Sinus bradycardia is a heart rhythm that’s slower than expected, but otherwise normal. Severe cases that cause symptoms are treatable with medication or a pacemaker.
Treating underlying conditions: If something like thyroid disease, sleep apnea, or an infection is causing sinus bradycardia, a doctor can help develop a treatment plan to address it.
Treatment. Treatment for bradycardia depends on the severity of symptoms and the cause of the slow heart rate. If you don't have symptoms, treatment might not be necessary. Bradycardia treatment may include lifestyle changes, medication changes or an implanted device called a pacemaker.
Sinus bradycardia means that your heart is beating regularly, but slower than normal. Sinus bradycardia is usually a benign arrhythmia (especially in very active people). That means while it's slower than expected, it also isn't harmful.
Sinus arrhythmia, the fluctuation in sinus rate with respiratory cycles, often accompanies sinus bradycardia. (See "Normal sinus rhythm and sinus arrhythmia".) The etiology, clinical presentation, evaluation, and management of sinus bradycardia will be reviewed here.
How Is Sinus Bradycardia Treated? The treatment of slow heart rate depends on whether the cause is sinus bradycardia or heart block and whether it's reversible or not. Treatment may include lifestyle changes, medication changes, or an implanted device called a pacemaker.
Treatment of bradycardia. Borderline or occasional bradycardia may not require treatment. Severe or prolonged bradycardia can be treated in a few ways. For instance, if medication side effects are causing the slow heart rate, then the medication regimen can be adjusted or discontinued.
Sinus bradycardia is a cardiac rhythm with appropriate cardiac muscular depolarization initiating from the sinus node and a rate of fewer than 60 beats per minute (bpm). The diagnosis of this condition requires an ECG showing a normal sinus rhythm at a rate lower than 60 bpm.
You probably don't need treatment unless you have symptoms. Sinus bradycardia is unlikely to cause you complications unless your heart rate goes below 40 beats per minute. If your heart rate...
Summary. Sinus bradycardia is any heart rhythm slower than 50 bpm, even if transient, owing to sinus node dysfunction and/or atrioventricular (AV) conduction abnormalities. Causes include intrinsic sinus node, AV nodal, and His-Purkinje disease, or extrinsic influences, which may be reversible.
