Key result
AV sequential pacing resolves pacemaker syndrome symptoms after ventricular pacing reduced ophthalmic pulse amplitude.
Why the study?
Pacemaker syndrome is characterized by symptoms such as vertigo, lightheadedness, syncope, and hypotension after ventricular pacemaker implantation, and non-invasive diagnostic methods were needed.

May link ventricular pacing to ocular hypoperfusion in pacemaker syndrome; leaves open OPG's intra-operative utility pending validation.
Miller et al. (1981) conducted a case report in Pacemaker syndrome (n=1). A-V sequential pacemaker vs. Ventricular pacing was evaluated on Symptoms of pacemaker syndrome and ophthalmic artery pulse amplitude. Implantation of an A-V sequential pacemaker eliminated all symptoms of pacemaker syndrome in a patient who demonstrated decreased ophthalmic artery pulse amplitude during ventricular pacing.
