| Summary: | The conduction system of the heart initiates the normal cardiac cycle and coordinates
contraction of cardiac chambers (atria and ventricle).The electrical events in the
heart can be recorded on an electrocardiogram (ECG). ECG 12 lead usually be
interpreted using Einthoven’s parameter from limb lead and precordial lead. ECG
signal is interpreted in separated lead until now.
ECG signal processing method is proposed to know sequence contraction direction of
the heart in this research. Two or more ECG leads extraction can give spatial
information. Spatial information is used to show contraction direction of the heart. P
parameter ECG from limb lead and precordial lead extraction shows atrium
contraction from right to left side. R parameter ECG from limb lead and precordial
lead extraction shows ventricle contraction from left to right side. Sequence of
contraction direction of heart’s atria and ventricle is used to know normal condition
and ten heart’s problems (atrial fibrilation, left atrial enlargement , right atrial
enlargement, ventricular fibrilation, left ventricular hypertropy, right ventricular
hypertropy, left bundle branch block, right bundle branch block, left anterior
fascicular block and left posterior fascicular block). Contraction direction
visualization in four hexagonals give information about contraction direction of
heart’s atria and ventricle.
Using primary and secondary data, test of proposed method can show contraction
direction of the heart. Health condition of the heart can be detected using sequence of
contraction direction of the heart in normal condition and ten types of heart’s
problem. Proposed method hopefully can give important information as early
warning to physicians about heath condition of the heart.
