Often sinus node dysfunction produces no symptoms, especially early in the disease course. Signs and symptoms usually appear in more advanced disease and more than 50% of patients will present with syncope or transient near-fainting spells as well as bradycardias that are accompanied by rapid heart rhythms, referred to as tachycardia-bradycardia syndrome [4] [5] Other presenting signs or ...
In clinical practice, elderly people over age 65 and young athletes of both sexes may have sinus bradycardia. [1] The US Centers for Disease Control and Prevention reported in 2011 that 15.2% of adult males and 6.9% of adult females had clinically defined bradycardia (a resting pulse rate below 60 BPM). [41]
Rhythm strip of sinus bradycardia at 50 bpm. Sinus bradycardia is commonly seen in normal healthy persons and athletes in the absence of pathophysiological diseases or conditions. [1] Different factors or etiologies could lead to the dysfunction of the sinus node, causing a malformation or prolongation of the impulse.

[1] It can occur after damage to the central nervous system, such as spinal cord injury and traumatic brain injury.
[citation needed] Most stable patients have persistent bradycardia-related symptoms and require identification and treatment of any reversible cause or permanent implantable pacemaker. Reversible causes of complete AV block should be ruled out before the insertion of a permanent pacemaker, such as drugs that slow heart rate and which induce ...
Traffic deaths continue to be one of the highest causes of death for many age groups. According to the Tennessee Department of Transportation, nearly 40,000 people are killed annually in traffic ...
Those patients whose heart rate was above 70 beats per minute had significantly higher incidence of heart attacks, hospital admissions and the need for surgery. Higher heart rate is thought to be correlated with an increase in heart attack and about a 46 percent increase in hospitalizations for non-fatal or fatal heart attack. [73]
