Is sinus arrest or a sinus pauses dangerous during exercise?

In: Cardiovascular Health [Edit categories]

Answer:

Sinus arrest or sinus pauses sometimes happen due to slow electrical conduction within atrial tissue, Such as during sleep when the SA node discharging impulses slowly. It is more common for it to occur when the heart rate is slow however it CAN occur with normal heart rates.

During exercise the heart will be beating faster so if there is a sinus pauses atrial stand-still could occur unless atrial cells become the pacemaker. It is very unlikely but it could be serious if the SA node pacemaker does not take control of the heart quickly.

Its unlikely to occur.- It sometimes happends during MI or heart attack. MI standing for myocardial- infarctions.
