“…Patients cared for by paramedics on board were more likely to be alive 1 month later, which was also comparable with the findings of previous studies, 16,17 and this finding further confirmed that additional life support procedures contribute to a better prognosis. At present in Japan, paramedics on board have to obtain a doctor's permission to perform such interventions as electric defibrillation and airway insertion, which implies that full resuscitation will be somewhat delayed.…”

BackgroundThe factors that influence survival of out-of-hospital cardiac arrest in Japan have not been fully investigated. Methods and ResultsThe official emergency service record was used to investigate 1,600 patients for whom cardiopulmonary resuscitation was attempted by the city's emergency personnel. Only 45 (2.8%) patients survived for 1 month. The survival rate was 9.8% in the patients under 20 years of age, with a marked decreasing trend to 0.8% in the patients aged 80 years or older. The rate peaked at 4.8% on Sunday and bottomed out at 0.5% on Thursday, forming a distinct sine curve. The survival rate was 9.9% when an ambulance arrived at the scene within 4 min, with a steep drop to 2.5% when 4-7 min elapsed. However, the rate was not significantly different by the interval to hospital. Although bystander resuscitation did not significantly affect the survival, paramedics on board significantly improved the rate (3.5% vs 1.6%). Multivariate analysis confirmed that age, day of the week, place, interval to ambulance's arrival, and personnel on board were independently associated with the probability of survival. Conclusions Quick arrival of a paramedic team would improve the survival after out-of-hospital cardiac arrest. General education of lifesaving techniques would be another key factor.

“…Survival rates decrease by 7%-10% for each minute the ventricles fibrillate and thus survival approaches zero percent after 10-12 minutes of ventricular fibrillation. [16][17][18][19][20] The indication for defibrillation is less clear for the other predominant arrest rhythms seen in small animal practice: asystole and pulseless electrical activity. Although there is no indication to apply defibrillatory currents to an asystolic myocardium, it likely does little harm in this setting and occasionally it may turn out that what appeared to be asystole was, in fact, fine ventricular fibrillation.…”

“…Die Zeit vom Kollaps bis zur Defibrillation ist die wichtigste Determinante des Überlebens beim Herzstillstand auf Grund von Kammerflimmern [23]. Ohne Defibrillation nimmt die Überlebensrate um 7-0% pro Minute ab [24].…”

Tachyarrhythmias represent a frequent problem in intensive care medicine. However, considerable uncertainty prevails among physicians regarding optimal pharmacotherapy, due also to numerous negative study results on chronic antiarrhythmic therapy. Moreover, in an emergency situation, the physician faces the dilemma of treating a potentially life-threatening arrhythmia as quickly as possible while simultaneously ensuring adequate diagnostic work-up, which will be decisive for long-term therapy once the patient has survived the crisis. The differential diagnosis between supraventricular and ventricular tachycardias is primarily facilitated by knowledge of a few salient points from the patient's history and 12-lead electrocardiography. This overview presents the most important principles for treating these arrhythmias. Interventional therapy principles (overstimulation, ablation) play an increasing role in these considerations. New insights on the pathogenesis of "malignant" arrhythmias and implementation of new concepts such as defibrillation by lay responders with the automatic external defibrillator will substantially influence emergency treatment of tachyarrhythmias in the coming years.
