Clinical, electrophysiologic and hemodynamic profile of patients resuscitated from prehospital cardiac arrest

摘要: Abstract Of 352 prehospital cardiac arrest patients studied during a three year period, the initial mechanism recorded by rescue personnel was ventricular fibrillation in 220 (62 per cent), tachycardia 24 (7 cent) and bradyarrhythmias or asystole 108 (31 cent). Early survival best group with (16 of resuscitated survived hospitalization—67 cent); prognosis worst (nine admitted to hospital alive—none hospitalization); 51 (23 were subsequent hospitalization, significantly better outcome than previously reported for fibrillation. Central nervous system damage accounted directly indirectly 28 48 in-hospital deaths (59 hemodynamic abnormalities 31 cent. Only five (10 primary arrhythmic. The majority survivors had evidence left (mean end-diastolic pressure=17.80 ± 8.99 mm Hg; mean index=2.62 0.72 liters/min/m 2 ; ejection fraction=38.58 17.55 but approximately one third surviving normal function. electrophysiologic data demonstrated persistent, drug-resistant complex arrhythmias first 72 hours; intracardiac studies elicited specific patterns only tachycardia, whose reproducible six studied. risk recurrent hours predicted coexistent conducting abnormalities, persistent arrhythmia alone. We conclude that electrical provides early prognostic information, rates are improving discharged have indices presence identifies subgroup at high
