Early diagnosis of LV diastolic dysfunction for diabetic patients

摘要

Left ventricular diastolic dysfunction precipitates to cardiac disorders like myocardial infarction, left ventricular hypertrophy and cardiac artery disease. Raised diastolic left ventricular pressure results in inefficient pumping of the oxygenated blood, leads to LVDD modifying the heart structurally and functionally. An index computed from R-R interval, derived from two-lead, 3-5 minute ECG samples, provides a guideline to the echo-cardiologist. The index values of the diabetic subjects with LVDD are observed to be the lowest, that of diabetic subjects without LVDD are lower than the control group. The index proves to be early, safe, deployable, cost-effective and non-invasive confirmative diagnostic tool.
