ECG CALC - APP OF ECG INTERPRETATION

Introduction and Objective ECG CALC is an application that helps healthcare professionals with little cardiology training to interpret ECG rhythms with great accuracy. Method The user answers a series of simple questions based on the presence, absence, or measurement of various characteristics on a patient’s ECG rhythm. Almost 100 of the most common rhythms seen are included, and can be identified by answering 12 steps (heart rate, rhythm, P wave, PR interval, QRS complex, ST segment, T wave, Q wave, QT interval, U wave, axis and clinical data). The algorithm works by eliminating the problems with incompatible data entries. For example, a ECG with heart rate fast will eliminate "sinus bradycardia". The next step is the exclusion of the differential diagnoses and diagnosis with non-specific data. Results and Conclusions The testing of the initial version with real ECG already analyzed by experts showed that it is possible to achieve similar results of an expert. Of 320 problems found in 150 ECG, 77% had the right diagnosis. The errors were associated with multiple problems that cancel each other (most been corrected), errors in the input data and non parameterized problems. The application has shown that a professional with little knowledge in the interpretation of ECG can reach a precision level close to an expert.
