   Abnormal heart rhythms and asystole are possible complications of hypermagnesemia related to the heart. [8] Magnesium acts as a physiologic calcium blocker, which results in abnormalities of the electrical conduction system of the heart. [citation needed] Consequences related to serum concentration: [9]: 281 4.0 mEq/L – Decreased reflexes

   With a maximal stress test the level of exercise is increased until the person's heart rate will not increase any higher, despite increased exercise. A fairly accurate estimate of the target heart rate, based on extensive clinical research, can be estimated by the formula 220 beats per minute minus patient's age.
