This week Consumer Reports released news that arsenic was found in brown rice, white rice, rice breakfast cereals, organic rice baby cereal, and other rice productsââmany at worrisome levelsââin tests they performed.
First-degree heart block. First-degree AV block is defined as a PR interval longer than 0.2 seconds. Each atrial activation leads to a ventricular activation with a 1:1 correspondence.
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.
