This rhythm is a regular wide-complex tachycardia at 170 bpm with no visible P waves. The patient is hypotensive and diaphoretic.
What is unstable monomorphic ventricular tachycardia?
First-line medication for symptomatic bradycardia.
What is Atropine?
You defibrillate VF. Rhythm remains VF
What is resume CPR immediately for 2 minutes?
The maximum time you should pause compressions during rhythm checks.
What is less than 10 seconds?
The button you press to analyze a rhythm during cardiac arrest.
What is Analyze?
This rhythm is irregularly irregular at 150 bpm, has no discernible P waves, and narrow QRS complexes. The patient is stable.
What is atrial fibrillation with rapid ventricular response?
(Next step: rate control.)
Medication given every 3–5 minutes during cardiac arrest
What is Epinephrine?
You give Adenosine for SVT and nothing changes.
What is give a second dose (12 mg)?
The recommended compression depth for adults.
What is at least 2 inches (5 cm)?
The recommended adult biphasic starting energy for defibrillation on a ZOLL
What is 120–200 joules (typically 200J if unknown)?
This rhythm shows P waves marching through at a regular rate, but there is no consistent relationship between P waves and QRS complexes. The ventricular rate is 35 bpm and QRS complexes are wide.
What is third-degree AV block (complete heart block)?
(Next step: pacing.)
Antiarrhythmic given after the third shock for refractory VF/pVT per American Heart Association ACLS guidelines.
What is Amiodarone?
You start pacing at 70 bpm, but no capture is noted.
What is increase milliamps until electrical and mechanical capture?
Waveform capnography reading that indicates high-quality CPR.
What is ETCO₂ ≥ 10 mmHg (ideally 20+ mmHg)?
The pacing rate typically set first when initiating transcutaneous pacing.
What is 70 bpm?
This rhythm appears chaotic with no identifiable QRS complexes. The patient is pulseless.
What is ventricular fibrillation?
(Next step: defibrillation and CPR.)
Medication used for stable narrow-complex SVT that may cause a brief period of asystole.
What is Adenosine?
Post-ROSC BP is 78/40.
What is start IV fluids and initiate vasopressor infusion?
Reversible causes of cardiac arrest are remembered by this mnemonic.
What are the H’s and T’s?
This feature provides real-time feedback on compression depth and rate.
What is CPR feedback/Real CPR Help?
This rhythm is a regular narrow-complex tachycardia at 190 bpm. P waves are not clearly visible. The patient is stable but symptomatic.
What is supraventricular tachycardia (SVT)?
(Next step: vagal maneuvers → adenosine.)
Vasopressor infusion often used post-ROSC to maintain MAP ≥65 mmHg.
What is Norepinephrine?
During intubation, ETCO₂ suddenly drops from 35 to 8.
What is check tube placement, assess for dislodgement, and resume high-quality CPR if arrest suspected?
Targeted oxygen saturation after ROSC.
What is 94–99%?
During synchronized cardioversion, failure to see markers over QRS complexes means this problem.
What is the sync mode not properly detecting R waves (increase gain or reposition leads)?
