ABSTRACT
Background:
Patients with permanent pacemakers should be followed-up regularly and parameters recorded during the follow-up visits might present a potential for further diagnostic studies.
Material and methods:
The pilot cross-sectional study upon 127 consecutive patients controlled during pacemaker follow-up was performed.
Results:
The study has revealed, that patients with older ventricular leads (more than 10 years) present increased lead impedance in comparison with patients with newer ventricular leads (less than 10 years) – 512 Ω vs 461 Ω (median values), with no differences in pacing thresholds, percentage of ventricular pacing, presence of ventricular high rate episodes and status of absolute pacemaker dependency.
Conclusions:
This study demonstrates, that parameters obtained from regular pacemaker control differs according to variables like lead age, which opens new field for studies investigating other variables (like disease biomarkers) in correlation with parameters from pacemaker control.
