Atrial trigeminy was seen in a patient with a normally functioning DVI pacemaker (Byrel‐5992). Atrial competition resulted from coincidence of sinus and atrial escape rates together with late ventricular sensing. This resulted in atrial output stimuli occurring within the QRS complex. Alternate impulses occurred late enough to conduct to the ventricle after recovery of tbe AV node. Reprogramming the pacemaker to either a faster DVI rate or to VVI abolished the arrhythmia.
