- Title
Ventricular Fibrillation Following Elective Cardioversion in a Patient with Permanent Pacemaker.
- Authors
Vera, Zakauddin; Bommer, William J.; Desai, Jawahar M.
- Abstract
Elective cardioversion was undertaken in a patient with a VVI pacemaker and atrial tachyarrhythmia after converting the pacemaker to a VOO mode of function. The cardioverter output energy was unwittingly synchronized to the pacemaker output pulses that were falling randomly in various portions of the cardiac cycle. This resumed in the cardioverter DC shock being discharged in the ST segment of the native QRS with consequent ventricular fibrillation.
