Disease relevance of Pre-Excitation Syndromes

• Electrophysiologic basis for the suppression by amiodarone of orthodromic supraventricular tachycardias complicating pre-excitation syndromes [1].
• We report a case of cardiac pre-excitation syndrome in a young male patient in whom amiodarone therapy (3000 mg/weekly) was instituted to modify the dangerous ventricular response during atrial fibrillation (shortest R-R interval 190 ms, ventricular rate 210 beats/min) [2].
• Evaluation of fetal heart rate artifacts, hemodynamics and digoxin treatment in fetal tachyarrhythmia by Doppler measurement of fetal blood flow--case report of a pre-excitation syndrome [3].

High impact information on Pre-Excitation Syndromes

• Mitochondrial DNA causal for LHON may contribute to pre-excitation syndrome [4].
• Electrophysiological and electropharmacological studies in pre-excitation syndromes: results with propafenone therapy and isoproterenol infusion testing [5].
• Pre-excitation syndrome and hypertrophic cardiomyopathy [6].
• Evaluation of verapamil in the management of pre-excitation syndrome [7].
• Atropine in pre-excitation syndrome [8].

Anatomical context of Pre-Excitation Syndromes

• Digoxin may be administered in all forms of supraventricular tachycardia in which the atrioventricular node is involved, except in patients with pre-excitation syndrome aged >1 year [9].
