The heart is an organ that circulates blood in the body through its rhythmic rhythm. The heart follows a certain “heartbeat” pattern that is regulated by electrical signals generated in the heart area.
Signals are mainly generated by the sinus node (SA node, in the right atrium) and by the atrioventricular node (AV node, in the lower ventricle). To gain more details about the ECG you can also view the product online.
In the event of a malfunction, the heart rate is checked by the ECG device and the information is recorded. ECG measurements help cardiologists to interpret the patient’s heart condition.
ECG readings appear in the form of a graph called a PORTS or waveform graph. The entire unit consists of the P wave, QRS complex and ST wave, which follow each other in sequence.
The first wave shows the contraction of the atria (front of the heart), the second part shows contraction of the ventricles (lower chambers of the heart), while the ST wave shows relaxation or expansion of the ventricles when filled with blood forming the atria.
The various interconnected waves indicate the contraction and expansion of the atria and ventricles as they regulate blood flow to the heart.
Information is collected by placing electrodes on various parts of the body, such as the arms and legs. About 10 to 12 of these points are connected to an electrocardiogram (ECG/EKG) device.
