Mastering ECG Interpetation in Vet Med

Shockable Rhythms

  • Ventricular Fibrillation (VF): A chaotic heart rhythm that results in ineffective quivering of the ventricles, leading to loss of consciousness and absence of pulse.

  • Pulseless Ventricular Tachycardia (VT): A fast heart rhythm originating from the ventricles, which does not allow for effective pumping of blood.

  • Key Point: Only VF and pulseless VT are considered shockable rhythms; all other rhythms require medication for treatment.

CPR Protocol

  • Before delivering a shock, ensure proper CPR has been performed to maintain blood flow to vital organs.

  • CPR should be continued until the defibrillator is ready and a shock is delivered, or until emergency medical services (EMS) arrive.

Safety Protocols During Shock Administration

  • Team Communication: Clearly communicate within the team to ensure everyone is aware that a shock is about to be administered.

  • Clear the Area: Ensure personnel’s safety by advising everyone to step away from the patient to avoid accidental discharge of the defibrillator.

  • Monitor Equipment: Verify that all necessary equipment is functioning properly before providing a shock.

Post-Shock Care

  • After defibrillation, immediately resume CPR to circulate blood until the patient resumes a viable heart rhythm.

  • Administer appropriate post-resuscitation medications as indicated based on the rhythms and clinical guidelines.
