Structured PICO
Does an atrial automatic capture verification scheme using independent pacing and sensing electrodes accurately detect atrial evoked response in pacemaker patients?
P
Population
27 patients (mean age 65.6 years) undergoing acute or chronic pacemaker implantation.
I
Intervention
Atrial automatic capture verification scheme based on atrial evoked response (AER) using independent pacing (Atip-Can) and sensing (Aring-Vtip or Aring-Indiff) electrodes with different coupling capacitances (2 or 15 microF).
C
Comparator
Visual inspection and comparison with surface ECG to verify captures.
O
Outcome
Correct capture verification rate of atrial paced beats.surrogate
Atrial automatic capture verification by atrial evoked response detection is highly accurate and feasible using independent pacing and sensing electrodes.
Cite This Study
Butter et al. (2001) studied Pacemaker implantation (n=27). Atrial automatic capture verification based on atrial evoked response vs. Visual inspection and surface ECG was evaluated on Correct capture verification rate. Atrial automatic capture verification based on atrial evoked response correctly verified capture in 99.4% to 99.8% of paced beats using independent pacing and sensing electrodes.
