The Walking Stick with Heart Attack Detection is equipment
that is used daily to indicate heart
condition, to detect heart attack and to
call for emergency help. It was designed specially to help senior citizens and patients
with heart disease. This project is based on the previous project “Wireless
Heart Attack Detector with GPS”
The National Heart, Lung, and Blood
Institute states that “more than a million
persons in the U.S.
have a heart attack and about half (515,000) of them die in each year. About one-half of those who die do so within
1 hour of the start of symptoms and before reaching the hospital”. A heart attack
happens to a person when the blood flow and oxygen supply to heart muscle is
blocked, and it is mostly caused by the Coronary Artery Disease (CAD) . CAD occurs when the
arteries that supply blood to the heart muscle (coronary arteries) become
hardened and narrowed . It often causes irregular heart beat or rhythm by
blocking blood stream. The National
Heart, Lung, and Blood Institute suggest that “everyone should know the warning signs
of a heart attack and how to get emergency
help”.
The
symptoms of heart attack can be detected by observing electrocardiogram (ECG)
waveform. An ECG is an electrical recording of the heart and is used in
the investigation of heart disease. An electrical impulse initiates muscle
contraction, which results in heart beating. The spacing between pulses
provides a measure of the heart’s rhythm, whereas the height of the pulses is
an indicator of pumping strength. By observing the ECG waveform, the heart
condition of the patients can be explained by doctors.
The ECG Library shows many samples
of abnormal ECG waveform, and they are mostly collected from aged people who
are more than 55 years old. The senior citizens are more prone to have
heart attack than young people. The Walking Stick with Heart Attack Detection
is specially designed to help the senior citizens who need walking aids by
walking sticks and have the most possibility of heart attack. The walking stick
is used as detection unit and as the medium asking for medical help.
