What rhythm do the P waves represent?

The P waves represent the electrical activity that causes the atria to contract in the heart. They occur before the QRS complex on an electrocardiogram (EKG) and signify the depolarization of the atria.


The p wave of the electrocardiogram is a signal from?

The P wave on ECG corresponds to electrical depolarization of the atria. It should be positive in lead II and negative in aVR when the P wave originates in the sinoatrial node.


What causes airbag deployment?

an electrical signal up to the airbag and it deploys


What is the correct sequence of events in a heart beat?

The correct sequence of events in a heart beat begins with the heart's sinoatrial (SA) node generating an electrical signal that causes the atria to contract, pumping blood into the ventricles. The electrical signal then travels to the atrioventricular (AV) node, which delays the signal slightly before passing it to the ventricles, causing them to contract and pump blood out of the heart. Finally, the heart relaxes before the next cycle begins.


What two chambers are stimulated immediately after the SA node depolarizes?

The two chambers that are stimulated immediately after the SA node depolarizes are the atria. The electrical signal spreads from the SA node to the atria, causing them to contract and pump blood into the ventricles.


Does the AV node initiates the contraction of the atria?

No, the sinoatrial (SA) node initiates contraction of the atria, which subsequently causes stimulation of the AV node, which then initiates contraction of the ventricles via the Purkinje fibers.


What node triggers an im pulse that causes both atria to?

the atriventriculart node causes both atria to contract


When is an impulse an electrical signal?

When a stimulus causes positively charged ions to diffuse into the neuron.


Where is the electrical conduction of the atria located?

Purkinje fibers


What two components of the conduction system constitute the only electrical link between the atria and the ventricles?

The atrioventricular node and the bundle of HIS are the electrical conduction link between the atria and the ventricles.


What Node that triggers an impulse that causes both atria?

The Sinoatrial Node sends a wave of electric impulses through the heart, which causes both atria to contract.
