The electrocardiograph presents one diagram for each lead. Voltage is presented on the vertical (Y) axis and time on the horizontal (X) axis of the diagram. The ECG paper hassmall boxes(thin lines) andlarge boxes(heavy lines). Small boxes are squares of 1 mm2and there are 5 small boxes...

Lead positioning The diagram shows the positioning of the leads. The relevant ones for a two-lead set-up are labelled RA and LL. (The diagram is for a 3-lead set-up but RA and LL are right for the arrangement used in this Instructable - diagram fromhttps://www.heartelearning.org/lab...
Draw a horizontal line through your lead 1 dot and a vertical line through your aVF dot then draw a line from this intersection back through 0 and this will give you the accurate axis. Figure 5. The axis of the heart – a useful diagram for assessing the cardiac axis using the method ...
Einthoven’s recording is known as the “three lead” ECG, with measurements taken from three points on the body (defining the “Einthoven triangle” — an equilateral triangle with the heart at the centre.) The difference between potential readings from L1 and L2 is what is used to produ...
Generally, lead A is used to detect heartbeats, since the QRS complex is more prominent in this lead. Lead B favors the arrhythmic classification of the types SVEB and VEB [107]. More information regarding this database can be found in [148]. 7.2. EDB The EDB database2 is a ...
Applications based on electrocardiogram (ECG) signal feature extraction and classification are of major importance to the autodiagnosis of heart diseases. Most studies on ECG classification methods have targeted only 1- or 2-lead ECG signals. This limita

Figure 8 shows results for a subject connected in Einthoven lead I configuration. As can be seen, good results are achieved despite the simplicity of the electronic hardware used. The article demonstrates that significant improvements can be achieved with simple hardware combined with attention to ...
