Contraindications for Manual Defibrillation Therapy

Asynchronous defibrillation therapy is contraindicated in patients that exhibit
one or any combination of the following:
Responsiveness
Spontaneous breathing
Palpable pulse

Precautions for Manual Defibrillation Therapy

Defibrillating asystole can inhibit the rec ov ery 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 int ended t o
cause cardiac depolarization and myocardial contraction. The emer ge ncy care
provider selects the stimulus current and rate settings. The ener gy is del ivere d
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 patie nts 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.
