Nowadays, the electrocardiogram keeps having a leading role and a high importance in past, present and future generations and is a very useful medical tool due to its prognostic-diagnostic, preventive and therapeutical value. The objective of the present study was to identify the electrocardiographic anomalies found in consultations, which could have a diagnostic-prognostic value. A total of 2797 electrocardiograms (ECGs) were performed and studied in external patients using a Cardiocid D-200 electrocardiograph manufactured by Combiomed and recorded in a Cardiolib database. ECGs were classified according to anomalies as normal/with marginal anomalies, with minor and major anomalies and were related to age and sex. Among female patients, 807 normal ECGs were registered (63, 32%). Among the 1512 (54,05%) minor and major anomalies-ECGs were present with more frequency (51,71%) in patients 41 to 65 years old and a male sex predominance (59, 52%). In minor anomalies the HVI without ST-T alterations stand out, as well as fascicular block Atrial fibrillation was the most frequent arrhythmia, while the cardiac infarction with Q wave was the commonest finding, as well as the branch blocks and the HIV with ST-T alteration among the major anomalies. We conclude that in almost half of the patients electrocardiographic anomalies were detected. It was possible to identify among the more frequent major alterations the Q wave cardiac infarction, left ventricle hypertrophy with ST-T alterations, atrial fibrillation and branch block. All anomalies could have a predictive value continuing the study.
