Sinus Bradycardia

Sinus bradycardia is a type of slow heart rate that originates in the sinus node. It is characterized by a heart rate of fewer than 60 beats per minute in adults, which is slower than the normal resting heart rate of 60-100 bpm. This condition can be normal for some individuals, especially athletes or those who are very fit, but in other cases, it may be a sign of an underlying health
