“…These data are highly consistent with previous publications that demonstrated an association between major train stations and SCA. 18,19,[31][32][33][34][35] A differential proportion in resuscitation attempted by EMS (according to the location of SCA) may have led to a significant reporting bias. This has not been observed, however, with a very similar proportion of SCA with resuscitation attempted being observed in different public places (train stations versus areas other than train stations).…”

“…9,10 Although previous studies have identified sites with a higher risk of SCAs, [18][19][20][21][22] especially raising the association with train stations and airports, the reliability and determinants of such high-risk places have been only partially explored. In this study, we collected data on SCA locations in Paris.…”

Public-access defibrillation programs have thus been developed to make automatic external defibrillators (AEDs) publicly available, allowing rapid early defibrillation. 11-17Although the benefits of AED are undeniable, public use rates remain very low, 4,15,18 and thus the effectiveness of such programs could be dramatically improved. One of the key issues is the disparity between the locations of AEDs and SCAs. In Paris, although AED deployment in the community, which started in 1993 with the progressive equipping of EMS ambulances, has been particularly active over the last decade, the choice of where to install AEDs in public places has been driven mainly by empirical considerations (local unguided initiatives). Recent studies have already pointed out the limitations of such an approach, calling for an evidence-based strategy.

“…Early defibrillation improves the survival of victims of sudden cardiac arrest 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16. However, it is often difficult to shorten the time from the cardiac arrest to the defibrillation utilizing the emergency medical service.…”

BackgroundAlthough automated external defibrillators (AEDs) have contributed to a better survival of out‐of‐hospital cardiac arrests, there have been reports of their malfunctioning. We investigated the diagnostic accuracy of commercially available AEDs using surface ECGs of ventricular fibrillation (VF), ventricular tachycardia (VT), and supraventricular tachycardia (SVT).Methods and ResultsECGs(VF 31, VT 48, SVT 97) were stored during electrophysiological studies and transmitted to 4 AEDs, the LifePak CR Plus (CR Plus), HeartStart FR3 (FR3), and CardioLife AED‐2150 (CL2150) and ‐9231 (CL9231), through the pad electrode cables. For VF, the CL2150 and CL9231 advised shocks in all cases, and the CR Plus and FR3 advised shocks in all but one VF case. For VTs faster than 180 bpm, the ratios for advising shocks were 79%, 36%, 89%, and 96% for the CR Plus, FR3, CL2150, and CL9231, respectively. The FR3 and CR Plus did not advise shocks for narrow QRS SVTs, whereas the CL9231 tended to treat high‐rate tachycardias faster than 180 bpm even with narrow QRS complexes. The characteristics of the shock advice for the FR3 differed from that for the CL9231 (kappa coefficient [κ]=0.479, P<0.001), and the CR Plus and CL2150 had characteristics somewhere between the 2 former AEDs (κ=0.818, P<0.001).ConclusionsCommercially available AEDs diagnosed VF almost always correctly. For VT and SVT diagnoses, a discrepancy was evident among the 4 investigated AEDs. The differences in the arrhythmia diagnosis algorithms for differentiating SVT from VT were thought to account for these differences.
