What are the different types of ECG devices?
Electrocardiogram (ECG) is a test that checks the heart's electrical impulses. The ECG machine is not one tool, but several pieces of equipment that cooperate on the detection and recording of heart activity. The machine reads the heart of the pulses and translates them into a chart in the style of the scheme on specially designed paper strips. ECG equipment includes a set of lead wires. Most machines use 10 or 12 lines. At the end of each, the wires look like plastic wires with small metal discs. The discs are designed to pick up electrical pulses of the heart. Each disc has a lead connected to one side and the other side is flat and is ready to accept a sticky paste that attaches the disk to the body when applied.
Most ECG devices includes a writing keyboard that allows health care providers to enter the patient name and other data, which will then be printed on the test strip. The ECG device is usually portable and mounted on the rack on the kolecht is easily moved todifferent investigative rooms as needed. The main machine also has an installed alarm to alert the test provider to test problems such as a line that is not properly connected to the patient's body.
Test paper is another tool used in the ECG device. The test paper is designed to width so that it falls neatly into the main machine. As the ECG test occurs, the machine transmits the heart rate data to the ink paper. The background of the test paper strip is usually colored pink, blue or green to make it easier to illustrate the peaks and valleys of electrical pulses diagrams. When the pulses are recorded, the belt paper is pushed through the machine and creates a long, narrow diagram of the heart activity.
Another ECG device is not part of the actual ECG machine, but it is necessary for the test. Testing table or chair is used for patients during the test process whorice usually takes less than a minute. In some cases, the ECG machine is constantly connected to the patient to constantly monitor the heart rate, in which case most patients lie in bed. The adhesives of the sticks are usually used to connect electrode disks to the patient's skin. Alcohol friction is often used to remove adhesive from the skin after the test is completed and the electrodes were removed.
