Having a hard time interpretting this study strip

**ECG Analysis Worksheet**

---

**ECG Strip:**

The image above displays an electrocardiogram (ECG) strip. This strip is used to analyze the electrical activity of the heart, providing insights into heart rate, rhythm, and conduction pathways.

**Observation and Interpretation Table:**

| **Observation** | **Interpretation** |
|-----------------|--------------------|
| 1. What is the Heart Rate? | |
| 2. What is the rhythm? Regular or Irregular? | |
| 3. How is atrial activity related to ventricular activity? Is there a P wave before each QRS? | |
| 4. Are P waves upright and uniform? | |
| 5. What is the length of the PR interval? | |
| 6. Do all QRS complexes look alike? | |
| 7. What is the length of the QRS complexes? | |

**Diagnosis:**

*The section for diagnosis is highlighted in yellow.* 

**Graph/Diagram Explanation:**

The ECG strip at the top showcases a series of waves representing one cardiac cycle. The major components—P wave, QRS complex, and T wave—are essential for diagnosing various heart conditions. Each small square on the graph typically represents 0.04 seconds, and five small squares make up a large square (0.20 seconds).

- **P wave:** Represents atrial depolarization.
- **QRS complex:** Reflects ventricular depolarization.
- **T wave:** Indicates ventricular repolarization.

Interpreting these elements helps in evaluating heart function and identifying any abnormalities.
