Method and system for stimulating a mammalian heart
First Claim
1. A method for instantaneously stimulating a mammalian heart, the mammalian heart including a first atrium and a second atrium, comprising:
- receiving a commencement signal;
receiving at least one additional signal;
measuring a plurality of intervals corresponding to the time between two successive signals;
calculating an average interval;
comparing one of the plurality of intervals to the average interval; and
when a difference between the average interval and one of the plurality of intervals is greater than a predetermined time period, instantaneously transmitting a contraction signal to the second atrium.

Abstract
A method for instantaneously stimulating a mammalian heart is provided. The mammalian heart includes a first atrium and a second atrium. A commencement signal is received. At least one additional signal is received. A plurality of intervals corresponding to the time between two successive signals is measured. An average interval is calculated. One of the plurality of intervals is compared to the average interval. Finally, a contraction signal is instantly transmitted to the second atrium when a difference between the average interval and one of the plurality of intervals is greater than a predetermined time period, instantaneously transmitting a contraction signal to the second atrium.

13. An implantable medical device, comprising:
-
a processor;
a controller operably connected to the processor;
at least one sensing lead operably connected to the controller; and
at least one pacing lead operably connected to the controller;
whereina signal is instantaneously sent from the controller to one of the at least one pacing leads to contract a paced atrium when at least one interval calculated from at least two signals received from a sensed atrium via one of the at least one sensing leads is less than an average interval by a predetermined time factor. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
