heart rate monitor

LAS VEGAS — In multiple gestations, dont rely solely on the mothers perception of how the fetuses are positioned when monitorig fetal heart rates, Patricia M. Witcher, a registered nurse clinician, advised at a conference on fetal monitoring sponsored by Symposia Medicus. An ideal way to identify each fetus before heart rate monitoring would be to use ultrasound, but thats not realistic because most people who initiate monitoring dont do ultrasound, said Ms. Witcher, a nurse at North-side Hospital in Atlanta who specializes in labor and delivery and high-risk obstetrics. The best way to identify each fetus is by doing simultaneous monitoring and looking for divergence of fetal heart rate tracings. Thats really the only way we have of ensuring that we have a heart rate for each fetus, she said.
Exercise shouldnt be based on the distance traveled, the amount of time involved or the physical workload; it should be controlled by the degree of physical effort as measured by physiological signs, especially pulse rate. The best way to monitor how fast your heart is beating is a heart rate monitor, which usually consists of a strap worn across the chest that sends an electronic signal to a wristwatch-like device that converts the signal into beats per minute. These monitors enable you to adhere to an exercise program based on heart rate by giving you immediate, continuous and reliable feedback. You are thus less likely to cross the line between healthy exercise for aerobic fitness (a target heart rate of 50 to 90 percent of maximum; see chart) and risky stressful exercise. You will also know if youre not training hard enough to get the full benefits of your efforts, since your workout will be more effective if you maintain a certain pulse rate within your target heart rate zone. Training below the minimum intensity level, youll burn mostly fat and wont see much improvement in aerobic capacity. Above the 90-percent level, youll build up lactic acid; that level of training will make you more susceptible to injury if youre not a highly-conditioned athlete.
