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 Specifications:

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 a new 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.
