Sinus dysrhythmia is characterized by an irregularity in the rhythm during inspiration and expiration. This is due to changes in intrathoracic pressure during breathing. Sinus tachycardia and sinus bradycardia refer to the rate of the heart rhythm, while normal sinus rhythm refers to a regular rhythm with a rate between 60-100 beats per minute.
