Paroxysmal cycle length shortening in the pulmonary veins during atrial fibrillation correlates with arrhythmogenic triggering foci in sinus rhythmDavid O'Donnell
Department of Academic Cardiology, Freeman Hospital, Newcastle upon Tyne, United Kingdom
J Cardiovasc Electrophysiol 13:124-8. 2002
..The focal origin of atrial fibrillation (AF) is identified by recording atrial ectopic beats or the ectopic activity that precedes AF. We hypothesized that arrhythmogenic pulmonary veins (PVs) also could be identified during persistent AF...

- How much training is required to implant and manage CRT?
David O'Donnell
Department of Cardiology, Austin Health, Heidleberg, Melbourne, Australia
Curr Opin Cardiol 27:29-35. 2012
..The implant, however, is not always performed effectively and the complication rates are considerable. The training and accreditation to perform CRT need to be evaluated to optimize procedural and patient outcomes...

Pacing Clin Electrophysiol 28:S24-6. 2005
..Individual changes could not be accurately predicted. The optimal stimulation parameters for CRT vary over time. Detailed, regular reevaluations, and reprogramming of optimal parameters may be appropriate...
