A fatal dysrhythmiaUsed interchangeably with arrhythmia, refers to any abnormal rhythm – not normal sinus rhythm or sinus tachycardia. 1. Six Second ECG Guidebook (2012), T Barill, p. 196 with rates usually less than 20/minute and common widening of the QRSThe 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...; also referred to as the dying heart.
AsystoleAbsence of electrical activity demonstrated by a straight ECG line. Most students of dysrhythmia courses arrive with the claim that they are at least skilled in recognizing asystole. In fact, most of us have seen the proverbial straight line on... is characterized by the absence of any waveforms. In reality, asystole is seldom a bone straight line until the patient has been without a pulse for some time. It is good practice to check lead integrity to ensure that the rhythmOften refers to a discernible pattern in time or distance between QRS complexes and/or P waves. seen is not another case of disconnected leads. Progress through all of the leads available through your cardiac monitor. Also, increase the gain or size to ensure that fine electrical activity is not present.
In the processA series of steps or actions taken to achieve a particular outcome, often repeatable and structured. A process is like a recipe, guiding each step to create a consistent result. towards asystole, the occasional occurrence of grossly wide and progressively irregular QRS complexes forms an agonal rhythm. The presence of an agonal rhythm is as serious as asystole, prompting many health care practitioners to consider stopping any further attempts at resuscitation.
