Overview

Acute hemodynamic gains from pacing outside slow conduction in CRT; hypothesis-generating case report that leaves open prospective validation.

Structured PICO

Does pacing outside regions of slow conduction improve hemodynamics and left ventricular activation in patients with heart failure undergoing CRT?

P
Population
10 patients with heart failure implanted with biventricular pacemakers
I
Intervention
Biventricular pacing outside regions of slow conduction (identified via non-contact mapping)
C
Comparator
Biventricular pacing in regions of slow conduction
O
Outcome
Left ventricular activation time, cardiac output, and dP/dt(max)surrogate

Non-contact mapping can identify regions of slow conduction in CRT patients, and pacing outside these areas significantly improves acute hemodynamic parameters.
