Question: is sinus bradycardia an arrhythmia?
Answer: Sometimes, sinus arrhythmia occurs with another condition called sinus bradycardia. Bradycardia, or a slow heartbeat, is diagnosed when your heart's natural rhythm is below 60 beats per minute. If the low heart rate produces lengthy pauses between beats, you may have sinus bradycardia with sinus arrhythmia.
