Frequent ventricular premature beats are premature heart beats that originate in the ventricles and have a frequency greater than or equal to 6 beats per minute. Ventricular premature beats are the most common type of premature beats that occur in the ventricles in the midst of regular heartbeats. The frequency of premature ventricular contractions can be divided into episodic contractions of less than 5 beats per minute and frequent contractions of 6 beats per minute or more. Frequent premature ventricular contractions occur in patients with underlying heart disease such as coronary artery disease, hypertensive heart disease, and structural changes in the heart due to heart valve disease, but they can also occur in some healthy people. Symptoms of frequent premature ventricular contractions may include panic attacks, chest tightness, cardiac arrest, and weakness, and in severe cases, blackness or syncope. Patients with underlying cardiac disease may have frequent premature ventricular contractions that exacerbate the symptoms of their existing disease. Some patients with other types of ventricular arrhythmias at the site of origin are at risk for sudden cardiac death. In addition, frequent premature ventricular contractions may lead to insufficient blood supply to the heart, brain, kidneys and other important organs, causing chest tightness, palpitations, dizziness and weakness; long-term frequent premature ventricular contractions may lead to structural and functional changes of the heart, resulting in heart failure. The severity of frequent premature ventricular contractions does not correlate with the patient’s subjective symptoms. When frequent premature ventricular contractions are detected, it is important to consult a doctor in time and choose medication or radiofrequency ablation surgery according to the professional doctor’s guidance. Frequent premature ventricular contractions are one of the types of premature contractions and should be treated promptly regardless of whether they are symptomatic or not.
