Premature ventricular beats are those in which the rhythm transmitted from any of the ventricles or septum precedes the rhythm transmitted from the sinus node and sends an impulse ahead of time and causes the heart to beat. What are the signs of premature ventricular contractions? Individuals vary considerably, with some experiencing no discomfort. Some people may feel panic attacks and their heart goes “boom boom”. Severe premature ventricular contractions can lead to dizziness and fainting. What is the risk of premature ventricular contractions? The prognosis of premature ventricular contractions depends on the type of contraction, whether it triggers a tachyarrhythmia, and whether the patient has organic heart disease. Therefore, the prognosis is different in different populations. In individuals without heart disease, most premature ventricular beats are due to functional factors and have a good prognosis. However, in people with frequent premature ventricular beats caused by heart disease, they often indicate a poor prognosis and an increased risk of sudden death. What tests are needed to detect premature ventricular contractions? Electrocardiogram (ECG), ambulatory electrocardiogram (ECG), cardiac ultrasound, and platelet exercise test are commonly used. If ventricular premature beats are frequent, electrophysiologic examination is necessary to understand the number and pattern of premature beats, the structure of the heart, cardiac function, and the site of origin of the premature beats, which will help to determine the severity of the premature beats and to decide on a further treatment plan. If it is caused by coronary ischemia, coronary angiography is needed. As the stenosis of the blood vessels is relieved or lifted, most of the premature ventricular beats can be relieved or disappear. Do all premature ventricular beats require treatment? Premature ventricular contractions that are not caused by underlying heart disease are very common and do not require any special treatment. However, it is important to avoid drinking a lot of alcohol, smoking, strong tea and coffee. However, if ventricular premature beats occur frequently and cause obvious symptoms that affect your life, you can use beta-blockers, mexiletine own proprietary Chinese medicines, such as stabilizing the heart granules, ginseng pine heart capsules and so on. For non-organic ventricular premature beats, when the 24-hour dynamic electrocardiogram suggests that the number of premature beats is more than 10,000 times, and the load of premature beats is more than 10-20%, with the prolongation of time, heart enlargement, cardiac insufficiency, ventricular premature cardiomyopathy, which needs active treatment. For ventricular premature beats with organic heart disease, it is more important to pay great attention. Drugs or radiofrequency ablation therapy should be given under the guidance of a physician. In conclusion, if ventricular premature beats are detected, don’t be too nervous, just go to the regular hospital for treatment, and let the cardiovascular specialist to evaluate whether active treatment is needed.
