You can ensure itâs delivered by using a tracking number on your receipt. Like a cashierâs check, there is a fee to get a money order. Fees vary widely, but banks and credit unions are usually the more expensive option, charging around $5 to $10. You can get a money order for just a dollar or two at the post office or Wal-Mart.
gina during exercise but no diagnostic ECG changes, or 2) inadequate blood pressure re-sponse (e.g., increase in systolic blood pres-sureG25 mm Hg) in the absence of valvular disease or heart failure, leading to reduced negative predictive value of ETT. 2. Baseline ECG changes leading to reduced specificity (as previously discussed). 3. Rapid resolution of ECG changes. Resolution of exercise-inducedSTsegmentdepressionsinearly recovery (e.g., G 1 min); such changes have re-duced specificity to detect obstructive CAD. 4. Insufficient workload can lead to a lower sen-
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.
