This impulse starts in the right atrium (right upper chamber of the heart), generated by heart’s own independent “Pacemaker” and then travels throughout the heart tissue through a specialized highly sophisticated system of cells – just like “electrical wires”. Classically this graphic representation of electrical current flowing through the heart is recorded on a moving paper, but nowadays it can be digitally recorded and archived in a computer.Īn electrical impulse (or “wave”) travels through the heart with each heartbeat. This test records the electrical activity of the heart. Electrical Cardioversion for ArrhythmiasĪn ECG (EKG in North America) is also called an electrocardiogram.It is the responsibility of the author to obtain all necessary copyright release permissions for the use of any copyrighted materials in the manuscript prior to the submission.

However, slower heart rate patterns, greater amplitude, and abnormalities in the P, T signal and stretching Q-S distances can be a reference for diagnosing someone with myocardial infarction.
#NORMAL CARDIOGRAPH TRIAL#
This trial also proved that the pattern of human cardiographic signals with myocardial infarction disorders was quite random and and differed from one patient to another.
#NORMAL CARDIOGRAPH SOFTWARE#
MATLAB is one of the software options that can be used in processing cardiographic signals with denoise Wavelet Symlet method, proven to have a fairly high reliability based on qualitative analysis. To eliminate noise on ECG signals, the denoise method using Wavelet Symlet is proven to be better than the Finite Impulse Response (FIR) Hamming Windows filter.
Stages of research include data search, pre-processing, signal processing with the denoise Wavelet Symlet method, and qualitative comparison of cardiographic signal patterns resulting from normal human signal processing with myocardial infarction. For this reason, it is necessary to process the appropriate signal so that the information contained by the signal can be detected easily. On the signal of healthy human cardiography and people with myocardial infarction contain a lot of noise.
