What is an ECG?

What is an ECG Smartwatch?

As mentioned earlier, ECG or electrocardiogram is a diagnostic procedure that detects any heart disease, including a heart attack. When an electric shock is created in the SA node of the atrium, the upper chamber of the heart, the heart starts beating. This electrical energy is delivered to the ventricle, the lower compartment of the heart.

Every time the heart beats, a minimal electrical impulse is delivered to the skin. The ECG machine tracks this and analyzes this electrical activity for heart abnormalities. This electrical activity or changes in the ECG can be a serious sign of heart problems. In hospitals, a 12-lead ECG machine is used to collect ECGs.

You can give your doctor a lot of information about your heart health, such as Irregular heart rate, Heart block, Heart attack, Ventricular fibrillation, Atrial fibrillation, and more. However, recording ECG at home was not accessible until the introduction of the latest wireless wearable FDA-approved ECG smartwatches.

The smartwatch can detect and alert you to an abnormal heartbeat (cardiac arrhythmia) even if it doesn’t recognize a heart attack. This will help you get medical attention just before further complications develop.

If the machine warns your ECG of atrial fibrillation (AFib), you should seek medical attention immediately.

Now let’s move to our list mentioned below.
