Identifying Normal Sinus Rhythm on ECG in Cardiology
Normal sinus rhythm on ECG is defined by a set of formal criteria describing the conduction sequence from atrium to ventricle: each QRS complex must be preceded by a P wave, each P wave must be followed by a QRS complex without conduction blockage, and the P waves must be morphologically identical, upright in leads II and aVF, and of normal (non-prolonged) duration. This concept belongs to the domain of cardiac electrophysiology and ECG interpretation, where deviation from any of these criteria indicates the presence of an arrhythmia.
