Fragmented QRS complex frequency and location as predictor of cardiogenic shock and mortality following acute coronary syndrome.

Background: Worldwide, coronary heart disease (CHD) is topping the foremost important chief causes of mortality. Fragmented QRS (f-QRS) is a pattern of QRS complex in 12 leads surface ECG which showed a promising value in predicting the outcome in cardiac diseases including ischemic heart disease. We aimed to research the importance of using f-QRS as a non-invasive and cheap tool for the prediction of cardiogenic shock and mortality in acute coronary syndrome (ACS).
