ABSTRACT
INTRODUCTION Rhythm disturbances are common in the general population. Indeed, atrial fibrillation (AF), the most widespread arrhythmia, has an overall prevalence of 1%, rising with age, affecting nearly 10% of those aged over 80 years (1-3). Another 0.2% to 0.8% of people have experienced an episode of supraventricular tachycardia (SVT) at some point in their lives (4,5) and 3% of the population have had a myocardial infarction in the past (6), providing a potential substrate for ventricular arrhythmias.
