ECG Interpretation Tips and Clinical Takeaways

Practical ECG Interpretation Tips

• Use a Systematic Approach: Develop a consistent method for evaluating ECGs. A common approach includes assessing the rate, rhythm, P waves (presence, morphology, relationship to QRS), PR interval, QRS complex (width, morphology), and T waves.
• Treat the Patient, Not Just the Monitor: Always correlate ECG findings with the patient's clinical presentation. A rhythm on the monitor does not always accurately reflect the patient's true condition. For example, a patient may have a rapid heart rate on the monitor but be asymptomatic and hemodynamically stable.
• Continuous Monitoring: Continuous ECG monitoring is essential during resuscitation and post-resuscitation care to detect changes in rhythm and guide ongoing management.

Key Learning Points

• High-quality CPR is the most crucial intervention in non-shockable cardiac arrest (asystole and PEA).
• Rapid defibrillation is the single most effective intervention for VF and pVT.
• Pulseless Electrical Activity (PEA) is often caused by reversible factors (the H's and T's), and identifying and treating these factors is essential for successful resuscitation.
