A low voltage electrocardiogram result can be caused by a problem in the heart's ability to generate electricity or can be due to the presence of fluid or air in the chest between the electrodes and the heart. Chronic heart diseases, such as cardiomyopathy, can cause low voltage ECGs.Continue Reading
Low voltage ECGs can also be caused by fluid around the heart blocking the electrical signal. Chronic obstructive pulmonary disease can also cause low voltage ECGs due to hyper-inflation of the lungs or pneumothorax. Low voltage ECGs are common after open-beat heart surgery.
If low voltage ECG is a new finding, it may indicate the presence of cardiac tamponade, which is a medical emergency.Learn more about Electrical
A DIAC is a solid-state switch that conducts electricity above a certain breakover voltage limit and is used to switch AC voltage. When a DIAC's breakover voltage is achieved, the voltage across the diode drops and causes an increase in electric current running through the diode.Full Answer >
A GFCI outlet, or ground-fault circuit interrupter, is an outlet that stops electricity from flowing through it if it detects a problem or a ground-fault. The outlet trips, the same as a breaker trips in an electrical panel, as a safety measure.Full Answer >
An electrocardiogram is a type of diagnostic test that is used to determine the presence of problems with the heart's electrical activity, according to WebMD. The test is usually ordered to find the cause of specific symptoms which may be related to a heart condition.Full Answer >
Patients may have an abnormal electrocardiogram result if the heart beats less than 60 beats per minute or more than 100 beats per minute, according to WebMD. In addition, if the heart beat is irregular or if the recorded tracing does not look normal, an abnormal result may be determined.Full Answer >
