In PALS, how is shockable rhythm identified?

In Pediatric Advanced Life Support (PALS), shockable rhythms are specifically identified as either ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT). These two rhythms are significant because they indicate a heart that is not effectively pumping blood, and defibrillation is most likely to restore a normal rhythm in these situations.

When ventricular fibrillation occurs, the heart's electrical activity becomes chaotic, preventing effective contraction and blood circulation. Similarly, pulseless ventricular tachycardia is characterized by a rapid heart rhythm that does not allow the heart chambers to fill adequately with blood, leading to a lack of effective cardiac output.

Defibrillation is the recommended intervention for these shockable rhythms, as it delivers a synchronized electrical shock to the heart, potentially allowing it to revert to a normal rhythm. This critical distinction defines the importance of identifying these rhythms during resuscitation efforts in pediatric patients. Recognizing these types of rhythms promptly is vital for effective treatment and successful outcomes in cardiac arrest situations.
