Examples
By Part of Speech
verb
British English
- The paramedics had to defibrillate the casualty at the scene.
- We may need to defibrillate if the rhythm deteriorates to VF.
American English
- The doctor ordered the team to defibrillate the patient immediately.
- The AED is designed to analyze the rhythm and defibrillate if necessary.
adjective
British English
- The defibrillated heart resumed a normal sinus rhythm.
- A successfully defibrillated patient still requires urgent hospital care.
American English
- The defibrillated patient was stabilized for transport.
- Post-defibrillated care is critical.
Examples
By CEFR Level
- A special machine can help a stopped heart. This is very important.
- In an emergency, doctors sometimes use electric shocks on the heart.
- If a patient goes into cardiac arrest, the medical team may need to defibrillate them quickly.
- The protocol mandates that first responders defibrillate as soon as possible when presented with a shockable rhythm like ventricular fibrillation.
Learning
Memory Aids
Mnemonic
Think: DE-FIBRILL-ATE: DE (to remove) + FIBRILL (from 'fibrillation', the quivering) + ATE (verb ending). You remove the fibrillation.
Conceptual Metaphor
THE HEART IS A MACHINE that can be 'restarted' with a 'jump' of electricity.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'дефибрировать' (a less common variant). The standard term is 'дефибриллировать'.
- Avoid calquing the English structure as 'делать дефибрилляцию'; the correct verb is 'дефибриллировать'.
Common Mistakes
- Misspelling: 'defibrilate' (missing one 'l'), 'deffibrillate' (extra 'f').
- Incorrect part of speech: using 'defibrillate' as a noun (e.g., 'use a defibrillate').

FAQ
Frequently Asked Questions
'Defibrillate' specifically means to stop chaotic fibrillation (like VF) with an unsynchronized shock. 'Cardiovert' typically refers to a synchronized shock used for other abnormal rhythms like atrial fibrillation, timed with the heartbeat.
No. Defibrillation is only effective for specific 'shockable' rhythms like ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT). Asystole (flatline) is not a shockable rhythm.
While most common in human medicine, the term can also be used in veterinary contexts for treating animals with cardiac arrhythmias.
The primary noun is 'defibrillation'. The device used is called a 'defibrillator'. A person who performs it is not given a specific title (e.g., doctor, paramedic).
