This invention discloses a timing device that integrates multiple emergency operation buttons and generates structured medical records in real time, belonging to the field of emergency medical technology. It includes an intelligent terminal recording module, a data integration and communication module, and an intelligent processing and output module. These three modules work together to achieve real-time recording of emergency operations, integrated data transmission, and automatic generation of structured medical records. The intelligent terminal recording module is a dedicated emergency recording terminal equipped with a timing chip and a multi-touch screen. The touch screen interface is dynamically designed according to the ACLS / BLS resuscitation process and features one-button recording for various emergency operations such as chest compressions, bag ventilation, defibrillation, heart rhythm analysis, and adrenaline administration. The timing chip provides millisecond-level timestamps for emergency operation records, enabling precise binding of operation content to the time of occurrence. This significantly reduces the need for clinical manpower, eliminating the need for a dedicated recording nurse through an "operation-as-record" model, and also eliminating the need for manual re-entry of medical documents after resuscitation.

During a cardiac arrhythmia, defibrillation shocks from an implanted cardiac defibrillator are suppressed based on the sensing of electrical wavefront arrival times which indicate a supraventricular origin to the cardiac arrhythmia. In some embodiments, times of electrical wavefront arrival in at least two ventricular locations of the heart are sensed; one location being relatively superior, and one relatively inferior (e.g., relatively superior and inferior locations of a ventricular septum). In some embodiments, if the arrival time at the more inferior position is within a predetermined interval after arrival at the more superior position, delivery of defibrillation shocks are suppressed. In some embodiments, additional sensing of electrical wavefront arrival at one or more non-septal ventricular locations is performed, and defibrillation shock suppression is optionally itself suppressed if the additional sensing indicates that the wavefront initiated in a ventricular location.
