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.
Claims26
A system for synchronizing application of treatment signals with a cardiac rhythm, comprising:
- a memory that receives and stores a synchronization signal indicating that a predetermined phase of a cardiac rhythm of a patient has started;
- and
- a synchronization module coupled to the memory and operable to automatically extend a blanking period when the stored synchronization signal is determined to be received during the blanking period.
A system for synchronizing application of treatment signals with a cardiac rhythm, comprising:
- a memory that receives and stores a synchronization signal from a cardiac device that continuously generates the synchronization signal indicating that a predetermined phase of a cardiac rhythm of a patient has started;
- and
- a synchronization module coupled to the memory and operable to start a blanking period upon receipt of the synchronization signal and to use and automatically adjust the duration of the blanking period to prevent a medical treatment device from applying a treatment signal when the stored synchronization signal is determined to be received during the blanking period.
A system for synchronizing application of treatment signals with a cardiac rhythm, comprising:
- a memory that stores a synchronization signal from a cardiac device that continuously generates the synchronization signal indicating that a predetermined phase of a cardiac rhythm of a patient has started;
- and
- a synchronization module coupled to the memory and operable to automatically and dynamically adjust the duration of a blanking period during which an application of treatment signals to the patient by a medical treatment device is prevented when the stored synchronization signal is determined to be received during the blanking period.
A method of synchronizing application of treatment signals with a cardiac rhythm, comprising:
- continuously receiving a synchronization signal which indicates that a predetermined phase of a cardiac rhythm of a patient has started;
- and
- determining whether the received synchronization signal is received during a blanking period;
- and
- extending the blanking period and preventing a medical treatment device from applying a treatment signal to a patient when the received synchronization signal is received during the blanking period.
