The system “LabVIEW based ECG signal
acquisition and analysis” is developed to assist patients
and doctors in health care. An arrhythmia is an
abnormal heart rhythm. It may be so brief that it
doesn’t change the overall heart rate, but it can cause
the heart rate to be too slow or too fast. When
arrhythmias are severe or last long enough, the heart
may not be able to pump enough blood to the body. This
can cause the patient to feel tired, lightheaded or may
make him pass out. It can also cause death. Before
treatment, it’s important for the doctor to know where
an arrhythmia starts in the heart and whether it’s
abnormal. An electrocardiogram (ECG) is often used to
diagnose arrhythmias. “LabVIEW based ECG signal
acquisition and analysis” is meant to acquire ECG
signals from the patient and analyze it to detect and
classify its anomalies and abnormalities. This is achieved
by extracting amplitudes and durations of parameters of
ECG waveform such as P wave, QRS complex, RR
interval, and PR durations. These parameters are
compared with the normal values to determine the type
of abnormality- Tachycardia or Bradycardia. The
database of the patient is maintained for further use by
the doctor.
The objective of LabVIEW based ECG signal
acquisition and analysis aims at acquiring and analyzing
temporal parameters of ECG signal such as P wave,
QRS complex, RR interval, PR durations and
amplitudes of the P wave, ST wave, identification of
cardiac arrhythmia using LabVIEW. The research work
has helped us to explore various features of LabVIEW
like signal processing and automated database
generation.
