An ECG is simply a representation of the electrical activity of the heart muscle as it changes with time, usually printed on paper for easier analysis. Like other muscles, cardiac muscle contracts in response to electricaldepolarisationof the muscle cells. It ...
How to read an electrocardiogram (ECG). Part One: Basic principles of the ECG. The normal ECG This is the first in a series of articles that aim (i) to help readers understand and interpret electrocardiogram (ECG) recordings, and (ii) to reduce some... D Price - 《Southern Sudan Medic...
ECG (electrocardiography) is a method of collecting electrical signals generated by the heart. This allows us to understand the level of physiological arousal that someone is experiencing, but it can also be used to better understand someone’s psychological state. Below we’ll go through the impo...
As a warm up for the rest of this article, you might want to take a gander atToday I Found Out‘s article: “How The Heart Works”. Or, to make a long story short, most healthy hearts pump blood through the body when stimulated by an electrical signal that travels along predetermined...

And if that would be true, then it makes sense to me that Adobe Reader doesn't have the capability of importing an electronic medical chart (to name another example... a .csv file dataset that is being pulled from an ECG database). If that would...
Using ECG with other biosensor measurements can provide a more complete way of understanding someone’s thoughts, emotions, or behaviors. By using the complementarity of each sensor to understand a different aspect of human responses (e.g. by pairing facial expression analysis with ECG to understand...

To understand these variations, we need to look at how each device measures heart rate.The Galaxy Watch and pulse oximeter use optical sensors, technically calledphotoplethysmography (PPG), to detect blood flow changes through your skin.In contrast, the blood pressure monitor usesoscillometric technolo...
