What can be done after someone experiences sudden cardiac arrest?
A. Medical studies have shown that nearly half of all sudden cardiac arrest survivors have another arrest. A doctor such as a heart rhythm specialist will determine the treatment. • Antiarrhythmic drugs may help reduce the occurrence of arrhythmias in some patients. • An implantable defibrillator can treat patients with ventricular tachycardia and ventricular fibrillation. Defibrillation is the only therapy that can stop a sudden cardiac arrest and return the heart to a normal rhythm.
