Voltage, or the strength of the heart’s electrical impulses, is represented on the vertical Y-axis. Each micro-volt, mV, positive electrical current raises the stylus 1cm or one large square. The waveform baseline or bioelectric line is electrically neutral, usually without any deflections, e...
Voltage is measured along the vertical axis. 10 mm is equal to 1mV in voltage. The diagram below illustrates the configuration of ECG graph paper and where to measure the components of the ECG wave form Heart rate can be easily calculated from the ECG strip: ...
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 ...
