Appropriate clinical evaluation of ventricular ectopic beats is important to identify patients at risk for sinister arrhythmias and to target effective treatments like catheter ablation when necessary.
entricular ectopic beats (VEBs) are commonly seen in daily clinical practice. They are largely asymptomatic but can cause upsetting symptoms in some patients. In normal hearts, their occurrence is usually associated with no clinical significance. However, there are occasions where the presence of VEBs signifies a susceptibility towards more sinister arrhythmias, especially when heart disease is present. In some patients, VEBs are triggered by the same mechanism that gives rise to ventricular tachycardia which can be cured with catheter ablation. In addition, there are recent reports on the use of catheter ablation in cases where focal ventricular ectopics are found to trigger ventricular fibrillation. Appropriate clinical evaluation and investigations are important in assessing patients with VEBs so that effective treatment can be targeted when necessary. This article discusses the current knowledge and practice in this commonly encountered clinical cardiological problem.
