In ACS, chest pain is the warning sign of ongoing ischemia. In this case, you should get a second defibrillator and perform double sequential external defibrillation (DSED). Simply attach a second defibrillator as shown in the diagram below and deliver max shocks from both devices simultaneously.

After ruling out for ACS, the patient underwent angiography where he was found to have severe stable disease, which was already known. NOTE: Although this case study is from 1995 the misdiagnosis of wide tachycardias "because the patient is stable" remains all-too-common in 2025.

He had several older ECGs on file, here are two examples: 6 days prior: 2 months prior: In the context of ACS symptoms, and when able to compare the new vs. old ECG, the top ECG is DIAGNOSTIC of OMI until proven otherwise. Defibrillation was performed, and ROSC was achieved. Today's initial ECG is not an easy tracing to interpret.

Whenever I see PVCs with the morphology and axis seen in todays case I always look for signs of AC ( Arrhythmogenic Cardiomyopathy ). See this case for an in-depth discussion of AC and an example of VT and ECG changes associated with this disorder. Arrhythmogenic cardiomyopathy often manifests with PVCs from the RV. 3] Lavalle, C.

Several 200 J shocks did not terminate the VF, so a second defibrillator was applied for double sequential defibrillation with 400 J. She was defibrillated perhaps 25 times. After completing the ACS algorithm with amiodarone and lidocaine, there are diminishing returns on further treatments. SanzRuiz, R., Solis, J., &
