Web02. dec 2024. · By counting the number of QRS complexes that occur in a given time period, one can determine the heartbeat rate of an individual. The ECG obtained from different individuals has roughly the same shape for a given lead configuration, any deviation form this shape indicates the abnormality or disease. Hence, it is of great clinical significance. WebKardia Advanced Determination “Sinus Rhythm with Wide QRS” indicates sinus rhythm with a QRS, or portion of your ECG, that is longer than expected. This could indicate a bundle branch block in which there is a delay in the passage of heart's electrical signals along the bottom of the heart. The electrical signal to make the heartbeat starts ...
