The 'Animal Pacer model EP 6877 is small and lightweight in design for animal use
only Pulse amplitude width and rate are adjustable, which provides high rate pacing up to
460 pulses per min. In the last 10 years, this pacer had successfully been used in pacing-
Induced heart failure in the conscious dog and rabbit in USA. The device comes complete
with extension cable and myocardial pacing lead
Operational Specification
Battery requirement: one standard size 9 volt alkaline battery
Output signal specifications
Pulse amplitude width and rate are adjustable between the following values
Signal Amplitude: Max =8.0 vdc Min=0.8 vdc
Pulse wide Max =4 msec. Min =0.2msec
Pulse Rate: Max=460 pulses per min (interval=130msec
Min=120 pulses per min (interval= 500msec)
Battery life: In excess of 72 days when tested under continuous operation with a 100 ohm
load, 1.0 msec pulse width and 300 pulses per min and a fresh battery to an endpoint of 2.8
volts. Output amplitude on day 1 was 8.0 volts dC and 2. 8 volts on day 72. Battery life in
actual use will vary depending on a variety of conditions hut should be in excess of 60 days
in most cases. The output pulse width and rate did not change over the 72 day test period
Always start
experiment with a fresh battery. Output voltage will fall during prolonged
use, slowly at first, and more rapidly as the battery drains. This causes need for regular
monitoring of the animal and perhaps slight adjustments of the output amplitude to ensure
the cardiac rhythm remains entrained
