WebSinus rhythm. Schematic representation of normal sinus rhythm showing standard wave, segments, and intervals. A sinus rhythm is any cardiac rhythm in which depolarisation of the cardiac muscle begins at the sinus node. [1] It is characterised by the presence of correctly oriented P waves on the electrocardiogram (ECG). [2] WebIn 2005 Viskin and colleagues performed a study among 877 physicians worldwide and asked them to determine the QT interval on 4 rather straightforward ECGs (i.e. with concordant T-waves of sufficient amplitude during regular sinus rhythm) and to classify these QT intervals as either normal or prolonged.
