Frequent premature heart beats, especially ventricular premature beats, first cause symptoms associated with the patient, symptoms of palpitations and dizziness. Long-term frequent ventricular premature beats, usually the frequency of ventricular premature beats per hour is more than 30 times, or the number of episodes per day in 24 hours is more than 10,000 times, especially if you do a 24-hour ambulatory electrocardiogram, found that ventricular premature beats accounted for more than 15% of the number of beats of the whole day in 24 hours, and the long-term persistence of this situation will cause the heart to enlarge, the decline of cardiac function, and the tube of this situation is called premature ventricular This condition is called premature ventricular cardiomyopathy. Once this condition occurs, the only way to treat it is to completely eliminate the premature ventricular beats, so that the heart function can be improved. Therefore, if there are frequent episodes of premature ventricular disease and related symptoms, it is recommended that the patient undergo a 24-hour ambulatory electrocardiogram and cardiac ultrasound to see if the premature ventricular disease has 10,000 episodes per day or exceeds more than 15 percent of the total heartbeats in the whole 24-hour day. If this is the case and there are associated symptoms, the first step is to administer symptomatic medication. If medication is not effective, radiofrequency ablation may be considered to reduce the ventricular prematureness, to prevent or reverse the likelihood of ventricular premature cardiomyopathy, and to improve the patient’s symptoms and prognosis.
