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.
