ECG systems monitor the heart’s rhythm non-invasively and are used in hospitals and by individuals. Hospital systems require electrodes on various body parts, while personal systems are wireless and can monitor posture and biological data. Some systems can transmit data directly to healthcare providers, allowing for constant monitoring.
An electrocardiography (ECG) system is used to electrically monitor the rhythm of the heart. Provides a non-invasive reading as it does not break skin or enter the body. This medical device is often used by patients whose heart is weak, possibly due to illness, injury or disease. An ECG system is often used in hospitals when medical professionals need to monitor the strength of a patient’s heart. Other types of ECG system can be used by individuals without the assistance of a physician.
The conventional type of ECG system is normally used in hospitals and other healthcare settings. This type of setup requires the patient to wear electrodes on various parts of the body, such as the arms and legs. Most often, the pads are applied in pairs. For example, a patient will wear an electrode pad on both their left and right arms.
Specialist doctors will often use a number of different electrodes as each will monitor the heart from a different angle. By using many electrodes placed on different parts of the body, the most accurate heart rhythm reading can be recorded. The data of each electrode is indicated as a lead.
Many ECG systems are available for people to use without medical assistance. These types of systems often have wireless capabilities. This allows the user to connect a device to himself and monitor heart rhythms without the use of cables or wires. The reading can be viewed on any type of computer on which the appropriate software has been installed. This type of ECG system may also be able to monitor the user’s posture and biological data.
A common ECG system that individuals can use without a physician’s guidance is connected to a mobile device, such as an iPhone®. This system is also wireless. Most models require the use of two different electrodes placed on the chest. The lead number recorded by each electrode can be read on the screen of the applicable mobile device.
Individuals who need to be monitored frequently by health professionals may find ECG systems that transmit data directly to medical specialists to be helpful. A common ECG system that works this way requires 12 electrodes to be placed on the user’s torso. The lead numbers recorded by the pads will be sent directly to the healthcare provider’s computer or mobile device. This system allows the patient to be constantly monitored by the doctor without having to stay in the health centre.
