- Sinus arrest occurs when the sinoartial node fails to discharge resulting in a pause of the normal heart rhythm.
- Sinus block occurs when the sinoatrial node fails to conduct the wave of depolarisation resulting in a pause of the normal heart rhythm.
- The presence of a sinus arrest on an ECG would be characterised by an absence of P-QRS-T complexes for more than two R-R intervals.
- The presence of a sinus block on an ECG would be characterised by an absence of P-QRS-T complexes for twice the R-R interval.
Treatment:
- Treat the underlying condition
- Drugs used in the treatment of sinus arrest and sinus blocks are the following: glycopyrrolate, isoprenaline, atropine
