Method: A total of 63 patients (40 women, 23 men, mean age 38 +/- 15 years) were included in the study. Each underwent implantation of a Reveal ILR in the left upper chest area midway between the supraclavicular notch and the left breast area. Thirty-two patients received a Medtronic Reveal DX ILR and 31 received Reveal XT device.
Results: In all 62 patients, adequate electrocardiographic tracings were obtained at implant without the need for preoperative cutaneous mapping, and all were followed for a period of 10 +/- 4 months afterwards. The mean P wave amplitude was 0.12 +/- 0.20 mV at implant and at follow-up (6-14 months postimplant); the amplitude was 0.11 +/- 0.19 mV. The peak-to-peak QRS amplitude was 0.48 +/- 0.15 mV at implant and 0.44 +/- 0.16 mV at a follow-up of 6-14 months. The P waves were not detected in two patients at follow-up. In one patient, decreased amplitude of QRS complex resulted in the autoactivation of the device and in one other patient noise was inappropriately oversensed and recorded.
Conclusion: A simple anatomic approach can be used for reveal ILR placement. (PACE 2010; 33:1149-1152).
