Generality
Sinus bradycardia is the decrease in heart rate below the lower limit of normal, conventionally set at 60 beats per minute.
It is an "arrhythmia - that is, an" alteration of the normal heart rhythm - which does not involve any irregular heartbeat.
Sinus bradycardia can have a physiological significance or a pathological significance.
Sinus bradycardia, on the other hand, is pathological resulting from conditions / situations such as: sinus node syndrome, hypothyroidism, hypothermia, anorexia nervosa, etc.
An electrocardiogram is essential for a correct diagnosis of sinus bradycardia.
Treatment of sinus bradycardia depends on the underlying cause.
