As an additional safety precaution the battery and  contact terminals 
should be checked for corrosion at regular intervals. Use of other than 
the recommended batteries may result in one of the following 
conditions:  

 

(1) less than 24 hours of operation after the low-battery indicator 
comes on,  
(2)  degraded pacemaker performance, and/or (3) overall reduced 
battery life.

MODE DEFINITIONS 

 

 

Single Chamber Modes 

 

The Model Zeus-1 will pace in four single chamber modes: AOO, VOO, AAI, and VVI. 
 

  AOO and VOO Modes 

 

The asynchronous mode (A00 and VOO) emit a pacing pulse into one chamber, either the 
atrium (AOO) or the ventricle (VOO),at the end of the base rate interval, regardless of 
any intrinsic activity. When pacing in the A00 mode, the pacemaker will pace the atrium 
asynchronously at the programmed base Rate

. 

The atria and ventricular channels are 

continuously blanked. When pacing in the VOO mode, the pacemaker will pace the 
ventricle asynchronously at the programmed base Rate

. 

 

 

   AAI and VVI Modes 

 

In the inhibited (or demand)  modes (AAI and VVI), when an intrinsic beat is sensed 
outside of a refractory period and before timeout of the base rate interval, the pacemaker 
inhibits the output pulse. If no intrinsic beat is sensed before the timeout of the base rate,
