The patient is pulseless and rapidly loses consciousness and stops breathing. These rhythms do not revert spontaneously. This condition causes cardiac arrest. Chest x-ray: may show evidence of congestive heart failure. Also, evidence of the underlying cardiac pathology may be seen such as ventricular enlargement.

Blood tests should exclude electrolyte imbalances. Cardiac enzymes should be tested to establish whether an acute heart attack has occurred. The prognosis of these arrhythmias is generally poor. Amiodarone, lidocaine, and magnesium are antiarrhythmic medications that are used in the left branch of the Cardiac Arrest Algorithm. These medications were be reviewed in more detail in the previous lesson. Jeff, Thanks for the site.

Profile Page. Cardiac Arrest Algorithm Diagram. Many of the patients that experience sudden cardiac arrest demonstrate VF at some point in their arrest, therefore, training emphasis is placed on the cardiac arrest algorithm. There are several important points that should be considered when initiating the cardiac arrest algorithm: High-quality CPR should be performed until the defibrillator is attached the patient. Interruptions in chest compressions should be kept to a minimum.

Rapid use of the defibrillator should be emphasized. This is highly recommended reading for all. Pellegrini, C. Curr Probl Cardiol. Review article for Vtach. Marill, K. Crit Care Med. Tzivoni, D.
