Contraindications for Manual Defibrillation Therapy
Asynchronous defibrillation therapy is contraindicated in patients that exhibit
one or any combination of the following:
z Responsiveness
z Spontaneous breathing
z Palpable pulse
Precautions for Manual Defibrillation Therapy
Defibrillating asystole can inhibit the recovery of natural pacemakers in the
heart and completely eliminate any chance of recovery. Asystole should not
be routinely shocked.
Noninvasive Pacing Therapy
The HeartStart XLT provides noninvasive transcutaneous pacing by deliver-
ing a monophasic, electrical stimulus to the heart. This stimulus is intended to
cause cardiac depolarization and myocardial contraction. The emergency care
provider selects the stimulus current and rate settings. The energy is delivered
through multifunction defib electrode pads applied to the patient’s bare chest.
Indications
Noninvasive pacing is one method of treating patients with symptomatic
bradycardia. It can also be helpful in patients with asystole, if performed
early.
Contraindications
Noninvasive pacing is contraindicated in the treatment of ventricular fibrilla-
tion. Noninvasive pacing in the presence of severe hypothermia may be con-
traindicated.
