VCG vector loop bifurcation |
摘要 |
A system for determining T wave bifurcation that includes three or more ECG leads configured to receive an ECG signal and a first computing device including a processor coupled to a memory, the processor and the memory configured to perform operations including: generating at least two orthogonal ECG vectors based on the ECG signal of a patient, processing the at least two orthogonal ECG vectors to determine a loop trajectory of at least a portion of the ECG signal, identifying a trajectory bifurcation by comparing the loop trajectory to a control loop trajectory for a plurality of cardiac cycles, and determining an indicator of a cardiac event based on the trajectory bifurcation. |

1. A system, comprising:
three or more ECG leads configured to receive an ECG signal; and a first computing device comprising a processor coupled to a memory, the processor and the memory configured to perform operations comprising:
generating at least two orthogonal ECG vectors based on the ECG signal of a patient,processing the at least two orthogonal ECG vectors to determine a loop trajectory of at least a portion of the ECG signal,identifying a trajectory bifurcation by comparing the loop trajectory to a control loop trajectory for at least three consecutive cardiac cycles of a plurality of cardiac cycles,determining a variation of the trajectory bifurcation over time, the determination based on an analysis of the trajectory bifurcation of the at least three consecutive cardiac cycles,displaying an indicator of a cardiac event based on the variation of the trajectory bifurcation, anddelivering a treatment to the patient based on the indicator of the cardiac event. |
