Cardiologists separately analysed 12-lead ECGs and the smartwatch ECGs taken from the left wrist (AW-I) and then from chest positions V1, V3, and V6 (AW-4). Compared with AW-I, AW-4 improved the classification of ECGs as \u2018abnormal\u2019, increasing the sensitivity from 64% to 89% (P\u2009&amp;lt;\u20090.01). Pre-excitation was detected in most cases using AW-I (sensitivity 89%) and in all cases using AW-4 (sensitivity 100%, P = 0.48 compared with AW-I, specificity 100% for both). Brugada was missed using AW-I but was detected in 11\/12 patients using AW-4 (sensitivity 92%, specificity 100%, P = 0.003). Long QT was detected in 8\/10 cases using AW-I (sensitivity 80%, specificity 100%) and in 9 patients using AW-4 (sensitivity 90%, specificity 100%, P &amp;gt; 0.99). Hypertrophic cardiomyopathy was correctly suspected using AW-I and AW-4 (sensitivity 92% and 85%, specificity 85%, and 100%, P &amp;gt; 0.99). AW-I was mostly (62%) considered normal in ARVC\/D whereas AW-4 was useful in suspecting ARVC\/D (100% sensitivity, 99% specificity, P = 0.004).<\/jats:p>\n               <\/jats:sec>\n
