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 in Electrical

A fresh, single AA battery supplies between 1.2 to 1.65 volts, depending on its composition. Nickel-metal hydride and nickel cadmium batteries put out 1.2 volts and are rechargeable. Lithium, zinc-carbon and alkaline batteries put out 1.5 volts but are not rechargeable. Nickel-zinc batteries put out 1.65 volts.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 >
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 >
