Implication

May warrant ECG monitoring during CT over pacemakers; case report leaves open generalizability and shielding protocols pending prospective data.

Does high-power computed tomography scanning equipment induce transient malfunctions in implanted pacemakers?

Population

11 patients with implanted demand-type pacemakers undergoing chest CT scanning for abnormal shadows on chest X-ray, and in vitro human body models (Irnich's model and bench model) implanted with pacemakers.

Intervention

Chest CT scanning using a multislice spiral CT system (4-detector row, 140-150 kV, 100-300 mAs).

Outcome

Transient malfunctions of pacemakers during CT scanning (assessed via continuous ECG monitoring).safety

High-power diagnostic CT scanning can induce transient malfunctions in implanted pacemakers due to direct radiation interference, highlighting the need for ECG monitoring during scans over the device.

Limitations

5 cases did not show pacemaker malfunctions during CT scanning
pacemakers used in experimental studies were both made by the Medtronic Company
further studies using pacemakers from other manufacturers, with different design parameters, are necessary
