#### Example 1:
- **Graph Description**: This ECG strip spans 26 boxes horizontally.
- **Heart Rate**: 58 beats per minute.
- **Rhythm**: Irregular.
- **P Waves**: Shown.
- **QRS Complexes**: Narrow with a P-R Interval of 0.12 seconds.
- **Interpretation**: Sinus bradycardia with an AV block.
#### Example 2:
- **Graph Description**: This ECG strip spans 22 boxes horizontally.
- **Heart Rate**: 68 beats per minute.
- **Rhythm**: Regular.
- **P Waves**: None observed.
- **QRS Complexes**: Wide, with no measurable P-R Interval.
- **Interpretation**: Accelerated idioventricular rhythm (AIVR).
#### Example 3:
- **Graph Description**: This ECG strip spans 21 boxes horizontally.
- **Heart Rate**: Approximately 160 beats per minute.
- **Rhythm**: Irregular.
- **P Waves**: Shown, but wide.
- **QRS Complexes**: Narrow, with a P-R Interval of at least 0.16 seconds.
- **Interpretation**: Supraventricular tachycardia (SVT).
These examples provide insights into how to analyze and interpret various ECG readings. Understanding each component, such as heart rate, rhythm, presence and morphology of P waves, QRS complex width, and P-R interval duration, is crucial for accurate diagnosis and treatment.
