### ECG Interpretation Guide

#### Sample #1
<img src="sample1-ecg.png" alt="ECG Example 1">

- **Rhythm:** Regular
- **Rate:** 50 bpm
- **P Waves:** Shown upright
- **QRS Complex:** Narrow
- **P-R Interval:** 0.16 seconds
- **Interpretation:** Sinus Bradycardia

#### Sample #2
<img src="sample2-ecg.png" alt="ECG Example 2">

- **Rhythm:** Irregular
- **Rate:** 120 bpm
- **P Waves:** None
- **QRS Complex:** Narrow
- **P-R Interval:** None
- **Interpretation:** (Incomplete, likely a form of tachycardia based on the given data)

#### Sample #3
<img src="sample3-ecg.png" alt="ECG Example 3">

- **Rhythm:** Irregular
- **Rate:** 31 bpm
- **P Waves:** None
- **QRS Complex:** Narrow
- **P-R Interval:** None
- **Interpretation:** Junctional Bradycardia

### Explanation of Terms
- **Rhythm:** Refers to the regularity of the heartbeats.
- **Rate:** The number of heartbeats per minute.
- **P Waves:** Corresponds to atrial depolarization.
- **QRS Complex:** Represents the depolarization of the right and left ventricles.
- **P-R Interval:** The period, measured in seconds, that starts at the beginning of the P wave and ends at the beginning of the QRS complex.
- **Sinus Bradycardia:** A slower than normal heart rate, originating from the sinus node.
- **Junctional Bradycardia:** A slower than normal heart rate due to the initiation of impulses by tissue located around the AV junction rather than the SA node.
