What causes premature ventricular contractions?
Ventricular premature beats are the most common type of premature beats clinically, and they mostly occur in healthy people, also known as benign premature beats. They are caused by unstable autonomic nerve function leading to arrhythmia and do not require treatment with anti-arrhythmic drugs. Treatment through regulating nerves and lifestyle can lead to improvement. They can also occur in organic heart diseases, such as coronary heart disease, rheumatic heart disease, pulmonary heart disease, and viral myocarditis. These organic heart diseases, due to long-term myocardial damage, exhibit ectopic rhythms and require treatment with effective anti-arrhythmic drugs alongside treatment of the primary disease (the use of such drugs should be under the guidance of a physician).
