BackgroundSudden cardiac arrest is a common mechanism of premature death in the community. Resuscitation is often possible, but no large study of resuscitation by doctors who practice there has been published.MethodsGeneral practitioners (GPs) equipped with defibrillators reported 555 patients with cardiac arrest in whom they attempted resuscitation.FindingsAverage age was 65.4, 75% male. Most arrests (49%) occurred at the patient's home but some (18%) occurred at or near the doctors' surgeries. Heart disease was responsible for 88% of the arrests: in these cases resuscitation to leave hospital alive was frequently successful (148 of 436 attempts, 34%). Success was rare (one of 59, <2%) when the arrest was due to non-cardiac disease. Resuscitation was most common when the first monitored rhythm was shockable (VF/VT) and defibrillated promptly: 144 out of 351 (41%) patients surviving. VF/VT was most common with early rhythm monitoring, particularly when the doctor was present (63% survival), or nearby (54%). When VF/VT complicated AMI, 72% of those defibrillated within 1min of onset survived. With delayed attendance, the frequency of VF/VT fell and asystole or Pulseless Electrical Activity (PEA) became more common. Survival after resuscitation was rare for patients presenting with these rhythms: five of 202 (2.5%). No such patient survived unless the rhythm could be converted to VF/VT with drugs or basic life support and subsequently shocked.ConclusionPrimary care doctors equipped with defibrillators attend patients with cardiac arrest under circumstances in which resuscitation is frequently successful. This presents a unique opportunity to reduce mortality from sudden cardiac arrest.
