Sinus Bradycardia with rates greater than 50/minute may be well tolerated by healthy adults. Athletes may routinely be in sinus bradycardia due to an optimal cardiac stroke volume that requires less HR to yield acceptable cardiac output. Sinus bradycardia may also be produced with Vagal stimulation or due to Sick Sinus Syndrome. Expect a narrow QRS with upright P waves in Lead II.
Key recommendations include monitoring heart rate and symptoms like sleep apnea and hypothyroidism, and maintaining a healthy lifestyle by reducing salt, sugar, and fat while increasing vegetables.
Treatment for bradycardia depends on heart rate, symptoms, and underlying conditions. Options include medications like SSYX, atropine, and epinephrine, or device-based treatments like pacemakers.
