What is agonal rhythm?

Agonal rhythm, also known as agonal heart rhythm or agonal pulse, is a type of abnormal heart rhythm that occurs in the final stages of life or during a life-threatening emergency. It is characterized by irregular and often slow heartbeats that are insufficient to sustain normal circulation. Agonal rhythm can be seen on an electrocardiogram (ECG) as wide and bizarre QRS complexes with variable intervals between beats.

Agonal rhythm is typically associated with severe cardiac dysfunction, such as myocardial infarction, heart failure, or sudden cardiac arrest. It may also occur in patients who are in the process of dying due to terminal illnesses, severe trauma, or other critical conditions.

Because agonal rhythm is a sign of profound cardiac compromise, it is considered a medical emergency that requires immediate intervention. Cardiopulmonary resuscitation (CPR) and the administration of advanced cardiac life support (ACLS) medications are often needed to restore normal heart function and improve the chances of survival.

Overall, agonal rhythm is a serious and potentially life-threatening condition that requires prompt attention and appropriate medical management to prevent further complications and improve outcomes.
