动物心脏起搏器 EP 6877，体积小重量轻，专为实验动物设计，用于心衰及心律失常研究。脉冲振幅宽度和频率可调的，这可提供高频率搏动，高达460次脉冲每分钟。在过去10年中，在美国这个起搏器已成功地用于清醒的狗和兔子心衰研究。该器配有延长线和心肌起搏导联。

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.
