Once again, it has been assumed that no atrial sense events have occurred and that the atrial upper rate limit timer has timed out (AURLTO). In Boolean notation, this second atrial pace sequence may be expressed
Unfortunately, it has been shown that, in order to be certain of reliable determination of the onset of battery failure, it is necessary to make pacer tests as frequently as once a week during the last few months of battery life. This is a result of the fact that the battery cell ...
which probably comprised one of the most critical factors that led to the advanced snakes’ species radiation. It has been proposed that the tremendous
of life ignore the fact that it is not only battery impedance which is important in determining when the parameter values should be changed automatically so as to conserve the battery. It is just as important to take into account the average current drawn from the battery as it is to take ...
It has actually been found that the second stimulus may be more effective than the first. As used herein, the time period between a heartbeat and the first stimulus is referred to as the "initial delay", and the time period between the first stimulus and the second stimulus is referred ...
Once the event status summary record has been produced, it is scanned via a computed "key" access (based on the channel, the number of records, and status indicator) to the record, to determine the operational status of each of the pacemaker's functions (sensing, pacing, timing and capture...
