New Analysis of Heart Rate Patterns on ECGs May Predict Death Risk From All Causes

Research by Johns Hopkins cardiologists suggests that electrocardiograms (ECGs), which are widely used tests to assess the heart's electrical activity, may have a greater and more profound future role in predicting the risk of death from any cause, not just heart problems. In a study initially designed to determine which patients with heart failure were at highest risk of a dangerous heart rhythm disorder called ventricular tachycardia, and death, the researchers analyzed the ECGs of 850 patients using a new computer algorithm that detects abnormal heart rate patterns. They found a significant correlation between the ECG findings using the special analysis and the patients who died within five years of the test.
