Results
The day after the implantation, interrogation of the Micra™ AV revealed
satisfactory parameters with a sensed R wave of 11.4 mV, the impedance
of 820 Ω, and threshold of 0.63 V @ 0.24 ms and -> 0.24 ms
and. Chest radiography showed proper Micra location in the mid-RV septum
(Figure 2). Transthoracic echocardiography showed no pericardial
effusion. During 7-month follow-up, the patient was asymptomatic and
free of any complications.
