Multicenter Study Comparative Study
Correlation of intracardiac electrogram with surface electrocardiogram in Brugada syndrome patients.
The objective of this study was to correlate the electrocardiogram (ECG) modification during an Ajmaline challenge in patients affected by the Brugada syndrome and implanted with an implantable cardioverter-defibrillator (ICD) with the morphological changes of their ICD's intracardiac electrogram (IEGM). ⋯ In Brugada patients, ajmaline challenge elicits significant T wave amplitude changes within the ICD IEGM, greater than those of the IEGM ST segment. This study is the first step to provide new tools able to continuously monitor the type I Brugada aspect in patients affected by the Brugada syndrome.
