Overview
Sinus bradycardia does not necessarily refer to the presence of an obvious pathology; in fact, it may occur in normal, healthy individuals including well-trained athletes, some elderly people or during sleep. It may also be due to an exaggerated response to normal physiological processes (e.g. vomiting, coughing, defecation) or from pathologies involving the SA node such as sick sinus syndrome, myocardial infarction. The most common medications causing sinus bradycardia are beta blockers, digitalis and calcium channel blockers. However, life-threatening conditions including chemical poisoning (organophosphate, sarin), sepsis, electrolyte imbalance should be promptly recognized and treated.
Causes
Life Threatening Causes
Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated.
- Beta blocker overdose
- Carbamate poisoning
- Cervical spine injury
- Digitalis toxicity
- Drowning
- Electric shock
- Electrolyte imbalance
- Hypoglycemia
- Increased intracranial pressure
- Lily of the valley poisoning
- Lithium toxicity
- Myocardial infarction
- Nerve agent poisoning e.g. sarin
- Organophosphate poisoning
- Rabies
- Sepsis
Common Causes
- Aging
- Beta blocker
- Calcium channel blocker
- Cardiac catheterization
- Electrolyte imbalance
- Hypothermia
- Hypothyroidism
- Myocardial infarction
- Nausea
- Obstructive sleep apnea
- Sedative
- Sepsis
- Sleep
- Sick sinus syndrome
