Premature ventricular contractions of up to 14,000 beats in twenty-four hours are considered to be frequent ventricular premature beats, and are harmful. Premature ventricular contractions of up to 14,000 beats in twenty-four hours are a relatively common type of arrhythmia, the pathogenesis of which is due to abnormal electrical activity in the ventricular muscle, which causes premature agitation of this part of the heart muscle and leads to contraction of other ventricular muscles. It may result in insufficient blood supply to the heart to provide nutrients to vital organs throughout the body and can be treated with radiofrequency ablation. Radiofrequency ablation of the heart is a procedure that involves spot-calibration within the heart to find abnormally excited heart muscle, and the use of heat to physically damage that part of the heart muscle so that it no longer becomes abnormally excited. Some patients with milder symptoms or fewer episodes of premature beats may be able to reduce or not have episodes by eating a light diet, quitting smoking, avoiding late nights, or using medications such as metoprolol tablets and bisoprolol. All of the above medications should be used under the guidance of a professional doctor to avoid adverse reactions from self-medication.
