EKG Interpretation (HCA) Answered 100% Correctly 2024/2025 Atrial Rhythms • Are not classic “P-wave” rhythms, if equal/consistent/nonvarying P-waves are easily identified then the rhythm is NOT atrial in origin • Atrial rhythms are routinely fast • Ventricular rates can be controlled (<100) or uncontrolled (>100) • Ventricular responses and rates can reach up to 220 – 240 ppm • Ventricular regularity can be regular or irregular, depending on the rhythm: - AFib, WAP & MAT = ALWAYS IRREGULAR - Aflutter = Regular or Irregular - SVT/PSVT, ATach = ALWAYS REGULAR • QRS-complexes can be Narrow (<0.12 sec) or Wide (>0.12 sec). This is measured using the ECG paper (<0.12 = less than 3 small boxes; <0.12 = greater than 3 small boxes) Atrial Rhythms & Associated Rates
