This is part of: Sinus node rhythms and arrhythmias
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 sinus bradycardia the sinus node fires at a slow (<60 bpm) rate. Causes of sinus bradycardia include:

  • Normal physiology in an athelete
  • Medication (beta-blockers)
  • Ischemia (typically inferior myocardial infarction with involvement of the sinus node artery)
  • Hypothermia
  • Hypothyroidism.
  • Neuro-mediated bradycardia, such as in a vasovagal reaction
