The electrocardiogram or ECG machine may make a series of cardiac abnormalities and is one of the most valuable tools in any healthcare facility seen. The portability of these devices, is large even in small clinics and nursing home environments.
There are companies that rent, lease or sell this product, either new or used, and ensure their accuracy.
How does a EKG machine
The patient simply lies on a table, while tentwelve electrodes (wires) in some areas of the body, chest, arms, underarms and legs are attached. These electrodes can detect electrical impulses generated by the human heart, then transfer to an ECG machine, which then gives a graph or plot shows the results of these electrical impulses. The process can in less than five minutes and provides much valuable information rate. These tests are very thorough,exactly, and are relatively inexpensive.
A typical ECG tracing, the following information:
Heart Rhythm Heartbeat Abnormalities in the activity center (which shows abnormalities that occur on the heart itself) Indicates whether there is any form of coronary artery disease Can tell if it was a heart attack Determines whether the heart muscle thickens abnormally increased
How valuable are the result of an ECG
If there is evidence of heartIllness or problems in the walls of the heart muscle, and will appear in the curves show, there are potential problems that should be examined further by a cardiologist.
If the EKG machine detected problems in the heart as a thickening of the walls, further tests may be ordered, probably including the use of an echocardiogram. If the patient complains of blackouts, this can change the outcome of the electric models and some form of heart disease areDisease.
ECG testing has its limits
An ECG may reveal only assess the heart rhythm, and during the testing process is ongoing, so if the heart rhythm abnormalities only intermittently, which can not be displayed because the patient is tested. There are sometimes involved in false negative test is conducted at the ', so that no indication of heart problems at this particular time. The opposite can happen, and create false alarms due to peculiarities of the device orTest leads. The electric current is simply incorrect values (usually because of operator error in the positioning of the connections).
The differences in ECG devices available
There are various patterns of ECG machines for sale or rent, the result of twelve car with three channels, which provide an independent and includes a built-in printers and screens for reading. There are also twelve-channel unit with a maximum of twelve leads per channel or page. Somehave an LED screen, which provides immediate information.
Some of these are light, trolley on wheels, then it portable and easy to move. It must provide transportation, however, the machine will continue to be employed to give accurate measurements.
