Abstract: Left ventricular hypertrophy(LVH) is maladaptive response and risk factor in chronic pressure overload. Increased myocardium results in diastolic and/or systolic failure, atrial fibrillation and sudden death. As hypertrophic growth slow and clinically invisible, early diagnosis is essential to control the mortality and morbidity. Literature Survey on proposed method could not fetch any search results on Google Scholar.
Study aims at establishing indices for diagnosis of LVH by using safe and non invasive techniques and to indicate modification in autonomous nervous system in hypertensive subjects.
Methods and subjects: Conformative diagnostic indices obtained from 2-lead ECG sample collected for 3-5 minutes duration. Novel algorithm computs an index That provides a guideline to the echo-cardiologist to conduct echo cardiographic study.
Study was carried out with 26 normal subjects varying in age.sex and economic class, 25 hypertensive and LVH subjects and 27 hypertensives. All the cases were recorded at Fortis-S.L.Raheja hospital Mahim(W).
Essential Results: The values of heart rate, heart rate variability, sympathetic power, total power are significantly higher for hypertensive patients with LVH than the hypertensive and control group.
Principle conclusion: Early diagnosis of LVH by ECG signal Is possible. The p-value was found to be in the range below 0.001.
Keywords: Left ventricular hypertrophy (LVH), heart rate variability (HRV), nonlinear HRV tool, Poincare plot and standard descriptor.
