Heyyo guys!!
Want to quickly understand ECG strips? Here’s a summary to get you started:
1. **The Basics**
- Each ECG strip records 6 seconds.
- Large box = 0.2 seconds (5 small boxes).
- Small box = 0.04 seconds.
2. **Heart Rate Calculation**
- **Quick Method:** Count R waves in 6 seconds, then multiply by 10.
- **Precise Method:** Count small boxes between two R waves and divide 1500 by that number.
3. **Interpreting Rhythm**
- Check if R wave intervals are consistent (regular rhythm).
- Use “marching out” to measure distance between R waves across the strip.
Understanding these basics will boost your confidence in reading ECGs. Stay curious and keep learning!
