[Follow-up]
6-month follow-up showed safe and stable output of pacing with atrial
pacing rate (AP) of 83.3%, ventricular pacing rate (VP) of 100%,
atrium impedance 551Ωand sensing 3.1mV, left ventricle impedance 304Ω,
right ventricle (RV) impedance 418Ωand sensing 5.4mV, no change of ECG
or echocardiogram features [Fig3] .
1.5-year follow-up showed disappearance of previous symptoms with no
recurrence, improvement of quality of life and exercise capacity, high
patient satisfaction.
There were no adverse events associated with the ablation and
implantation procedure, device operation or disease.
