===Sinus Bradycardia===
Sinus bradycardia is a slow sinus rhythm of <60 beats per minute. Sinus bradycardia can be physiological, as is athletes or during sleep. Commonly sinus bradycardia is caused by medication, ischemia or neuro-mediated bradycardia, such as in a vasovagal reaction. Furthermore metabolic diseases can cause bradycardia, e.g. hypothermia or hypothyroidism.

Line 49: Line 51:
If the sinus node has a problem with impulse formation it is defined as a sinus arrest. There can be the appearance of a irregular rhythm, however sinus P-waves are clearly present. In comparison with the sinus node exit block, there is no relation with a previous P-P interval. Often an ectopic pacemaker takes over lower in the conduction system, but the new rate varies slightly from the old one.
