[0051] Example 1
[0052] like Figure 1 As shown, an embodiment of the present invention provides an automated diagnostic method for real-time detection of cardiac abnormalities, comprising:
[0053] Step 101: Acquire cardiac information of the heart in real time, wherein the cardiac information includes: heartbeat interval signal, initial intensity of sympathetic nerve activity, and initial intensity of parasympathetic nerve activity;
[0054] Step 102: setting a cardiac rhythmic fluctuation monitoring model based on the cardiac information to monitor the cardiac rhythmic fluctuation;
[0055] The relationship between heart rate variability and biological signals: Heart rate variability reflects the balance of the autonomic nervous system (sympathetic and parasympathetic nerves). It is manifested by the fluctuation of the time interval between heart beats (RR interval). This fluctuation pattern can be regarded as the manifestation of a high-dimensional nonlinear system.
[0056] Nonlinear Chaotic System Modeling: We assume that the rhythmic fluctuations of the heart are driven by a nonlinear chaotic system whose state can evolve over time and has strong nonlinear characteristics. We define this model as a high-dimensional system that describes the cardiac rhythm and model it through a dynamic equation.
[0057] Specifically, we use the heartbeat interval signal To represent the changes in cardiac rhythm, we can construct a new chaotic system and use a phase space to describe the time-varying nature of each RR interval. The cardiac rhythm fluctuation monitoring model includes:
[0058] ,
[0059] in, For time The heartbeat interval signal, is the first adjustment factor of the cardiac rhythm fluctuation monitoring model, is the second adjustment factor of the cardiac rhythm fluctuation monitoring model, is the third adjustment factor of the cardiac rhythm fluctuation monitoring model, It is the fourth adjustment factor of the cardiac rhythm fluctuation monitoring model.
[0060] Step 103: setting a heart rate variability evolution model based on the heart information to monitor the heart rate variability evolution;
[0061] Specifically, this embodiment designs a new model to represent fluctuations in heart rate variability (HRV). This model describes changes in heart rate using dynamic equations based on a feedback mechanism. Assuming two primary influencing factors in the system: sympathetic nerve activity and parasympathetic nerve activity, this embodiment defines a new dynamical system to describe the effects of these factors on heart rate fluctuations. This dynamical system, which represents the heart rate variability evolution model, includes:
[0062] ,
[0063] ,
[0064] in, is the initial intensity of sympathetic nerve activity, is the attenuation coefficient of sympathetic nerve activity, which is used to control the decay rate of sympathetic nerve activity in a relaxed state. is the first adjustment factor of the heart rate variability evolution model, is the second adjustment factor of the heart rate variability evolution model, is the initial phase of the intensity of the sympathetic nerve activity, and is the phase offset for controlling the intensity of the sympathetic nerve activity. For time Dynamic feedback variables are used to simulate the adaptive changes of heart rhythm under different physiological states. is the initial intensity of parasympathetic nervous system activity, is the attenuation coefficient of parasympathetic nerve activity, which is used to control the decay rate of the intensity of parasympathetic nerve activity in a relaxed state. is the third adjustment factor of the heart rate variability evolution model, is the fourth adjustment factor of the heart rate variability evolution model, is the initial phase of the intensity of the parasympathetic nerve activity, and is the phase offset for controlling the intensity of the parasympathetic nerve activity. is the fifth adjustment factor of the heart rate variability evolution model, It is the sixth adjustment factor of the heart rate variability evolution model.
[0065] About Time Dynamic feedback variables , this embodiment is explained through the following examples:
[0066] Example 1: General health status
[0067] Assuming a healthy state, The feedback adjustment is smooth, we set:
[0068] 1. The changes are cyclical (normal heart rhythm);
[0069] 2. Initial state = (i.e. the initial feedback variable is equal to the initial heartbeat interval);
[0070] 3. Feedback rate (the sixth adjustment factor of the heart rate variability evolution model) is set to a small constant, assuming =0.1.
[0071] therefore, Tracks smoothly over time For example, suppose Oscillates at a certain period, then It will also adjust slowly to follow changes.
[0072] Example 2: Stress
[0073] Under stress, sympathetic nerve activity increases and heart rhythm changes more dramatically. We set:
[0074] 1. Increased fluctuations in the heart rate indicate an increase in heart rate or irregularity.
[0075] 2. Initial state = However, due to the stress response, the feedback rate Increase, assuming =0.5, which means that the heart rhythm adapts to the current state faster.
[0076] in this case, The changes will follow more quickly Fluctuations in heart rhythm may cause more drastic changes.
[0077] Example 3: Increased parasympathetic nervous system activity (relaxation or sleep state)
[0078] When parasympathetic nerve activity is enhanced, the heart rhythm tends to be stable and the feedback mechanism becomes more effective. We set:
[0079] 1. Becomes more stable and has a lower frequency (indicating a state of relaxation or sleep);
[0080] 2. Initial state = , feedback rate =0.05, reflecting that the feedback process is slow.
[0081] at this time, It adjusts more slowly, following the steady heart rhythm.
