Abstract
A dual chamber pacemaker system and method provide for safe tracking of PACs. The pacemaker obtains an indication of when the T-wave has occurred within the cycle when the PAC occurs, either by measuring the T wave during the cycle, or by getting a QT interval measure from one or more prior cycles. The pacemaker determines a safe V--V interval as the QT interval measure plus a safety factor, the safety factor being selected so as to insure that a pulse that tracks the PAC does not get delivered during the vulnerable period. A PAC is tracked if and only if the VA interval plus the AV delay is as great as the safe V--V interval.
