This report describes a patient who presented with transient central nervous system symptoms of unknown etiology with an electrocardiogram exhibiting a narrow QRS complex and normal P‐R interval. The decision to implant a permanent VVI pacemaker was made on the basis of a His bundle study that revealed significant prolongation of the HV interval. The successful clinical outcome re‐emphasizes the clinical usefulness of electrophysiologicol investigation in patients with syncope of undetermined etiology.
