ECG Rhythm Identification
ECG Strip 37: Atrial Fibrillation (A-Fib)
Key Features:
- Irregularly irregular rhythm
- Absence of distinct P waves
- Irregular R-R intervals
Clinical Significance: Can lead to decreased cardiac output and thromboembolism risk. Requires
rate control or anticoagulation.
ECG Strip 38: Supraventricular Tachycardia (SVT)
Key Features:
- Narrow QRS complexes
- Very fast rate (~150-250 bpm)
- P waves may be hidden in T waves
Clinical Significance: Causes palpitations, hypotension. Treated with vagal maneuvers, adenosine,
or cardioversion.
ECG Strip 39: Premature Ventricular Contraction (PVC)
Key Features:
- Wide and bizarre QRS complex
- Occurs early without a preceding P wave
- Followed by a compensatory pause
Clinical Significance: May be benign or indicate underlying issues like hypoxia or electrolyte
imbalance.
ECG Strip 40: Normal Sinus Rhythm (NSR)
