Inhibition/Filter Characteristics and Input Impedances of QRS‐Inhibited Demand Pacemakers Determined by in vitro Studies
Key result
In vitro testing of QRS-inhibited demand pacemakers revealed a wide variety of inhibition characteristics and input impedances, with significant differences between temporary and permanent units.

Implication
Pacemaker inhibition variability may affect temporary unit selection; leaves open standardized in vitro testing metrics.

In vitro testing of QRS-inhibited demand pacemakers reveals wide variability in inhibition characteristics and input impedances, suggesting that time integral (voltseconds) is a better metric than maximum derivative for describing inhibition.
Cite This Study
Ole‐Jørgen Ohm (1980) studied Pacemaker testing. QRS-inhibited demand pacemakers was evaluated on Inhibition characteristics and input impedances. In vitro testing of QRS-inhibited demand pacemakers revealed a wide variety of inhibition characteristics and input impedances, with significant differences between temporary and permanent units.
