Abstract:ObjectiveBy preliminary investigation on electrocardiogram(ECG) examples, we have proved the close connection between “Uturn” phenomenon and heart failure. At this stage we plan to complete and develop the research in this field, and attempt to answer previously remained complex clinical problems with easy methods of ECG. MethodsThe new ECG patterns of 8 patients with heart failure suffering from chest distress or asthma were collected, and they had been treated from November 2015 to January 2017 in our hospital. The electrocardiographic features of heart failure were deeply explored in combination with the “Uturn” phenomenon. ResultsNew ECG patterns illustrated that the “Uturn” phenomenon on ECG is highly reliable in judging heart failure. It helps to judge difficult clinical conditions, and clarify and solve controversial clinical problems.ConclusionThe “Uturn” phenomenon on ECG stretches from the concept of “poor r wave growth” proposed by Zema, which is an important finding in the field of electrocardiology. The utilization of ECG in diagnosing heart failure is worthy of being vigorously promoted.
