At what point does a high heart rate during exercise become dangerous? Would an extremely high heart rate of 250-270bpm be considered dangerous?

At what point does a high heart rate during exercise become dangerous? Would an extremely high heart rate of 250-270bpm be considered dangerous?

Maximum: Maximum predicted heart rate is calculated as 220-age. For a 22 year old the maximum heart rate is therefore 198 bpm. If your heart rate reaches 250-270 during exercise, it would be best to get evaluated.

How would monitoring my heart rate during exercise help me?

How would monitoring my heart rate during exercise help me?

Exercising the heart: Your heart rate during exercise is an insight into how hard your body is working. First off you need to determine your maximum predicted heart rate for your age. This is 220 minus your age. From this number you can figure out your "zones". A good workout zone is 70-85% of the maximum. Talk to your doctor or a personal trainer to figure out what's best for your health and your goals.

What is the medical explanation for low heart rate during exercise?

What is the medical explanation for low heart rate during exercise?

Several: There are several possibilities. If you're a seasoned athlete, it's due to improved stroke volume (blood ejected with each contraction) requiring a reduced heart rate to achieve a given cardiac output (the product of sv and hr). Other possibilities are: medications, vagal reactions, chronotropic incompetence, av nodal block, or sick sinus syndrome. Incidentally, typhoid fever can cause it too.

Can having high LDL levels make it more difficult to lower heart rate during exercise?

What is the safe maximum heart rate during exercise for a 58 year old woman with BMI 36.8?

What is the safe maximum heart rate during exercise for a 58 year old woman with BMI 36.8?

Interesting question: In theory 220- age is maximum heart rate, but I have seen some people exceed this formula, the real question is target heart rate- probably 60-70% of this according to exercise physiology - about 112 for you. If you run a bit higher comfortably, don't worry. As you excercise more your heart rate may drop as you get more fit. Still, you don't have to go that hard to get benefits. Be well!

Would using Claritin (loratadine) d cause rapid heart rate during exercise?

Would using Claritin (loratadine) d cause rapid heart rate during exercise?

Yes, any "D" drug: The "d" in claritin-d, or Mucinex (guaifenesin) - d and others, all stand for decongestant. Decongestants are medications that stimulate the adrenaline system and can cause higher blood pressure and heart rate. While not bad for short time, may cause problems if used chronically. Check with your dr. If you have high blood pressure or heart rhythm problems before using these medications.

I have hypokpp. Is it K related to be unable to increase heart rate during exercise? Is usually accompanied by weakness, no pump, no perspiration

I have hypokpp. Is it K related to be unable to increase heart rate during exercise? Is usually accompanied by weakness, no pump, no perspiration

Yes: If by hypokpp you mean hypokakemic periodic paralysis then yes. The muscle cells lose potassium (k) and cannot contract causing weakness. Hard to increase heart rate. Triggers can be diet related esp by sweet or starchy foods. Too much activity as well as even sleep can be triggers as can some meds. Be sure to have close follow up with your doctor.

How to determine my max heart rate during exercise? I am a 52yr old male ex af patient 2.5yrs ago, following successful catheter ablation procedure.

How to determine my max heart rate during exercise? I am a 52yr old male ex af patient 2.5yrs ago, following successful catheter ablation procedure.

168: Maximum heart rate depends on age using the formula 220-age=maximum heart rate. In your case 100% of maximum predicted heart rate is 168. I recommend 85% of this number which is about 143 bpm. It should not go above 168.

How high should my heart rate go during exercise on 20mg of beta blocker?

How high should my heart rate go during exercise on 20mg of beta blocker?

Ask Ur cardiologist-: -2 B on the safe side. Usually it's around 150-160BPM above Ur resting pulse. It is important for U 2 use Ur brain & when U feel it's 2 fast or U get short of breath, slow down or stop & rest, take Ur pulse whenever this happens & report it 2 Ur cardio guy.

What does it mean if my heart rate was really high during exercise and stays at 110 over an hour and a half after exercise? Is it anxiety?

What does it mean if my heart rate was really high during exercise and stays at 110 over an hour and a half after exercise? Is it anxiety?

LargestPossibilities: =anxiety/fear/pain &/or congestive heart failure. Heart rate controlled by brain. Like rest of body, heart follows orders from brain (many cycles/second). Sensors from heart, blood vessels, rest of body provide extensive feedback to brain: a complex Soul? Mind? Brain? Body integrated system which allows life, despite only partially understood.

My heart rate is elevated during exercise and after? Athlete, should be harder to reach 190's than it is. Pounding, SOB. HR at 135 13 min after finish.

My heart rate is elevated during exercise and after? Athlete, should be harder to reach 190's than it is. Pounding, SOB. HR at 135 13 min after finish.

Be seen: You should be seen just to rule out any underlying congenital cardiac abnormality; which can affect even young apparently healthy athletes.

If somebody has high heart rate (>90 at rest) it is very easy to hit the max HR during exercise even moderate. How safe is to exercise at that level?

If somebody has high heart rate (>90 at rest) it is very easy to hit the max HR during exercise even moderate. How safe is to exercise at that level?

Slowly increase...: Lack of conditioning can lead to a HR that increases rather quickly with exercise. Slowly increasing the duration & exertion with exercise - and being consistent with exercise will help lead to a lower resting HR and a slower increase. The max HR recommendations are safe; however, it isn't easy to maintain them for a length of time that would be beneficial. Build up your tolerance.

What makes heart rate increase during exercise besides epinephrine?

My heart rate is over the 100. I never exercise and get fatigued pretty soon during exercise since I was a child. Why is my heart rate this high?

Out of shape?: Probably because you're out of shape. Talk to your doctor about a safe exercise regimen. It usually starts with regular fast walking.

Heart Rate (Definition)

Heart rate is a measurement of the number of times a person's heart beats in one minute. Normal heart rates vary with a person's age and with excitement and exercise. Abnormal heart rates are too slow, too fast, and/or irregular (too much ...Read more
