Dangerously Low Heart Rate
Slow heart rate, also called bradycardia, is defined as a resting heart rate (pulse) less than 60 beats per minute. Having a heart rate less than 60 is not necessarily abnormal. In fact, people in good cardiovascular shape have a low heart rate. People with certain heart conditions may take medications which lower the heart rate as one of ...Read more
Not per se: A low heart rate is not in itself dangerous. Many well conditioned athletes have low resting heart rates with excellent cardiac health. A low heart rate that associated with cardiac disease may be an entirely different story. Resting heart rates less than 30 or low rates associated with symptoms always need investigation. ...Read more
Depends: The fetal heart rate is expected to vary before and during labor. When contractions are strong, the stress on baby can alter the rate. A transient slowing during contractions with recovery between is expected. If it goes down low & altering mom's position some doesn't help it return, it can be a sign of fetal distress & lead to an urgent C-section. ...Read more
My five day old newborn had her first checkup, doctor said she has a low heart rate at 90bpm. Me and wife are freaking out! Is this dangerous?
Heart rate: No reason to freak out. Your baby' s heart rate is normal heart rate can vary between 70 and 120 bpm. Enjoy your baby with a clear head. ...Read more
Depends: Slow heart rate resting is not harmful and may indicate an athletic (healthy) physiology. Hr should increase, at least relatively, with exercise - failure to increase is a sign of conduction system disease (chronotropic incompetence). If associated with progressive loss of exercise capacity, treatment may be indicated. This can all be determined easily on a treadmill stress test. ...Read more
Nodal dysfunction: If you have a slow heart beat you should be checked. It is possible you may have dysfunction in your conduction system of the heart. Some medications could be attributing factor. See your md. ...Read more
I assume you mean the baby's heart rate. Drops can be normal, but can also represent a problem that may require that you be delivered immediately. Direct this question to your obgyn right away!
good luck! ...Read more
Depends: If unable to augment the hr appropriately, this would be not beneficial. However if the hr stays low because the person is highly conditioned, then the slow hr suggest a good condition. ...Read more
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. ...Read more
Heart rate: Two main reasons: excellent conditioning or beta blockers on board; there are others less frequent. ...Read more
Depends how slow: A low (or slow) resting heart rate may be entirely normal particularly in highly conditioned athletes. Most people have a slower heart rate when sleeping as well. These slow heart rates likely have no negative health effects. In contrast, there are some individuals who have a dangerously slow heart rate often associated with abnormal heart rhythms (such as 3rd degree heart block) or other diseases. ...Read more
Depends: Some bradycardia can due to medicines called beta blockers, or a natural effect of good conditioning as seen in athletes. However, it can be a sign of serious heart disease impairing the electrical system of the heart. See your health care provider to evaluate the causes. ...Read more
If heart rate is already less than 60, and a beta blocker (pindolol) is to be added, then heart rate willbe further lowered, possibly enough to case side effects or decrease cardiac output.
If the patient has already been fully evaluated, a cardiologist may still add a low-dose beta blocker in some cases, in order to reduce the oxygen demand of the heart muscle. ...Read more
Pacemaker: The pacemaker is likely programmed to stimulate your heart if your intrinsic rate falls below a programmed rate like 60 or 70 beats a minute. If your heart is going 90 on its own, the pacer is just monitoring to see how fast the heart is going and will 'kick in' if your heart slows to under the programmed rate. ...Read more
How do you know if: There is a lower hr in that person? . Two ways, by pulse or by ECG monitor. If there is no pulse anywhere and the person have electrical activity by ECG and there is unresponsiveness, you are in pulseless electrical activity (pea). And CPR need to be started. ...Read more
Cardiologist: If 45 BPM is not your usual heart rate and you're now having chest pains, the main activity you need to do right now is go to an er for emergency evaluation. If this is a chronic state for you, you need to ask your cardiologist about your exercise tolerance. This can be assessed, and depending on your clinical status some form of cardiac rehabilitation may help you. Good luck. ...Read more
I have a low heart rate but I'm overweight? A low heart rate is better than a high heart rate right?
Not necessarily: It depends on how low the heart rate is and whether the heart rhythm is normal or abnormal. A high resting heart rate is more indicative of heart disease or other types of medical problems than a low resting heart rate so long as the low heart rate is not too low. ...Read more
Can a spinal tap cause low heart rate? If not what could cause low heart rate? What am I @ risk of due to having low heart rate? How to gain normalhr
Lumbar puncture: A spinal tap would not normally cause a low heart rate, if you have a persistent low heart rate that is symptomatic a consultation with a cardiologist would be the best route to go. ...Read more
Maybe/maybe not: Pacemakers have a setting for a minimum heart rate. The setting is unique to each individual but commonly is around 50-60. If your heart rate is <50, your pacemaker may not be functioning correctly. Pacemakers should be checked, at least over the phone, every 3 months. Have you had yours checked recently? ...Read more
Varies: They will do an ekg to look for electrical "block" (delayed conduction). He/she'll look at any medicines you may be taking. The doc may want to record your heart rhythm for 24 hours to see how slow you go during sleep. Sometimes treadmill exercise can be a helpful test. There are other, more sophisticated testing that is sometimes necessary. ...Read more
Nature/ Genes: Low blood pressure and low pulse may be normal in people who always have been like that. They are of concern when they change significantly from the baseline BP or pulse. Pulses too low at any point of life (less than 40) are of concern. Athletes develope pulses in the 50s. Medicines may cause bradycardia in the 50s (digoxin, beta or calcium blockers (metoprolol, atenolol, diltiazem, verapamil. ...Read more
Yes maybe: If you get dizzy/lightheaded, feel like you could pass out, you should. Are you on any medications that can slow the heart down. Your heart rate should be above 50 bpm. If not, you may have several different causes, sinsus brady, av block, type 1 or type 2 heart block maybe even type 3 heart block but I doubt this one at your age. Have you doc check med cause first. May need holter and ekg. ...Read more
No: There is no direct correlation or effect of an angiotensin converting enzyme inhibitor with low heart rate. ...Read more
See your doctor: If you are wondering if your heart is causing your dizziness, you would need to know your blood pressure and your heart rate while you are in various body positions. Other questions include do you have chest pain or shortness of breath and what is your normal heart rate and blood pressure? I recommend that you see your doctor to address your question. ...Read more
