1. A system for synchronizing application of treatment signals with a cardiac rhythm, comprising:
- a cardiac device that receives a first synchronization signal indicating that a patient is in a predetermined phase of a cardiac rhythm; and
a synchronization module coupled to the cardiac device to receive the first synchronization signal, a blanking period beginning after receiving the first synchronization signal, the synchronization module operable to automatically extend the blanking period the moment a second synchronization signal is received during the blanking period, the synchronization module automatically extends the blanking period from the time the second synchronization signal is received without ever stopping the blanking period to prevent the treatment signal from being applied to the patient during the extended blanking period.

Abstract
A system for synchronizing application of treatment signals with a cardiac rhythm is provided. The system includes a memory that receives and stores a synchronization signal indicating that a predetermined phase such as R-wave of a cardiac rhythm of a patient has started. A synchronization module analyzes whether the stored synchronization signal is erroneous and if so, prevents a medical treatment device from applying a treatment energy signal such as an IRE pulse to a patient to take into account an irregular heart beat and noise in the synchronization signal in order to maximize safety of the patient.

10. A system for synchronizing application of treatment signals with a cardiac rhythm, comprising:
-
a cardiac device that continuously generates a first synchronization signal indicating that a patient is in a predetermined phase of a cardiac rhythm; and a synchronization module coupled to the cardiac device to receive the first synchronization signal, a blanking period beginning after receiving the first synchronization signal and operable to automatically extend the blanking period when a second synchronization signal is received during the blanking period to prevent the treatment signal from being applied to the patient during the blanking period, resulting in a continuous blanking period of between 560-800 milliseconds. - View Dependent Claims (11, 12, 13, 14, 15)

16. A system for synchronizing application of treatment signals with a cardiac rhythm, comprising:
-
a cardiac device that continuously generates a first synchronization signal indicating that a patient is in a predetermined phase of a cardiac rhythm; and an energy delivery control device that continuously receives the first synchronization signal from the cardiac device, a blanking period beginning after receiving the first synchronization signal, the energy delivery control device operable to automatically extend the blanking period when a second synchronization signal is received during the blanking period before the blanking period ends to prevent the treatment signal from being applied to the patient during the blanking period, wherein both the cardiac device and the energy delivery control device are both external to the patient'"'"'s body.
