Frequent Ventricular Ectopics in a Healthy Adult Woman - is it Associated with Sudden Cardiac Death?

The prevalence of ventricular arrhythmia in the general population vary widely depending on the method of detection, age groups and underlying heart disease: from as low as 0.8% in healthy military population recorded on 12-lead ECG (0.5% in those <20 years, 2.2.% in those >50 years), to 62% in middleaged adults (a mix of those with or without known heart disease) using 6-hour monitoring.[1] A survey of patients attending Dutch general practice clinics for palpitation, 28.2% had documented arrhythmia by ECG, about one-third of these were ventricular ectopic (10.6%).[2]
