This is termed the pacemaker of the heart and generates the initials phase of a heart beat
What is the SA Node
The blood returning to the heart enters this area 1st.
What is the Right Atrium
This is absence of a heart rhythm-complete standstill.
What is Asystole
Discharge of an electrical charge
What is depolarization
This represents atria depolarization.
What is the P wave
This area can stimulate a heartbeat of 40-60 if the SA node does not.
What is the AV node
On 5-lead tele, the LA lead is placed 3-5 inches away from this?
What is a pacemaker
There is a rhythm on the ECG but no pulse.
What is pulseless electrical activity.
The recharging of action potential in the heart
What is Repolarization
This represents Ventricle depolarization.
What is the QRS
This is the hearts natural back up plan to beat if the SA & AV node fail.
In doing a 12-lead ECG the V1 lead is placed here.
What is the RIGHT 4th ICS
This rhythm has chaotic & irregular electrical activity where the bottom of the heart quivers with no cardiac output.
What is Ventricle Fibrillation
This is the baseline of the ECG where there is no positive or negative charge deflections
What is the Isoelectric line
Repolarization of the ventricles
What is the T wave
This procedure sends an electrical impulse, timed to the R wave, and is used to reset and synchronize the hearts Rythm.
What is cardioversion?
This is on the 2nd floor in the ICU wing here or at extension 3455
What is the telemetry room
This rhythm begins in the ventricles causing a wide bizarre QRS. If sustained (30 seconds) they will need to be cardioverted or Vfib could happen.
What is Ventricle Tachycardia
Term used to describe a reduction in blood flow to a certain part of the body
What is Ischemia
Depolarization of the Purkinje fibers
What is the S wave
When the electrical impulse does not reach the ventricles at the same time, the QRS is >.12 & looks like bunny ears. What is this called?
What is a bundle branch block
In this heart block the atria & ventricles can't find each other and are not talking to each other.
What is 3rd degree heart block
When the SA or AV node cannot generate activity ectopic fibers in the ventricles start sending electrical impulses but at a rate of less than 50 beats/min. The QRS is wide, no P wave & can lead to cardiac arrest.
What is Idioventricular
Term used when fibers outside the normal electrical pathway generate heart activity.
What is an Ectopic.
At the end of ventricle depolarization, there is a brief pause of rest.
What is the ST segment
