus node of the pacing point can not be transmitted to the atrioventricular node and blocked, at this time, the ventricle has to compensate to send out its own impulse, so the heartbeat is quite slow. Once complete atrioventricular block occurs, the heartbeat is only about 20 times per minute, and dizziness occurs due to the obvious decrease of cardiac output, which directly affects the blood supply to the brain To cause syncope or convulsion.

matters needing attention

The patients with bradycardia usually eat less salt and fat, supplement more dietary fiber and vitamins, and supplement more trace elements.
