Detection and analysis of the designed circuit for ambulatory ECG electrical characteristic points

The heart is the motor of the human body, and the cessation of heartbeat signifies the end of life. Numerous cardiac pathologies such as arrhythmia, myocardial infarction, and cardiac hypertrophy occur. Electrocardiography (ECG) devices are typically required to examine the heart in hospitals. Physicians can use subtle differences in ECG signals to determine whether a patient has a heart disease. Thus, this study designed an ambulatory ECG circuit and applied software to determine the characteristic points of the QRS complex.
