Can I Die From Bradycardia If I Ignore It
Anything is possible: But it's not likely. Bradycardia is defined as a heart rate <60. Heart rates of >50 are well tolerated by everyone. Heart rates of 40-50 during wakefulness sometimes cause fatigue. Sustained heart rates of <40 usually cause unacceptable fatigue and breathlessness. Pauses of > 3-5 seconds may cause dizziness. Pauses of > 5 seconds often cause blackouts. Pauses of > 2 minutes may cause death. ...Read more
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
Bradycardia: Bradycardia, in adults (not in children) is defined as heart rate slower than 60 beats per minutes. It can be perfectly normal in people who are athletic. For example, marathon runners can have resting heart rate in 40s or even lower. It is, generally, pathological, if it leads to symptoms of dizziness, lightheadedness or fainting. If it causes extreme symptoms, a pacemaker is needed. ...Read more
It depends: Bradycardia indicates that the heart rate is too slow (< 60 BPM in adults). It may be associated with a normal electrical impulse (such as sinus bradycardia in a well-trained athlete or during sleep) or an arrhythmia (abnormal electrical impulse). Some of the more common abnormal rhythms associated with bradycardia include atrioventricular block, sick sinus syndrome, and junctional rhythm. ...Read more
HR < 50: Bradycardia is defined as heart rate less than 60 bpm. I don't know if there is a formal definition of severe bradycardia, but I would consider bradycardia severe if the heart rate was less than 50. ...Read more
Not usually: Only if accompanied by symptoms like enervation, dizziness, shortness of breath. If naturally occurring (no heart rhythm disturbance or medication adverse effect) and no symptoms, probably would simply observe. Otherwise, underlying conditions need to be sought and treated accordingly. Some may require a pacemaker if symptomatic and not responsive to conservative therapy. ...Read more
Depends: Children and especially infants tend to have a faster heart rate than adults. The importance of bradycardia depends on how slow the heart rate is and on the cause. The heart rate varies in normal adults or children. So a slow heart rate may have no significance. Then again, a very slow heart rate may be a sign that something is wrong especially if associated with symptoms. ...Read more
Bradycardia: This is simply a slow heart rate. In an athlete it can be normal, in a sick individual it can mean there are severe underlying issues. The bradycardia is usually a symptom of something else. If it is primary, coming from a heart that is beating to slowly for no outside reason then it could cause dizziness, lightheadedness, fatigue or tiredness. If you have bradycardia you might need an eval. ...Read more
Nothing or a lot: Not all bradycardia is bad. Some people have resting heart rates that are low without any symptoms. But if its low, the rhythm has bad features, and or the patient is symptomatic, many things need to be considered. What medicines the patient is on, any underlying heart disease, maybe a pacemaker. There are many things to consider for a proper treatment plan. ...Read more
Angina pectoris: Most coronary blood flow occurs during diastole (when the heart is at rest). For patients with blocked arteries and chest pain, slowing the heart rate prolongs diastole allowing more time for blood to get to the heart. Beta blockers are used to slow the heart rate and are effective in controlling chest pain. ...Read more
A pacemaker: If people have symptomatic bradycardia ie dizzy light headedness etc. The may need a pacemaker. If pts heart rates are low around 30 beats per minute or have 3sec pauses or longer and aren't on any thing like beta blockers etc a pacemaker will help keep the heart rate at a programmed rate to prevent symptoms. ...Read more
Medication: A slow heart rate can be normal in fit individuals at rest. Many medications, notably beta blockers, slow the heart rate. A slow heart rate can also be due to disease of the av node, which conducts impulses from the atria to the ventricles. This can be due to scarring from heart attack or aging, and is seen in some infections such as lyme disease and chagas disease. ...Read more
Old people: The conducting system (like electricle wiring) of the heart tends to wear out as you get older so that it is the older patients who most commonly have bradycardia severe enough to cause problems. Slow pulse can be seen in younger patients such as from lyme disease. Less commonly, heart attacks can be the cause. Healthy athletes can get a slow pulse but they are fine, no suffering. ...Read more
