Pacemaker & ICD Implants

Regulating Heart Rhythm 

There are several devices that use electrical signals to regulate arrhythmias, or heartbeats that beat too fast, too slow or have an irregular pattern. Known as pacemakers and implantable converter defibrillators — or ICDs for short — these devices are recommended for people at risk for potentially fatal arrhythmias.

Pacemakers

A pacemaker sends electrical signals to keep the heart beating at a steady, normal rate. Placed under the skin, the small device can speed up a slow rhythm, control a fast rhythm and coordinate the heart's chambers.

Implantable Converter Defibrillator (ICD)

An ICD is similar to a pacemaker but larger. An ICD delivers two different levels of electrical shock — a low level to convert an abnormal rhythm back to normal and a high level if the arrhythmia is incredibly severe. It can detect ventricular tachycardia or ventricular fibrillation and send out a shock to reset the heart.
