Detection of cardiac hypertrophy by ECG analysis

Electrocardiogram (ECG) is a popular non invasive test which records the electrical activity of the heart. Cardiac hypertrophy is an adaptive morphological response of the heart to the work overload and is an important risk factor for myocardial infarction, congestive heart failure and sudden death. P wave and T wave changes along-with rise in QRS complex are some of the indications of Hypertrophy. To design intelligent diagnostic system automatic detection of cardiac hypertrophy is an important landmark. This paper illustrates the algorithm to detect cardiac hypertrophy by analyzing ECG signal. MIT-BIH database and MATLAB software has been used for carrying out experimental analysis.
