This chapter covers the incidence, etiology, and treatment of the most common electrocardiogram and rhythm disturbances encountered during pregnancy. Baseline electrocardiogram changes associated with pregnancy include left ventricular hypertrophy and ST segment depressions secondary to anatomic and metabolic changes of pregnancy. The most common arrhythmias include atrial and ventricular ectopy, which are usually benign in nature. Supraventricular and ventricular tachycardia are also discussed in detail, along with the impact of antiarrhythmic and electrical conversion therapy on fetal and maternal well-being. An understanding of the pathophysiology, assessment, and treatment of these rhythm disturbances is requisite knowledge for all anesthesiologists to provide optimal and timely care to parturients.
