What is the treatment for sinus bradycardia?
Bradycardia treatment may include lifestyle changes, medication changes or an implanted device called a pacemaker. If an underlying health problem, such as thyroid disease or sleep apnea, is causing the slower than normal heartbeat, treatment of that condition might correct bradycardia.
What causes sinus bradycardia ECG?
The causes of sinus bradycardia include the following: AV blocking medications (beta-blockers, nondihydropyridine calcium channel blockers, digoxin) Heightened vagal tone (i.e. well-trained athlete) Sick sinus syndrome.
What is the most common cause of sinus bradycardia?
One of the most common pathologic causes of symptomatic sinus bradycardia is the sick sinus syndrome. The most common medications responsible include therapeutic and supratherapeutic doses of digitalis glycosides, beta-blockers, and calcium channel-blocking agents.
When do you treat asymptomatic bradycardia?
Asymptomatic bradycardia: Usually, no treatment is required. If second-degree AV block, Mobitz II, or third-degree AV block is present: Consider transcutaneous pacing or transvenous pacing.
Can you live a normal life with bradycardia?
If you have bradycardia, your resting heart rate is slower than usual—beating fewer than 50 times per minute. Bradycardia can be harmless, but in some cases it can be life-threatening.
Is it OK to exercise with bradycardia?
If you do not have other heart problems, you likely do not have limits on the type or level of activity that you can do. You may want to walk, swim, bike, or do other activities. Ask your doctor what level of exercise is safe for you. Stay at a healthy weight.
Is coffee good for bradycardia?
Caffeine reduced the heart rate and survival considerably at 1000 mg/L, supporting the notion of caffeine-induced cardiac arrest resulting from bradycardia.
Is sinus bradycardia on ECG normal?
In sinus bradycardia, the heartbeat is starting in the normal part of the electrical system, the SA node, but the beat is slow. Many adults and children have sinus bradycardia that does not cause symptoms. In these cases, the bradycardia is a normal event and does not mean there is a heart problem.
When does sinus bradycardia require treatment?
A patient with sinus bradycardia should be evaluated for hemodynamic instability. If found to be hemodynamically unstable, the patient can be treated with intravenous (IV) atropine 0.5 mg push every 3 to 5 minutes up to 3 mg total.
When should I worry about bradycardia?
Bradycardia can be a serious problem if the heart rate is very slow and the heart can’t pump enough oxygen-rich blood to the body. If this happens, you may feel dizzy, very tired or weak, and short of breath. Sometimes bradycardia doesn’t cause symptoms or complications.
What drugs cause sinus bradycardia?
A broad variety of other drugs and toxins have been reported to cause bradycardia, including lithium, paclitaxel, toluene, dimethyl sulfoxide (DMSO), topical ophthalmic acetylcholine, fentanyl, alfentanil, sufentanil, reserpine, and clonidine. Sinus bradycardia may be seen in hypothermia, hypoglycemia, and sleep apnea.
How dangerous is sinus bradycardia?
Types of bradycardia. In many cases, bradycardia is not a dangerous condition and does not require treatment. For example, sinus bradycardia is a type of bradycardia that occurs in response to being deeply relaxed or extremely fit.
What is the prognosis of sinus bradycardia?
Prognosis is good when the rhythm is promptly identified by a healthcare provider. However, patients with sick sinus syndrome who have bradycardia tend to have a poor prognosis with 5-year survival rates between 45-70\%.
What conditions can cause sinus bradycardia?
Causes of pathophysiologic sinus bradycardia include: Advanced age Problems with the SA node (sick sinus syndrome) Inflammatory heart conditions, like pericarditis or myocarditis Heart conditions that exist at birth (congenital) Increased pressure inside the head (for example, in an injury to the brain) Heart attack (myocardial infarction) Obstructive sleep apnea
