rhythm strips
**Understanding and Interpreting EKG Readings** An Electrocardiogram (EKG) is a test that records the electrical activity of the heart over a period of time. This guide will help you understand and interpret basic EKG readings. Below, you will find three different EKG strips with their associated parameters and interpretations. ### 1. EKG Strip 1 - **Rhythm:** Irregular - **Rate:** 100 beats per minute (bpm) - **P Waves:** Shown - **QRS Complexes:** - **P-R Interval:** 0.12 seconds - **Interpretation:** This EKG strip shows an irregular heart rhythm with a heart rate of 100 bpm. The P waves are present, and the P-R interval is within normal limits at 0.12 seconds. The interpretation section for this strip has been left blank, indicating that further analysis may be needed to determine the specific type of arrhythmia present. ### 2. EKG Strip 2 - **Rhythm:** Regular - **Rate:** 33 bpm - **P Waves:** - **QRS Complexes:** - **P-R Interval:** Not specified - **Interpretation:** This EKG strip shows a regular heart rhythm with a significantly low heart rate of 33 bpm. The interpretation notes “5 blocks PVC,” suggesting the presence of premature ventricular contractions (PVCs) occurring every five blocks. ### 3. EKG Strip 3 - **Rhythm:** Regular - **Rate:** 83 bpm - **P Waves:** Shown, some inverted - **QRS Complexes:** Narrow - **P-R Interval:** Not specified - **Interpretation:** This EKG strip shows a regular heart rhythm with a heart rate of 83 bpm. The P waves are present, but some are inverted. The QRS complexes are noted to be narrow, which is typically a positive sign indicating that the ventricles are depolarizing normally. ### Summary This guide illustrates common features and terminology used in EKG interpretation: - **Rhythm:** Determining whether the heart rhythm is regular or irregular - **Rate:** Calculating the heart rate in beats per minute - **P Waves:** Identifying the atrial depolarization - **QRS Complexes:** Observing ventricular depolarization - **P-R Interval:** Measuring the time between
