Electrocardiogram signal processing method and apparatus, and related device

A heart failure early-warning apparatus based on electrocardiogram signals, comprising:

• a signal acquisition module, configured to acquire electrocardiogram signals of an object from which electrocardiogram signals are collected in a resting state from a first preset quantity of leads, wherein the leads comprise a second preset quantity of limb leads, and the second preset quantity is less than the first preset quantity;
• a signal processing module, configured to perform data processing on the electrocardiogram signals in the resting state to obtain a static high-frequency QRS waveform feature set, wherein the static high-frequency QRS waveform feature set comprises a QRS duration, a quantity of a first positive index, a quantity of a first target lead and a quantity of a target limb lead;
• for each of the leads, the first positive index is for characterizing that a high-frequency morphological index corresponding to the lead is greater than a first threshold;
• the high-frequency morphological index is a ratio of a first total area to a second total area corresponding to the lead;
• the first total area is a total area of a reduced amplitude zone of the electrocardiogram signal in the resting state corresponding to the lead;
• the second total area is a total area under an envelope of the electrocardiogram signal in the resting state corresponding to the lead;
• the first target lead is a lead for which a total quantity of times the electrocardiogram signal in the resting state is in a downward trend exceeds a second threshold, and the target limb lead is a limb lead for which a QRS complex voltage of the electrocardiogram signals in the resting state is less than a third threshold;
• and
• an assessment and analysis module, configured to acquire a risk assessment score of heart failure based on a risk assessment feature set, wherein the risk assessment score of heart failure indicates a risk of the heart failure of the object from which electrocardiogram signals are collected, and the risk assessment feature set comprises the static high-frequency QRS waveform feature set;
• and
• a module, configured to issue a heart failure warning based on the risk assessment score of heart failure.
