Sinus bradycardia can be the result of many things including good physical fitness, medications, and some forms of heart block. Sinus refers to the sinus node, the heart's natural pacemaker which creates the normal regular heartbeat.
Sinus bradycardia can be defined as a sinus rhythm with a resting heart rate of 60 beats per minute or less. However, few patients actually become symptomatic until their heart rate drops to less than 50 beats per minute. The action potential responsible for this rhythm arises from the sinus node and causes a P wave on the surface ECG that is normal in terms of both amplitude and vector. The presence of sinus bradycardia in itself does not cause a change in the QRS complex and T wave.
