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] WebSchematic representation of a normal sinus rhythm EKG wave In electrocardiography , the PR interval is the period, measured in milliseconds, that extends from the beginning of the P wave (the onset of atrial depolarization ) until the beginning of the QRS complex (the onset of ventricular depolarization); it is normally between 120 and 200 ms in duration. im the celebrity
