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

What does "clinically significant bradycardia" mean?

What does "clinically significant bradycardia" mean?

See below: "bradycardia" means a heart rate less than 60 beats per minutes. "clinically significant" is an opinion. In my book, it means that the heart rate is causing symptoms. Since the symptoms of slow heart rate can be vague (generally just fatigue or getting out breath earlier than expected), your doctor is offering the opinion that your symptoms may be coming from slow heart rate. ...Read more

Depends on Symptoms: The answer to this depends largely symptoms. In general for a patient with bradycardia, if there is no lightheadedness, dizziness, passing out, or difficulty with exertion there is no major concern. Two caveats: 1) it is important to know the underlying rhythm, something that can easily be checked with an electrocardiogram. 2) the bradycardia could point to another condition like hypothyroidism. ...Read more

I have non-dilated left ventricule with good biventricular systolic function. What does this mean and did I inherit it? I also have bradycardia.

I have non-dilated left ventricule with good biventricular systolic function.  What does this mean and did I inherit it? I also have bradycardia.

Normal: A non-dilated left ventricle would be a normal finding. That biventricular systolic function is good means it's normal as well (normal contractility). More information needed to answer what disease you are asking whether you inherited. ...Read more

Ecg/ekg results: sinus bradycardia with short pr interval, what does this mean?

Ecg/ekg results: sinus bradycardia with short pr interval, what does this mean?

2 things: sinus bradycardia means you have a resting heart rate less than 60, can be normal finding in young, healthy or athletic people, can also be pathologic depending on how low and the clinical scenario. Short PR can mean accelerated AV conduction which is essentially normal, or could me a pre-excitation suggesting presence of a bypass tract (WPW) but usually accompanied with other findings. ...Read more

My mom's ECG reads as Sinus Bradycardia with a single abnormal conducted beat, Left Axis deviation. What does that mean? She is 54 years old.

My mom's ECG reads as Sinus Bradycardia with a single abnormal conducted beat, Left Axis deviation. What does that mean? She is 54 years old.

Rate <60 & Purkinje: fiber damage within endocardium. Any rate below 60 BPM is defined as bradycardia (not unhealthy). The abnormal conduction & LAD both occur as a result of damage to the Purkinje muscle fibers (look this up) within the endocardium of her heart muscle; nearly alway a result of atherosclerosis & heart attacks within the inner wall of the left ventricle-the portion most susceptible to ischemic damage. ...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

Can bradycardia cause syncope?

Can bradycardia cause syncope?

Yes: Syncope is loss of consciousness due to transitory decline in blood flow to brain. This can be caused by irregular heart rate or rhythm or by alteration of blood volume or distribution. ...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

Is bradycardia harmful on the body?

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
