Single chamber temporary pacemakers

The Advisa DR MRI and Advisa SR MRI Sure Scan systems are indicated for the rate adaptive pacing in patients who may benefit from increased pacing rates concurrent with increases in activity.

Five patients (0.5%) required reoperation for generator erosion (two dual, three single chamber, P = not significant).

and a further five for drainage of haematoma or a serous fluid collection (three dual, two single chamber, P = not significant).

Any other combination may result in a hazard to the patient during an MRI scan.

OBJECTIVE--To evaluate the incidence of intraoperative and early postoperative complications (up to two months after implant) of endocardial permanent pacemaker insertion in all patients under-going a first implant at a referral centre.

METHODS--Prospective evaluation of all endocardial pacemaker implantation procedures performed from April 1992 to January 1994 carried out by completion of standard audit form at implant.

Complications that did not require reoperation were also rare. Atrial undersensing (n = 8) was significantly more common than ventricular undersensing (n = 2, P = 0.017).

All patients were successfully treated by reprogramming of sensitivity.

A temporary pacing lead was present at implant in 22.9% of patients.

Most (93.6%) implants were performed via the subclavian vein.

There was no difference in electrode displacement rates for dual (1.6%) compared with single (1.2%) chamber systems.
