Water reuse can reduce the amount of freshwater diverted from sensitive ecosystems, as well as the amount of wastewater â and the pollution it carries â discharged to waterways. In the case of nonpotable reuse, it means avoiding the use of precious potable water where that level of quality is not required. Because of nutrients retained in water when it is not treated to drinking water standards, irrigating with recycled water can reduce chemical fertilizer use.
An abnormal EKG can mean many things. Sometimes EKG abnormalities are a normal variation of a heartâs rhythm, which does not affect your health. Other times, an abnormal EKG can signal a medical emergency, such as a myocardial infarction (heart attack) or a dangerous arrhythmia.
Best Answer: ECG (electrocardiogram) is a test that measures the electrical activity of the heart. The heart is a muscular organ that beats in rhythm to pump the blood through the body. The signals that make the heart's muscle fibres contract come from the sinoatrial node, which is the natural pacemaker of the heart.
