While i'm cycling in the morning my heart rate goes to as up as 175bpm with a average of 150bpm. It's that too dangerous or its normal?

Normal: Everyone has an intrinsic "maximal heart rate" which is different for each of us. During a strenuous workout, you may in fact want to get to 95% of your max heart rate. Unfortunately, without a max heart rate test, you don't know what that is. In any event, if you feel good about the effectiveness of your workouts then there is no cause for concern. ...Read more

Was doing some cardio work outs yesterday for the first time in a while and my heart rate went up to 200 beats a min. Is this normal or dangerous?

Neither: Deconditioned peole can have rapid pulses with excercise. Depending on ones age the heart rate max is 220- the age. So for a 20 year old this can be normal. The heart rate with exercise should improve with persisten excercise as vagal tone improves. One should stopnexcercise if dizzy, lightheaded, chest pain or excessive difficulty breathing and see a doctor to be sure. ...Read more

Is it dangerous if I feel my baby's heart rate goes up a lot when he cries?

Is it dangerous if I feel my baby's heart rate goes up a lot when he cries?

Yes: It's normal for a baby's heart rate to go up when the baby is upset and crying. Babies' hearts beat faster than adult hearts, even when the baby is quiet. A heart rate of 140 is normal for a crying baby and won't hurt your baby's heart. If his heart rate stays fast (eg. Over 180 or 200 beats in a minute) when he's quiet, then you should tell his doctor. A heart rate that fast could mean a problem. ...Read more

Can you exercise so hard that you go over your max heart rate? If so, is it dangerous?

Can you exercise so hard that you go over your max heart rate? If so, is it dangerous?

Exercise and pulse: Young people can easily exceed the recommended pulse rate of (220-age) x 0.7. First off, it's an artificial, but fair estimate for the average person in average condition. Use it as a gauge for measuring cardiovascular fitness. As you get fit, equivalent amounts of exercise should require lesser heart rates; greater exertion can be done with similar heart rates. Don't over think it or overdo it. ...Read more

When I'm at work (nursing) my heart rate is almost always over 110bpm. While exercising yesterday it went up to 198bpm. Suggestions? Dangerous?

Cardiac awareness: Lots of factors influence heart rate. The availability of easy to use monitors has enabled people to pay close attention to these normal reactions. Exercise should cause the HR to go up. Unless heart rate changes are associated with more worrisome symptoms (chest discomfort, shortness of breath, dizziness/fainting) they are unlikely to mean anything bad. ...Read more
