| + | The 12-lead resting ECG measures electrical activity of the heart during rest, summarized in 12 leads.\\ | ||
| The ECG provides many (>400) different variables at once, both quantitative and qualitative traits. These include duration, voltage and configuration characteristics. For example, information is provided of the cardiac rhythm, heart rate, the function of the sinoatrial and the atrioventricular node, atrial size, left ventricular mass, and repolarisation time (e.g. QT time). | The ECG provides many (>400) different variables at once, both quantitative and qualitative traits.
