The EKG Rhythm Interpretation Badge Card is a compact study and clinical reference for student adults learning ECG rhythm interpretation. The front presents color grouped rhythm strips with labels and key traits, including shockable rhythms, non shockable rhythms, and cardioversion indicated patterns to support rapid review. The back covers core measurement skills: PR, QRS, and QT interval meanings, normal ranges, and critical thresholds, plus ECG box timing references with visual alignment guidance. A built in R to R heart rate scale supports fast rate estimates at standard ECG speed. Sized 3.54 x 5.12 inches, this durable plastic badge card fits most badge holders and pockets, wipes clean, and stays easy to read on the go. Add it to your nursing telemetry kit, EMT training tools, or exam prep materials for quick practice anywhere. This product is intended as an educational reference tool only and does not replace clinical judgment or patient assessment.
