Frequent multiple source premature ventricular beats, sometimes in pairs, are 2 consecutive premature ventricular beats found together on the ECG. Frequent multigenic premature ventricular beats mean that there are many premature ventricular beats, frequent episodes, and although they originate from the ventricles, they are from different abnormal pacing points within the ventricles, and so there is a difference in the morphology of the premature ventricular beats, sometimes in pairs, which refers to 2 consecutive premature ventricular beats together. Frequent multiple ventricular premature beats sometimes in pairs suggests the possibility of ventricular tachycardia malignant arrhythmia. 24-hour ambulatory electrocardiogram and cardiac ultrasound need to be examined to clarify the patient’s condition and cardiac diseases such as cardiomyopathy and heart failure. If so, they are prone to malignant arrhythmia and need further systematic treatment in a timely manner, which requires specialized cardiologists to guide the treatment. Found that frequent multiple sources of premature ventricular beats sometimes in pairs, need to consult the cardiology department in a timely manner, to clarify the condition of the systematic treatment.
