Abstract
Ventricular hypertrophy is the thickening of the muscles in the ventricular chambers of the heart which stiffens and
thickens the cardiac walls giving rise to many complications like arrhythmia, high blood pressure, or even heart failure.
One of the ways to diagnose ventricular hypertrophy is through an Echocardiogram which can be predicted by the
positive large amplitude of Chest Leads [V4–V6] of an Electrocardiogram (ECG). But chest lead application is one of the
complicated more parts of the ECG than limb lead. Here we have tried to predict ventricular hypertrophy with bipolar
limb lead electrocardiogram [L-I, L-II & L-III] without any chest leads which can be easily designed to make an ECG
prototype instead of any sophisticated instruments to increase its global accessibility even in remote areas for the
prediction of ventricular hypertrophy even may be for other diagnosis in future. We acquired electrocardiogram data
sets from the physio-net database, specifically collected data from both normal and hypertrophic patients in an institute.
These data sets were obtained using the same recording device. The Lead-I of the RVH and normal patients were not
satisfactorily distinguishable. However, in this work, it has been established that Lead-I can be used to predict for
identification of LVH patients.

1. Introduction
In remote areas where the availability of high-end instruments and doctors are not available, it becomes hard for people
to be diagnosed with cardiac ailments like hypertrophy in their initial stages. Ventricular Hypertrophy is a heart
condition where the muscles in the ventricular heart chamber thicken and stiffen the blood circulation resulting in
improper pumping of the heart. Ventricular hypertrophy is usually caused due to many reasons namely: gene mutations,
overload of pressure induced by arteriolar vasoconstriction, aortic stenosis, obstructive cardiomyopathy, or even
chronic hypertension. Ventricular hypertrophy can lead to conditions like arrhythmia, ischemia, and heart failure. One
of the usual ways to predict ventricular hypertrophy from an ECG signal is to use the QRS complex amplitude of V4 to
V6 lead. The volume overload in the ventricles is depicted by the amplitude of the R wave and associated direction of
the T wave [1].
The objective is to initially predict ventricular hypertrophy by bipolar limb lead system without any chest limbs. We
took the ECG database of 48 patients of Left Ventricular Hypertrophy (LVH), 18 patients of Right Ventricular
Hypertrophy (RVH), and 48 normal patients collected by the same device (CS-12) of the same hospital. We compared
the ECG of both LVH and RVH patients and noted that the amplitude of Lead-I of RVH patients is not that much
distinguishable with normal ECG whereas it is highly distinguishable with the LVH patient [1].
