An electrocardiogram is a picture of the electrical conduction of the heart. By examining changes from normal on the ECG, clinicians can identify a multitude of cardiac disease processes. There are ...

The Q wave is the first downward deflection after the P wave and the first element in the QRS complex. When the first deflection of the QRS complex is upright, then no Q wave is present. The normal ...

To generate and analyze a real-time ECG signal using MATLAB, introduce noise, and apply digital filtering techniques to remove unwanted interference, thereby improving the quality of the signal. The ...
