| | Sinus bradycardia occurs when the hearts rate is slower than 60 beats per minute. | | | The pulse volume may be greater due to a greater stroke volume and an increased diastolic run-off time (longer time for blood to flow away from the heart). | | | Increase in parasympathetic (vagal) tone, for instance, due to training in athletes. |
