What is ECG in medical terms?
An electrocardiogram (ECG) is a medical examination that detects cardiac (cardiac) abnormalities by measuring the electrical activity caused by the heart when it contracts. The device that records the patient's ECG is called an electrocardiogram.#N#The electrocardiogram records the electrical activity of the heart muscle and displays this data as a trace on screen or on paper. These data are then interpreted by a practicing physician.#N#The healthy heart ECG has a distinctive shape. Any change in heart rate or damage to the heart muscle can alter the electrical activity of the heart so that the shape of the electrocardiogram changes.#N#Your doctor may recommend an ECG for people who may be at risk for heart disease because of a family history of heart disease or because they smoke, are overweight, have diabetes, have high cholesterol or high blood pressure.#N#When Doctors can prescribe an ECG if a person has symptoms such as: 1 chest pain 2 shortness of breath 3 dizziness 4 faint or 5 fast or irregular heartbeat (palpitations).
What is a 12 lead ECG?
A 12-lead ECG is an effective clinical decision-making method and can provide a wealth of information such as diagnosis of developing MI; detect life-threatening arrhythmias; long-term effects of persistent hypertension; or acute pulmonary embolus symptoms. Unlike cardiac monitoring, the 12 lead ECG displays the heart's 3-dimensional electrical activity captured from twelve separate leads or points of view. It gives the entire photo. So it's also called an ECG system multichannel. Most of the 12 channel ECG machine is known to print on A4 size paper ECG sheet. And the report is broad and low.

How to measure electrical activity of the heart?
The electrical activity of the heart can be measured on the surface of the skin – even as far from the heart as on your arms or legs. The standard “12-lead ECG” uses a total of ten electrodes: six on your chest, and then one each on your lower arms and calves. If there is too much body hair, these areas are shaved first; other than that, no preparation is needed. These electrodes are connected by cables to an ECG machine. The machine converts the signals it receives into an ECG graph and saves it. Some machines can also print the graphs out.
How does a Holter monitor work?
Holter monitor: The electrical activity of the heart is typically recorded over a period of 24 hours. Three or four electrodes are attached to your chest, and a small recording device is worn on a belt or hung around your neck. The ECG data are then transferred to a computer later on at the doctor's office for analysis. To do this, the doctor also needs information about your daily schedule (like unusual events, physical activity and sleep). A Holter monitor may be used if, for instance, you only have an irregular heartbeat some of the time and it doesn't show up in a “normal” ECG.
How do nerves communicate with each other?
Our nerve and muscle cells communicate with each other using electrical and chemical signals. Regular electrical signals also control our heartbeat. These signals are sent by a group of cells in the right atrium of the heart known as the sinoatrial node (SA node), and they spread through the heart muscle tissue as tiny electrical impulses. This causes first the atria and then the ventricles of the heart to contract. The way that these signals spread through the heart can also be measured on the surface of our skin. An ECG measures these changes in electrical signals (or, in fact, voltage) on different areas of skin and plots them as a graph. The resulting ECG graph is called an electrocardiogram.
What is the first peak of the ECG?
If the heart is beating steadily, it will produce the typical ECG pattern: The first peak (P wave ) shows how the electrical impulse (excitation) spreads across the two atria of the heart. The atria contract (squeeze), pumping blood into the ventricles, and then immediately relax. The electrical impulse then reaches the ventricles. This can be seen in the Q, R and S waves of the ECG, which is called the QRS complex. The ventricles contract. Then the T wave shows that the electrical impulse has stopped spreading, and the ventricles relax once again.
What is IQWiG health information?

What is the ECG of the heart?
ECG records the electrical activity generated by heart muscle depolarizations, which propagate in pulsating electrical waves towards the skin. Although the electricity amount is in fact very small, it can be picked up reliably with ECG electrodes attached to the skin (in microvolts, or uV).
How does a PPG clip work?
As the blood pulses into the tissue, more light is absorbed – as the blood flows away from the tissue, more light is reflected. PPG clips use dry sensors and can be attached much quicker compared to ECG setups, making the device relatively easy to use, and a little bit less bothersome for participants.
What does HR mean in a heartbeat?
