Five cases of benign fetal arrhythmias presented with dramatic pictures of sustained irregular bradycardias. These cases were not associated with structural heart disease, the development of hydrops fetalis, or maternal autoantibodies. In all but one case, the arrhythmias resolved before delivery. Two fetuses had 2:1 atrioventricular block and the other three showed group beating due to blocked atrial trigeminy. With regular intermittent reevaluation, and if no signs of hydrops occur, watchful waiting is the suggested therapeutic modality.

Ventricular ectopics, also known as ventricular extrasystoles, premature ventricular contractions or complexes (PVC) and ventricular premature depolarisations (VPD) are beats arising from within the ventricles. When they occur in groupings such as bigeminy, trigeminy, couplets and triplets they are referred to as ventricular ectopy. The electrocardiographic (ECG) footprints of a ventricular ectopic include a broad (>110 ms), premature, ventricular complex (QRS deflection); no evidence of pure atrioventricular (AV) conduction; a full, more than, or less than compensatory pause; and discordant QRS and T wave axis. Ventricular ectopy is a very common finding on Holter monitoring at all ages, but particularly in the elderly. In the otherwise normal heart, ventricular ectopy is generally infrequent and a benign finding, but in patients with heart disease, they may be a harbinger to more serious ventricular tachyarrhythmias. In this review, the range and manifestations of ventricular ectopy will be explored in detail with ECG examples.
