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.
Another pattern (ST depression) suggests ischemia - or a lack of blood supply to part of the heart again is suggestive a partial blockage. A resting ECG may be normal despite a blockage. Contrary to popular belief a NORMAL ECG does NOT exclude blockages. The use of excercise (treadmill) or certain medications to increase heart rate (work load on the heart) increase the likelyhood that changes will be found suggesting blockage.
