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.Know More
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
The electrical voltage in Mexico is 110-120 volts, the same as in the United States. While the sockets are the standard two prong versions that are found in the United States and Canada, adapters may be required for certain equipment.Full Answer >
The standard mains voltage used in the United States is approximately 110 to 120 volts, according to Georgia State University's physics department. Depending on the power load, it can vary between these two measurements.Full Answer >
To use a voltage tester, place both probes of the tester on each wire or connection point. The light on the housing of the tester glows if the component that is being tested is receiving electricity. The light does not glow if there is no electricity flowing into the component.Full Answer >
Thirty-amp fuses can handle both 120 and 240 volts, which are the common voltages in the United States. Fuses or circuit breakers prevent too much current going through a circuit and reduce the risk of fire.Full Answer >
