The time taken to obtain diagnostic maps was measured together with the number of electrogram (EGM) points and accuracy compared to the arrhythmia diagnosis confirmed using a combination of map findings, entrainment, and response to ablation. In a subgroup of patients, concurrent contact mapping was performed with contact and SuperMap analysed by separate operators blinded to the other technique. The time taken to generate a diagnostic map, EGM number, and map accuracy was compared. Thirty-one patients (62 maps) were included with contact mapping performed in 19 [39 maps (33 for AT)]. SuperMap acquisition time was 314\u2009s [interquartile range (IQR) 239\u2013436]. The median number of EGM points used per map was 5399 (IQR 3279\u20138677). SuperMap was faster than contact mapping [394\u2009\u00b1\u2009219\u2009s vs. 611\u2009\u00b1\u2009331\u2009s; difference 217\u2009s, 95% confidence interval (CI) 116\u2013318, P\u2009&amp;lt;\u20090.0005]. The number of EGM points used per map was higher for SuperMap (7351\u2009\u00b1\u20095054 vs. 3620\u2009\u00b1\u20093211; difference 3731, 95% CI 2073\u20135388, P\u2009&amp;lt;\u20090.0005). SuperMap and contact mapping were accurate in 92% and 85% of maps, respectively, P\u2009=\u20090.4805.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n
