ECG Electrode Placement Guidance via Imaging Landmark Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Incorrect placement of electrocardiogram (ECG) electrodes on a person's torso can lead to compromised diagnostic value of ECG results, with estimated incorrect placement rates as high as 50% by trained technicians.
Innovation Solution
A method and system that utilize an imaging device to acquire an image of the person, identify anatomical landmarks, determine target locations for ECG electrodes based on these landmarks, and highlight these locations for accurate placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a clinician manually locates anatomical landmarks to place ECG electrodes, then the process is simple and quick, but the placement accuracy deteriorates with high error rates up to 50%
Solution Approach 1:
The patent introduces an imaging device as an intermediary tool between the clinician and the patient's body. The device captures images, identifies anatomical landmarks automatically, and provides visual guidance for electrode placement, thereby improving accuracy without requiring the clinician to manually locate landmarks
Solution Approach 2:
The patent replaces the manual mechanical process of landmark location with an automated imaging and image processing system. The computer-based system automatically identifies landmarks and calculates electrode positions, substituting human manual measurement with automated digital processing
2Reliability
If anatomical landmarks are used as reference for electrode placement, then the method is universally applicable, but the reliability deteriorates when landmarks are difficult to locate such as in obese individuals
Solution Approach 1:
The patent creates a visual copy or representation of the patient's anatomy through imaging. The system processes the captured image to identify landmarks and generates visual guidance overlays, allowing the clinician to see the correct electrode positions without directly relying on difficult-to-locate physical landmarks
Solution Approach 2:
The patent substitutes the difficult manual detection of physical landmarks with automated image processing algorithms. The computer-based system detects landmarks from images, overcoming the limitations of manual detection in challenging anatomical conditions
3Reliability
If precise electrode placement is required to avoid diagnostic errors, then the diagnostic accuracy improves, but the time and complexity of the placement process increases
Solution Approach 1:
The patent performs preliminary actions by automatically identifying anatomical landmarks and calculating optimal electrode positions before the actual electrode placement. The system prepares visual guidance showing all target positions in advance, allowing the clinician to quickly place electrodes without time-consuming manual measurements
Solution Approach 2:
The patent replaces time-consuming manual measurement and calculation processes with automated computer-based image processing. The system rapidly analyzes images, identifies landmarks, and computes electrode positions algorithmically, significantly reducing the time required compared to manual methods

AI summary
A method for guiding electrocardiogram (ECG) electrode placement on a person includes acquiring an image of the person, identifying an externally discernable anatomical landmark on the image, determining target locations for first through nth electrodes as a function of the location of the landmark, and highlighting the target locations on the person. A system for guiding placement of ECG electrodes comprises an imaging device, an illumination source, a processor, and machine readable instructions. The instructions, when executed by the processor, identify at least one marker in an image acquired by the imaging device, determine, as a function of the location of the at least one marker, target locations on the person at which first through nth ECG electrodes should be placed, and cause the illumination source to illuminate the first through nth target locations.
