CLINICAL RESEARCH A new electrocardiogram algorithm for diagnosing loss of ventricular capture during cardiac resynchronisation therapy Vincent Ganie ` re 1,2, Giulia Domenichini 1, Viviana Niculescu 1, Romain Cassagneau 2 , Pascal Defaye 2, and Haran Burri 1 * 1Cardiology Department, University Hospital of Geneva, Geneva, Switzerland; and 2Cardiology Department, University Hospital of Grenoble, Grenoble, France Received 7 July 2012; accepted after revision 4 September 2012 Aims The prerequisite for cardiac resynchronization therapy (CRT) is ventricular capture, which may be veri?ed by analysis of the surface electrocardiogram (ECG). Few algorithms exist to diagnose loss of ventricular capture. Methods and results Electrocardiograms from 126 CRT patients were analysed during biventricular (BV), right ventricular (RV), and left ventricular
