What causes premature heart beats? What is a premature heart beat

Premature beats, which are caused by premature impulses from ectopic pacemakers, are the most common arrhythmias. Premature heart beats can occur in normal people, and a few years ago, my nephew had this problem, and I went to all the famous doctors, but there was still little improvement. Later, after being introduced by others, I went to the hospital to open this ginseng pine heart capsule, and the situation has been greatly improved.

It is used for premature ventricular contractions of coronary heart disease caused by qi and yin deficiency and cardiac stasis, symptoms such as palpitations, shortness of breath and fatigue, aggravation of movement, chest pain, insomnia and dreams, night sweats, fatigue and lazy speech, etc.

Premature cardiac beats are common arrhythmias, so what is the cause of premature cardiac beats, let's find out together.

Clause.

1. Abnormal impulse formation caused by abnormal automaticity

Under certain conditions, such as when sinus impulses reach an ectopic pacemaker, the Weidensky phenomenon reduces the threshold potential and changes the diastolic depolarization slope, causing premature pulsation.

The permeability of the membrane of the diseased atrium, ventricle or urakino fibroblast to different ions changes, which makes the fast-responding fibers transform into slow-responding fibers, and the automatic depolarization of diastole is accelerated, and the automaticity is enhanced, resulting in premature beats.

When the sinus impulse reaches the ectopic pacemaker, the threshold potential level is shifted downward, so that the diastolic depolarization of the ectopic pacemaker reaches the threshold potential before the basic rhythm pacemaker, causing premature contractions.

Clause.

2. Reentry phenomenon - circular reentry or focal micro-reentry

If the reentry route is the same, the premature pulsation pattern is the same; If conduction velocity is consistent in reentrant, the premature beat is paired with the previous beat.

Clause.

3. Parallel shrinkage

Clause.

Fourth, trigger excitement

Premature heart beats are the premature beating of the heart, and some people with heart disease have a relatively higher chance of having a premature heart beat, but for normal people, let's talk about what causes premature heart beats.

1.First, premature beats can occur in normal people. Emotional agitation, nervousness, fatigue, indigestion, excessive smoking, drinking alcohol or drinking strong tea can all cause attacks, and there can be no obvious cause, so it is recommended that you can pay attention to your own maintenance in normal times.

2.Second: Premature beats may be asymptomatic, and palpitations or patronia may occur.

Frequent premature beats can cause symptoms such as fatigue and dizziness, which can induce or aggravate angina pectoris or heart failure in patients with pre-existing heart disease. Generally, if you go to the hospital for auscultation, you can hear it.

Thirdly, premature beats are not a serious disease, so patients should eliminate their worries, maintain emotional stability, and always maintain a cheerful mood, which is an important point in the care of premature cardiac beats. Avoid being overly excited or sad. Mood swings can easily induce premature contractions.

Precautions. So at this point, you can understand that the premature heart beat can be big or small, if you ignore him and let it develop, sooner or later there will be cardiac stagnation, and the result is conceivable.
