Sinusbradycardia
{{{locatieafbeelding}}}
Atrial rate < 60 bpm
Ventricular rate same
Regularity regular
Origin sinus node
P-wave normal
Effect of adenosine slows down
Example ECG: Sinusbradycardia of around 40 bpm.Sinusbradycardia
Example ECG2:

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.
