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
Warning lights, unpredictable engine performance and dimming or pulsating lights are all signs of a faulty voltage regulator. A number of symptoms can develop if the voltage regulator fails to deliver sufficient voltage. Warning lights may not inform the operator of such a failure until it is too late, so it is important to be aware of the associated issues.Full Answer >
CircuitsToday.com, ElecCircuit.com and ElectroSchematics.com have voltage regulator diagrams available. Schematics shown include those for floating regulators, switching regulators, dual voltage regulators, adjustable regulators and conversion regulators. All the sites have schematics for the popular National Semiconductor LM series, including the 1758 A, 2575, 2577, 309 and 317 models.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 >
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 >
