2022年4月30日 · An agonal rhythm is an abnormally slow, erratic rhythm originating from your heart’s lower chambers (ventricles). This type of severe arrhythmia occurs after your heart’s upper chambers have stopped working.

In medicine, an agonal heart rhythm is a variant of asystole. Agonal heart rhythm is usually ventricular in origin. Occasional P waves and QRS complexes can be seen on the electrocardiogram. The complexes tend to be wide and bizarre in morphological appearance. [1] .

2021年11月8日 · Agonal rhythm is often the last ordered semblance of organized electrical activity in the heart prior to death. Heart rate is less than 20 bpm, without P waves and a wide, bizarre QRS complex. The rate is often so slow, that on a singular six-second rhythm strip it will be impossible to determine whether the rhythm is regular or irregular.

2023年11月4日 · Agonal Rhythm is a slow and irregular electrical cardiac activity observed in the dying stages, often associated with impending cardiac arrest.

QRS complexes may be narrow or wide in PEA, and the heart rate can be very slow (agonal rhythm), normal, fast, regular or irregular. The ventricular rate (assessed on the ECG) in PEA usually does not exceed 130 beats/min and it is not possible to defibrillate PEA.

2024年9月24日 · Agonal heart rhythm refers to electrical activity recorded on an electrocardiogram (ECG) during the final stages of life. It can take various forms, including terminal rhythm, asystole, or agonal bursts. These rhythms often occur in association with physiological indicators such as agonizing respiratory gasping, agonal delirium, and …

2024年9月9日 · Explore the key differences between agonal rhythm and idioventricular rhythm, two critical cardiac arrhythmias that require prompt recognition and appropriate management in clinical settings.

2013年11月12日 · It shows an idioventricular escape rhythm, with very wide QRS complexes and only two complexes in six seconds. (The top arrows mark three-second segments.) If you look closely at the points marked by the lower arrows, you will see small, uniform, regular P waves. The mechanism leading to this agonal rhythm was complete heart block.

2021年11月8日 · Agonal rhythm is often the last ordered semblance of organized electrical activity in the heart prior to death. Heart rate is less than 20 bpm, without P waves and a wide, bizarre QRS complex. The rate is often so slow, that on a singular six-second rhythm strip it will be impossible to determine whether the rhythm is regular or irregular.

2016年11月14日 · An agonal heart rhythm is a variant of asystole with a heart rate is less than 20 bpm, without P waves and with wide, bizarre QRS complexes seen on the electrocardiogram. Clinically, an agonal rhythm is regarded as asystole and should be treated equivalently, with cardiopulmonary resuscitation.
