When hr goes down to 39 in sleep, is it dangerous? When is a low hr a problem? Why don't u want people taking beta when they have low resting hr?

When hr goes down to 39 in sleep, is it dangerous? When is a low hr a problem? Why don't u want people taking beta when they have low resting hr?

39 with sleep: All people have slow HR during sleep. 39 during sleep is harmless and not unusual. Pauses in the heart rate of >5 seconds generally require a pacemaker. Pauses in the HR that cause people to pass out (or nearly pass out) also require a pacemaker. HRs in the 30s during sleep never cause symptoms and don't require treatment. ...Read more

If u already have low resting hr but need to take metoprolol 25 mg, is it fine as long as u don't have symptoms? Wil the heart stop? My doc said its ok

Yes: It is ok to take it as long as you don't develop symptoms. Your heart will not stop because of metoprolol. Symptoms you should be cautious about are lightheadedness, dizziness and fainting. Also 25 mg of metoprolol is a low dose and shouldn't cause you any problems. Always follow-up with your dr. ...Read more

Had ECG for low resting HR 3 months ago, normal result. Today HR was 39 on waking. Exercise 1x/week - 20min jog. I eat healthy, BMI 22. Is it normal?

Had ECG for low resting HR 3 months ago, normal result. Today HR was 39 on waking. Exercise 1x/week - 20min jog. I eat healthy, BMI 22. Is it normal?

Low resting HR: The best answer is perhaps, assuming that the EKG is otherwise normal, then can keep track of your heart rate. It is not uncommon for your heart rate to be lower when you wake up. As long as it increases during the day and with activity, then it is likely ok. You can check it when you are exercising to see if you are in the training zone. ...Read more

Hi Oskar: Something's up. If your HR remains >100, an EKG should be done to confirm normal mechanism. If nl, then a search for non-cardiac causes is indicated: fever, pain, anxiety, infection, hemorrhage, stress, dehydration, etc. If your HR has returned to normal, I wouldn't pursue it. ...Read more

I'm a 32yo female who works out 6 days/week., however not an elite athlete. My resting HR is 40. Is that too low?

Only if you've sympt: Though you aren't an elite athlete, exercising 6x per week, religiously, is impressive. Does each session last 30+ min? I suspect you are fit but only an exam will confirm that. If you are fit, a HR of 40 is not unusual. Unless you are passing out, having trouble with vision or balance, or other symptom from the low heart rate, I'd say it's not too low. Talk to ur doctor, though, who knows yu best ...Read more

My resting hr is 85-95. When I do 5 min of low impact zumba my hr goes to 175+ & I feel faint im 28 & 458lbs what should my max hr be when exercising?

Evaluation: Exercise is great way to start loosing weight, but considering your possible lack of endurance you need to approach it slowly, preferably under supervision of personal trainer or at least guidance. Complements on your effort, please see you doctor to rule out underlining heart problems. With time your heart rate will adjust, you need more endurance. Do it safe. ...Read more

My resting HR at night when laying in bed is 54! Is that to low? I eat very healthy. I don't exercise, but im always on my feet & I use stairs @ work

Low rest heart rate: You are fairly young and a resting heart rate of 54 is not necessarily abnormal even though it is lower than the usual 60-80 range. If your energy level is otherwise Ok and you have no other complaints it may mean nothing. Heart rate does drop with sleep and it could also be a remote sign of sleep apnea ...Read more

I'm athletic/exercise daily. Resting HR is usually 48-52 bpm. Resting breathing rate is pretty low (10 breaths/minute), but I feel fine. Is that ok?

Athletic vital signs: For a conditioned athlete, heart rate in the upper 40's-50's is likely normal.

Some professional athletes such as bicyclers can have resting heart rates in the upper 30's.

Respiratory rate of 10-12 is normal range for athletes. ...Read more

Metoprolol: This medicine is generally not given if a patient has a heart rate less than 60, has a significant heart block, or has cardiac failure. Of course, this depends somewhat on why it is being given. Using it in hypertension will have different requirements than using if for a heart attack. ...Read more

Heart rate has been high min 90+ at rest. Medication change from felodipine to ramipril, now HR low 48-53 at rest. (not athlete) Is this a concern?

Heart rate: There is a difference between these drugs in the amount of arterial vasodilation. The Felodipine can be expected to dilate arteries more than ramipril and have more secondary heart rate increase associated with it. Likely you don't have a concern. ...Read more

If all of your: Testing is normal and you have no symptoms, there is no reason to be concerned by a HR of 54. Many well trained athletes have resting heart rates in the 30s. The key is symptoms. If there are none then there is no concern. Bradycardia is a descriptive term. Symptomatic bradycardia is a clinical condition requiring treatment. ...Read more

22 got post orthostatic tachycardia syndrome. My heart rate sometimes is 52-58 resting but usually 60-80. Is the low hr dangerous? See tests on profi

HR not dangerous: Postural orthostatic tachycardia syndrome (pots) is characterized by tachycardia, elevated heart rate, on standing with decrease in blood flow to the brain. A low heart rate is not part of this diagnosis.

Some pts have associated vaso-depressor syndrome which can cause a low BP and sometimes a low heart rate (cardio-inhibitory).

Your hr is not in a dangerous range unless symptoms present. ...Read more

Dizziness and a: Pounding sensation in the head may be from an excessively elevated blood pressure. Sometimes, elevated BP can cause a reflex slowing down of the heart rate. These may be signs of serious complications of midodrine. Contact your doctor ASAP. If s/he can't be reached, go to your nearest medical facility. Tell them you're taking midodrine. At minimum, you need vital signs, clinical exam & an EKG. ...Read more

For example, professional bicyclers can have resting hr in the upper 30's per minute.

The exception to the low resting heart rate comments above would be if you have symptoms from low heart rate or if your heart rate cannot raise normally with exertion. These people require evaluation to see if they need a pacemaker. ...Read more
