Observational data suggesting there are electrocardiographic abnormalities that strongly suggest the presence of chronic heart failure

Abstract

Almost nothing is written about the electrocardiographic abnormalities that may suggest the presence of chronic heart failure. Indeed, one often hears that the electrocardiogram does not indicate anything about the function of the chart. This paper discusses several abnormalities that often predict the presence of chronic heart failure. The information presented is from observations and not from scientific studies. The author urges those who are interested to complete a scientific study based on the premise that such observations may be correct. After all, many scientific studies have been created because of observational data that suggested a certain phenomenon.
