ACLS Rhythm Strips – FAQ

What are ACLS rhythm strips?

ACLS rhythm strips are electrocardiogram (ECG) tracings used in Advanced Cardiovascular Life Support (ACLS) to identify various heart rhythms. These strips help medical professionals determine the appropriate treatment for patients experiencing cardiac events such as arrhythmias, heart attacks, or other serious heart conditions.
