In sinusbradycardia the sinus node fires at a slow (<60 bpm) rate. This can be caused by e.g.: medication (beta-blockers), ischemia (typically inferior myocardial infarction with involvement of the sinus node artery), hypothermia and hypothyroidism. In an athlete a resting heart rate of < 60 bpm often is normal.
