Slow Heart Rate (Definition)

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

How dangerous is sinus bradycardia?

How dangerous is sinus bradycardia?

Depends: Heart rates above 50 are usually well-tolerated. Once below 50 symptoms usually develop. Heart rates approaching 30s can be dangerous. Overall any slow heart rate that is associated with symptoms can be dangerous. Read more

Is bradycardia dangerous even it's not an AV block? Or life threatening? And can this suddenly progress to getting worse? (sick sinus syndrome?)

Is bradycardia dangerous even it's not an AV block? Or life threatening? And can this suddenly progress to getting worse? (sick sinus syndrome?)

Fainting: Even by itself, the slowed heart rate could lead you to pass out, which is certainly dangerous if you're driving for example. That being said, as you suggested, bradycardia could be indicative of a greater underlying process which would require elucidation. Read more

Does bradycardia progress?

Sometimes: It depends on the situation. In young people, it is quite common to have a low heart rate (to a point), mostly due to high vagal tone or a strong parasympathetic nervous system. Most concerning would be if it was associated with dizziness or episodes of passing out. Read more

Why does bradycardia happen?

Why does bradycardia happen?

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

What are causes of bradycardia?

What are causes of bradycardia?

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

What does marked bradycardia mean?

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

Is bradycardia harmful on the body?

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

What does bradycardia do in a child?

What does bradycardia do in a child?

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

What are the effects of bradycardia?

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
