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

Physical Specifications

Dimensions of polyethylene Case

Height=6.0 cm, Width=5.3 cm; Depth=2.1 cm

Total Weight(without battery)26.0 gm

with battery-Duracell)705gm
