Episode 946: Time to Defibrillation

Quick background info

  • Cardiac arrest is when the heart stops pumping blood for any reason. This is different from a heart attack in which the heart is still working but the muscle itself is starting to die.

  • One cause of cardiac arrest is when the electrical signals are very disrupted in the heart and start following chaotic patterns such as Ventricular tachycardia (VTach) and Ventricular fibrillation (VFib)

  • One of the only ways to save a person whose heart is in VFib or VTach is to jolt the heart with electricity and terminate the dangerous arrhythmia.

A recent study in the Netherlands looked at how important the time delay is from when cardiac arrest is first identified to when a defibrillation shock from an Automated External Defibrillator (AED) is actually given.

  • Their main take-away: each minute defibrillation is delayed drops the survival rate by 6%!

  • These findings reinforce the importance of rapid AED deployment and early defibrillation strategies in prehospital cardiac arrest response.
