Despite a promising association between VF waveform characteristics and prognosis after resuscitation, studies with VF-guided treatment have so far not improved outcomes. While driven by the idea that the VF waveform reflects arrest duration, increasing evidence suggests that pre-existent disease-related changes of the myocardium affect ECG-characteristics of VF as well. In this context, we studied the impact of the left ventricular (LV) diameter and mass. ⋯ Frequency characteristics of VF were consistently lower in case of an increased LV diameter. Whereas LV mass does not affect the frequency of the VF waveform, amplitudes seem higher with increasing mass. These findings add to the current knowledge of factors that modulate VF characteristics of the surface ECG and provide insight into factors which may be accounted for in future studies on VF-guided resuscitative interventions.

Delivery room resuscitation of very low birth weight infants can involve use of endotracheal or intravenous epinephrine. Data of the past 19 years were reviewed to identify the usage of epinephrine in delivery room and identify characteristics of these babies. ⋯ Neonates with lower birth weight and younger gestational age were more likely to receive epinephrine during resuscitation at birth. Use of epinephrine in delivery room was associated with lower survival and severe intraventricular hemorrhage among very low birth weight infants.

Hypoxic brain injury is described in up to 40% of survivors after out-of-hospital cardiac arrest (OHCA). Besides cognitive impairments, lack of circulation may also affect exercise capacity. It is not known if exercise capacity of patients with cognitive impairments differs from other OHCA survivors. ⋯ Based on this small study, there seems to be a correlation between cognitive impairments and lower exercise capacity in patients referred for rehabilitation after OHCA caused by MI. It seems sensible for rehabilitation programs to take the lower exercise capacity of patients with cognitive impairments into account.

Resuscitation guidelines endorse unconscious and normally breathing out-of-hospital victims to be placed in the recovery position to secure airway patency, but recently a debate has been opened as to whether the recovery position threatens the cardiac arrest victim's safety assessment and delays the start of cardiopulmonary resuscitation. ⋯ The recovery position hindered breathing assessment, delayed breathing arrest identification and the initiation of cardiac compressions, and significantly increased the likelihood of not starting cardiopulmonary resuscitation when compared to the results shown when the continuous head tilt and chin lift technique was used.
