SINUS RHYTHMS

This video explains how to interpret normal sinus rhythm, sinus bradycardia, sinus tachycardia, sinus arrhythmia, and sinus pause/arrest in a step-wise approach. The RULES of EKG interpretation are applied to an example of each of one the sinus rhythms. Causes, signs and symptoms, and interventions are discussed, when applicable.

NORMAL SINUS RHYTHM:
1. Rate: 60-100 bpm
2. Regularity: regular
3. P- waves:
Upright
1 for every QRS complex
4. Intervals
PRI: 0.12-0.20 (3-5 boxes)
QRS: Less than 0.12 (3 boxes)

SINUS BRADYCARDIA:
(**indicates deviation from normal**)
**1. Rate: Less than 60 bpm
2. Regularity: regular
3. P- waves:
Upright
1 for every QRS complex
4. Intervals
PRI: 0.12-0.20 (3-5 boxes)
QRS: Less than 0.12 (3 boxes)

SINUS TACHYCARDIA:
(**indicates deviation from normal**)
**1. Rate: Greater than 100 bpm
2. Regularity: regular
3. P- waves:
Upright
1 for every QRS complex
4. Intervals
PRI: 0.12-0.20 (3-5 boxes)
QRS: Less than 0.12 (3 boxes)

SINUS ARRHYTHMIA:
(**indicates deviation from normal**)
1. Rate: 60-100 bpm, although may be brady- or tachycardic
**2. Regularity: irregular
3. P- waves:
Upright
1 for every QRS complex
4. Intervals
PRI: 0.12-0.20 (3-5 boxes)
QRS: Less than 0.12 (3 boxes)

I just finished this series and I am no longer intimidated of ECG interpretations. You break things down so well. Thank you for taking to your time to continue teaching us, Professor! <3
