Key result
Moderate hypothermia (33°C) dramatically reduced the duration of induced VT/VF compared with normothermia and severe hypothermia by increasing spiral wave collision and self-termination.
Why the study?
Does moderate hypothermia reduce the duration of VT/VF in Langendorff-perfused rabbit hearts compared to normothermia and severe hypothermia?
Does moderate hypothermia reduce the duration of VT/VF in Langendorff-perfused rabbit hearts compared to normothermia and severe hypothermia?
Moderate hypothermia promotes self-termination of VT/VF by modifying spiral wave dynamics to increase the chance of spiral wave collision.

May support moderate hypothermia for VT/VF self-termination; hypothesis-generating in animal models and requires clinical validation.
Harada et al. (2008) studied Ventricular tachycardia/fibrillation (n=13). Moderate hypothermia vs. Normothermia (37 degrees C) and severe hypothermia (30 degrees C) was evaluated on Duration of direct current stimulation-induced ventricular tachycardia (VT)/VF. Moderate hypothermia (33°C) dramatically reduced the duration of induced VT/VF compared with normothermia and severe hypothermia by increasing spiral wave collision and self-termination.
