Commonly refers to the junctionConnects the atria to the ventricle and slows the impulse conduction speed sufficiently to allow for atrial kick; the junction consists of the AV node and the bundle of His; the junction is a supraventricular structure. 1. Six Second ECG...; for example, junctional rhythmA cardiac rhythm that occurs as a backup pacemaker when the sinus node fails to initiate an impulse; the junction typically fires at 40-60/minute; the P wave is either absent or inverted. A cardiac rhythm is usually named first by... is also known as nodal rhythmOften refers to a discernible pattern in time or distance between QRS complexes and/or P waves.; may also refer to the sinoatrial nodeLocated in the upper right atrium near the inlet for the superior vena cava, serves as the predominant pacemaker for the heart with rates usually of 60-100/minute. The SA node, usually the dominant pacemaker, is located in the right atrium....
