A fast rhythmOften refers to a discernible pattern in time or distance between QRS complexes and/or P waves. with rates commonly 150-240/minute; QRS complexThe electrical representation of ventricular depolarization; the atrial repolarization is also a part of the QRS. ECG interpretation relies heavily on the QRS complex. The QRS complex represents the depolarization of the ventricles. The repolarization of the atria is also... is most often narrow; rhythm is usually generated from a re-entryOne of several causes of dysrhythmias, the re-entry loop often results in tachycardias; the re-entry loop requires an area with slowed speed of conduction, an proximal area with regular conduction speed and cells that are receptive to depolarizing; the loop... loop – often making use of an accessory bundle and the AV nodeIs located in the inferior aspect of the right atria; functions to slow the conduction speed to allow for atrial conduction prior to ventricular conduction (atrial kick); also serves as a pacemaker if the SA node fails to fire.
