Sinus bradycardia is a condition where the heart beats slower than usual. This article breaks down the causes, symptoms, and treatments associated with this intriguing heart rhythm.
What is Sinus Bradycardia?
Sinus bradycardia occurs when the heart rate drops below 60 beats per minute. This slower rhythm originates from the heart's natural pacemaker, the sinoatrial node. While often harmless, it can sometimes signal underlying health issues.
