premature ventricular contractions
Introduction
Introduction Ventricular premature beats (or premature ventricular contractions), referred to as ventricular premature dysfunction, are clinically very common arrhythmias, which occur in a wide range of people, including normal healthy people and various heart disease patients. The clinical symptoms of ventricular premature beats are highly variable, ranging from asymptomatic, mild palpitations, to premature beats, triggering malignant ventricular arrhythmias, causing syncope or sputum, and there is no parallel relationship between clinical symptoms and prognosis. The clinical prognosis varies between normal healthy people and ventricular premature beats of various heart disease patients. Therefore, clinicians must be based on the patient itself when dealing with ventricular premature beats, that is, what kind of premature beats need to be treated, how to standardize treatment, and how to objectively evaluate the therapeutic effect is very important.
Cause
Cause
Ventricular premature beats can occur in normal people and various heart diseases. The chance of ventricular premature beats in normal people increases with age. Myocarditis, ischemia, hypoxia, anesthesia, surgery, and left ventricular false chordae can cause mechanical, electrical, and chemical stimulation of the myocardium to cause premature ventricular contractions. Digitalis, quinidine, and tricyclic antidepressant poisoning often precede the occurrence of severe arrhythmia with ventricular premature beats. Electrolyte disorders, mental disorders, excessive smoke, alcohol, and coffee can also induce ventricular premature beats. Ventricular premature beats are common in patients with coronary heart disease, cardiomyopathy, rheumatic heart disease and mitral valve prolapse.
Examine
an examination
The most common symptom of ventricular premature beats is palpitations. This is mainly due to the increase in heart rate after premature beats and the intermittent compensation after premature beats. Sometimes the patient feels like a slap in the front and a dizziness. The palpitations often cause anxiety in the patient, and anxiety can increase catecholamines and make ventricular premature beats more frequent, which creates a vicious circle. Symptoms of black and syncope can occur if ventricular premature beats trigger other tachyarrhythmias.
Diagnosis
Differential diagnosis
1, benign ventricular premature beats: refers to ventricular premature beats that can not find evidence of heart disease through various examinations, clinically very common. Benign ventricular premature beats will gradually increase with age, but it will not have much impact on health, so don't overburden your mind. Drinking a lot, smoking, drinking tea, coffee, anxious, nervous, and poor sleep can induce benign ventricular premature beats and should be avoided. Treatment can be used to stabilize 2.5mg, 3 times a day, when the heart rate is fast, it is best to use Betaloc 12.5 ~ 25mg, 2 times a day, mostly effective. You can also take a pack of Chinese medicine Wenxin granules, 3 times a day, the effect is not bad. It is not advisable to use too many antiarrhythmic drugs for benign ventricular premature beats to avoid more serious side effects.
2, prognostic ventricular premature beats: refers to the occurrence of ventricular premature beats based on organic heart disease, the most common heart disease is coronary heart disease and cardiomyopathy. You can check the echocardiogram, blood lipids, blood sugar, etc. If necessary, you can also check the electrocardiogram of the extreme plate exercise test to exclude coronary heart disease and cardiomyopathy. Prognostic ventricular premature beats should be administered and guided by a cardiologist. In addition to taking antiarrhythmic drugs, the following causes should be treated, such as myocardial ischemia, heart failure, hypokalemia, and hypomagnesemia.
