Question

Full research about the biological human signals (ECG, EMG, EEG) time domain and frequency domain analysis (showing all the calculations, diagrams, graphs, wave signals, simulation or a design, Matlab wave, or signal) basically anything related to this topic. (1000 words)

Answer 1

• ECG: An electrocardiogram records the electrical signals in your heart. It's common and painless test used to quickly detect heart problems and monitor your heart's health.
• Electrocardiograms also called ECG or EKGs are often done in a doctors office, a clinic or a hospital room. ECG machines are standard equipment in operating rooms and ambulances. some personal debices, such as smart watches, offer ECG monitoring.
• If your electrocardiogram is normal, you may not need any other tests. If the results show an abnormality with your heart, you may need another ECG or other diagnostic test, such as an echocardiogram. Treatement depends on what causing your signs and symptoms.
• Heart rate: Normally,, heart rate can be measured by checking your pulse. An ECG may be helpful if your pulse is difficult to feel or too fast or too irregular to count accurately.
• Heart rhythm: An ECG can show heart rhythm irregularities. These condition may occur when any part of the heart's electrial system malfuctions. In other cases,, medications, such as beta blockers, cocaine, amphetamines.etc.
• Heart attack: An ECG can show evidence of a previous heart attack or one that's in progress.
• Inadequate blood and oxygen supply to the heart: An ECG done while you're having symptoms can help your doctor determine whether chest pain is causedby reduced blod flow to the heart muscle, such as with the chest pain of unstable angina.
• Structural abnoramalities: An ECG can provide clues about enlargement of the chambers or walls of the heart, heart defects and other heart problems.
• Heart rate can be easily calculated from the ECG strip:
• When the rhythm is regular, the heart rate is 300 divided by the number of large squares between the QRS complexes.
• For example: if there are 4 large squares between regular QRS complexes, the heart rate is 75 (300/4=75)
