Abstract
Abstract A pacemaker assembly having a ventricular inhibited pacemaker unit set to produce a signal for application to a patient's heart at a first rate of time and a ventricular triggered pacemaker unit set to produce a signal for application to a patient's heart at a second rate of time lower than said first rate of time, both units being contained within a housing and being independently operative with respect to one another.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
79 words
A pacemaker assembly comprising: a housing, a ventricular inhibited pacemaker unit set to produce a signal for application to a patient's heart at a first rate of time, a ventricular triggered pacemaker unit set to produce a signal for application to a patient's heart at a second rate of time lower than said first rate of time, the ventricular inhibited and ventricular triggered pacemaker units being contained within said housing and being independently operative with respect to one another.
Claim 2
Dependent Claim
79 words
A pacemaker assembly comprising: a housing, a ventricular inhibited pacemaker unit set to produce a signal for application to a patient's heart at a first rate of time, a ventricular triggered pacemaker unit set to produce a signal for application to a patient's heart at a second rate of time lower than said first rate of time, the ventricular inhibited and ventricular triggered pacemaker units being contained within said housing and being independently operative with respect to one another.
Claim 3
Dependent Claim
23 words
