An 80-year-old man with renal disease on hemodialysis, coronary artery disease, complete heart block and a dual chamber leadless pacemaker (LP) implanted because of previous bacteremia, presented with syncope. While in the hospital, he had witnessed ventricular fibrillation (VF) arrest for which he received external defibrillation.

Many patients with mild to moderately reduced left ventricular ejection fraction (LVEF) that require permanent pacemaker (PPM) implantation do not have a concurrent indication for implantable cardioverter-defibrillator (ICD) therapy. However, the risk of ventricular tachycardia/fibrillation (VT/VF) in this population is unknown.

If ventricular tachycardia occurs in an Implantable Cardioverter Defibrillator (ICD) wearer, the ICD can combat this with 2 different forms of therapy, provided these are activated (which can be done using a programming device). The fastest pacemaker gets control of the heart. First, the ICD attempts to override the tachycardia.

Quick aside on device terminology (feel free to skip): A "single chamber" pacemaker is a device with only one lead. A "dual chamber" pacemaker is a device with an atrial lead and a ventricular lead.

Your heart's job is to keep your pulse steady to pump blood throughout your body. Sometimes your heart rate is slower when you're relaxing, and sometimes it's faster when you're exercising or stressed. If your heart's ability to keep the beat starts to go awry, cardiac electrophysiologists like me look for outside help from an implantable device.

The timing of the stimuli given by the pacemaker is adjusted to produce synchrony of contractions of the left ventricle. This picture illustrates what reduced ejection fraction means.
