What is ECG/EKG(Electrocardiogram)?

How Does An ECG Work In A Smartwatch

During an electrocardiogram, your heart’s electrical activity is recorded. Heart disease is quickly detected and monitored with this painless test.

ECG is one of the fastest and the simplest tests and is done by placing electrodes at certain essential spots of the body, including your chest, legs, and arms.

Using the lead wires, the electrodes are connected to an ECG machine. This process provides you with your heart’s electrical activity, which is then measured, analyzed, and printed out.

Remember, during an ECG, no electricity is sent into your body. Electrical impulses help keep blood flowing effectively in the heart by coordinating contractions of different parts.

An ECG test provides a lot of essential information to the doctor. This information includes:

  • Fast heart rate (tachycardia)
  • Slow heart rate (bradycardia)
  • Heart rhythm
  • Heart-rate irregularities
  • Heart attack
  • Heart block
  • Atrial fibrillation
  • Ventricular fibrillation

Until modern wireless ECG devices became available, it was impossible to record your ECG at home. However, a smartwatch can alert users of abnormal heart rhythms (cardiac arrhythmias), but it cannot recognize a heart attack. 

This allows you to get medical attention as soon as possible before any further complications arise.

What Is An Atrial Fibrillation?

How Does An ECG Work In A Smartwatch

Atrial fibrillation (AFib) is an irregular and sometimes very rapid heart rhythm (arrhythmia) that may lead to blood clots in the heart. In addition to stroke and heart failure, A-fib increases the risk of heart-related complications.

The symptoms of Atrial Fibrillation are fatigue, chest pain, shortness of breath, etc., and are caused by Lung diseases, Sleep apnea, high blood pressure, heart attack, etc.

What Is A Ventricular Fibrillation?

Fibrillation of the ventricles is a type of abnormal heart rhythm (arrhythmia). In ventricular fibrillation, the lower heart chambers (ventricles) twitch (quiver) uselessly due to disorganized heart signals. 

Consequently, the heart does not pump blood to the rest of the body. The most common symptom of ventricular fibrillation is collapse and loss of consciousness.

How Does An ECG Work In A Smartwatch?

ecg smartwatches

Smartwatches record an ECG by creating an electrical circuit in the wearer’s body. To do this, the watch uses the heart rate monitor on the back of the case, which is pressed against the wrist.

Using a finger from the opposite hand, the wearer touches the front or side of the case. Most ECGs are completed in 30 seconds, and the collected data is sent to a smartphone app.

This app allows users to view, store, and forward their data to a doctor, if necessary.

A smartwatch with ECG capabilities can only detect irregular heart rates and atrial fibrillation. You cannot gain an in-depth understanding of your heart health or cardiac diseases from ECG smartwatches.

ECG Smartwatches have PPG sensors that sense electrical pulses that produce a heartbeat.

Accuracy Of ECG Smartwatch

If you are going to buy an ECG smartwatch, you should go with that smartwatch approved by the FDA (Food and Drug Administration).

ECG smartwatches that are FDA-approved are clinically validated to be accurate. FDA tests the device profoundly and thoroughly for its performance and accuracy. This makes it difficult to get FDA approval.

The ECG smartwatches are very convenient because these smartwatches allow you to take multiple ECGs directly from your wrist. These smartwatches are helpful because they keep you alert and save you from significant complications.

Pros
  • Convenient
  • Easy to use
  • It doesn’t use cables and wires
  • Time-saving
  • Detects Atrial Fibrillation
Cons
  • Doesn’t detect heart attack
  • Expensive
  • Can’t replace medical devices.

Temperature Sensor

Signals from this sensor are used to measure temperature. When it detects a temperature change, the sensor produces an electrical voltage or resistance.

  3. Thanks for your text. I would also like to say that the health insurance agent also works for the benefit of the coordinators of your group insurance plan. The health insurance professional is given a listing of benefits looked for by an individual or a group coordinator. What any broker will is seek out individuals or perhaps coordinators that best match up those needs. Then he provides his recommendations and if all sides agree, this broker formulates a binding agreement between the two parties.
