Distribution and prognostic significance of QT intervals in the lowest half centile in 12,012 apparently healthy personsMark Michael Gallagher
Department of Cardiology, University of Rome Tor Vergata, Rome, Italy
Am J Cardiol 98:933-5. 2006
..In conclusion, a QTc interval of <or=330 ms is extremely rare in healthy subjects, and the presence of a QT interval in the lowest 1/2 centile of the normal range does not imply a significant risk of sudden death...
- Arrhythmic complications of electrical cardioversion: relationship to shock energy
Mark M Gallagher
Department of Cardiological Sciences, St George s Hospital Medical School, Cranmer Terrace, London SW17 0RE, UK
Int J Cardiol 123:307-12. 2008
..We hypothesised that more powerful shocks would exceed the upper limit of vulnerability for inducing ventricular fibrillation. The initial use of higher energy could therefore reduce arrhythmic complications...
- Feasibility and safety of a simplified draping method for pacing procedures

Europace 9:890-3. 2007
..Traditional draping for pacing procedures is time-consuming. We evaluated prospectively the safety of a simplified method using a single adhesive drape intended for use in cardiac catheterization...
Ventricular pauses during atrial fibrillation predict relapse after electrical cardioversion: a prospective studyMark Michael Gallagher
Division of Cardiac and Vascular Sciences, St George s Hospital, University of London, London, United Kingdom
Pacing Clin Electrophysiol 33:934-8. 2010
..To investigate the use of ambulatory electrocardiogram (ECG) monitoring in atrial fibrillation (AF) to predict recurrence after electrical cardioversion (ECV)...
- Prevalence and significance of Brugada-type ECG in 12,012 apparently healthy European subjects

Department of Cardiology, University of Rome Tor Vergata, Viale Oxford 81, 00197 Rome, Italy
Int J Cardiol 130:44-8. 2008
..The prevalence of the Brugada-type ECG and its natural history are still unclear. The recently proposed diagnostic criteria have not been systematically applied in a European general population...
- Electrocardiographic markers of structural heart disease and predictors of death in 2332 unselected patients undergoing outpatient Holter recording
Mark M Gallagher
Department of Cardiology, Policlinico Tor Vergata, Viale Oxford 81, Rome 00133, Italy
Europace 9:1203-8. 2007
..To test the hypothesis that the QS interval of ventricular ectopic beats (VEBs) (ventricular ectopic QS interval, VEQSI) would provide a marker for the presence of structural heart disease and a predictor of mortality...
- Initial energy setting, outcome and efficiency in direct current cardioversion of atrial fibrillation and flutter
M M Gallagher
Department of Cardiological Sciences, St George s Hospital Medical School, London, United Kingdom
J Am Coll Cardiol 38:1498-504. 2001
..The purpose of this study was to design a more efficient protocol for the electrical cardioversion of atrial arrhythmias...
- Changes in brain natriuretic peptide level as a predictor of AF recurrence after electrical cardioversion
F Ruggiero
Department of Cardiology, Tor Vergata University, Rome, Italy
Minerva Cardioangiol 59:135-8. 2011
..Accurate prediction of AF recurrence might allow more selective use of ECV and the targeted use of antiarrhtyhmic therapy in those at highest risk of recurrence...

..0028) and created a significant difference between the two slopes (P = 0.0004). The evolution of P-SAECG parameters after ECV differs in patients whose AF recurs versus patients who remain in SR...
- Tachycardia-induced atrial myopathy: an important mechanism in the pathophysiology of atrial fibrillation?
M M Gallagher
