What is ECG?

 

ECG stands for ElectroCardioGram, It's a test that records the electrical activity of your ticker through small electrode patches that a technician attaches to the skin of your chest, arms, and legs, ECGs are quick, safe, and painless.

ECG is recommended if a person is experiencing symptoms such as:

  1. chest pain
  2. shortness of breath
  3. dizziness
  4. fainting, or
  5. fast or irregular heartbeats (palpitations).

What can ECG detect?

  1. Enlargement of the heart
  2. Congenital heart defects involving the conducting (electrical) system.
  3. Abnormal rhythm (arrhythmia) – rapid, slow or irregular heartbeats.
  4. Damage to the heart such as when one of the heart’s arteries is blocked.
  5. Poor blood supply to the heart.
  6. Abnormal position of the heart.
  7. Heart inflammation – pericarditis or myocarditis.
  8. Cardiac arrest during emergency room or intensive care monitoring
  9. Disturbances of the heart’s conducting system
  10. Imbalances in the blood chemicals (electrolytes) that control heart activity
  11. Previous heart attacks.

So the ECG signal is very important in general, and especially for older people and they should check their heart regularly.

 

What These Numbers Mean? And What are the normal range?

 

BPM: Beats Per Minuit

For adults 18 and older, a normal resting heart rate is between 60 and 100 BPM

PR Interval (ms)

The PR interval is measured from the beginning of the P wave to the beginning of the QRS complex. This interval reflects the time the electrical impulse takes to travel from the sinus node through the AV node.

Normal Range: 120 to 200 ms.

QRS (ms)

The QRS complex represents the rapid depolarization of the right and left ventricles. The ventricles have a large muscle mass compared to the atria, so the QRS complex usually has a much larger amplitude than the P wave.

Normal Range: 80 to 100 ms.

QT interval Or QTC (ms)

he QT interval is measured from the beginning of the QRS complex to the end of the T wave. Acceptable ranges vary with heart rate, so it must be corrected to the QTc by dividing by the square root of the RR interval.

Normal Range: Less than 440 ms.

 

 

What are the hospital level Lead? And what are D-Heart Leads?

The Hospital Monitors has12 Leads, which are necessary in the ER or OR.

When Diagnosing, you can get a diagnose with 3 Leads device, But D-Heart has 8 Leads diagnose ability.
and that's what gives it the advantage between other products, and it is concidered a Hospital Level Device
