This is often secondary to sinus tachycardia, sinus bradycardia and sinus arrhythmia, or isolated premature atrial or ventricular arrhythmias (VAs). The overall incidence of arrhythmia documented in pregnancy is reported to be in the range of 0.03%–0.5% of pregnancies,1 making this one of the most common cardiac complications of pregnancy, in women with and without structural heart disease.2–4 The incidence of arrhythmia in pregnancy is increasing, a rise attributable to the increase in the proportion of women with structural heart disease achieving successful pregnancies in the last decade.5 Clinical evaluation of the symptomatic pregnant patient begins with a careful history, detailing the timing of onset of symptoms, frequency and potential exacerbating factors.
