Abstract

Magnet waving was performed in a patient with a normally functioning, programmable, QRS-inhibited (VVI) pacemaker (Omni-Stanicor, Cordis Corporation), which was implanted for sick sinus syndrome. This procedure resulted in reversion to an asynchronous, nonsensing (irregular VOO) mode of operation with uneven stimulus-to-stimulus intervals. A short of ventricular tachycardia occurred when a stimulus fell on the T wave of the preceeding ectopic ventricular beat. This tachycardia was short-lived and was probably terminated by a single pacemaker stimulus. It is also suggested that magnet waving and external chest wall stimulation in patients with Omni-Ectocor and Starr-Edwards pacemakers require further study and that electrocardiograms recorded from patients in whom they have been implanted have to be analyzed taking into consideration that these pacemakers have features common to both, QRS-triggered (VVT), and QRS-inhibited (VVI) pacemakers.
