Wireless pacemaker

Case contributed by Dr Fahad Dilawez Rathore

Patient Data

Age: 80 years
Gender: Male

Small pill-shaped device with short metallic connectors demonstrated overlying the heart on this plain film. This is a wireless pacemaker, otherwise known as a leadless cardiac pacemaker.

Other findings on this film include a right-sided central venous line with its tip projected in the right atrium, as well as bilateral interstitial and alveolar edema with small pleural effusions suggestive of a degree of cardiac failure.

Case Discussion

As technology advances, devices are getting smaller, smarter and wireless. Cardiac pacemaker technology is no exception to this rule.

It is important to not get caught out and confuse these with implantable loop recorders. Despite loop recorders also getting smaller in size they remain longer and more rectangular in shape reminiscent of a USB stick, whereas these are more cylindrical pill-shaped with more rounded edges.
