The Cardiac Conduction System
The pacemaker of the heart
What is the SA node?
A condition where the heart suddenly stops beating
What is sudden cardiac arrest?
A device records the heart’s electrical activity
What is ECG or EKG?
the first aid treatment for cardiac arrest
What is CPR?
This node delays the signal to allow the ventricles to fill
What is the AV node?
A slow heart rate caused by SA node dysfunction
What is Sinus bradycardia?
Can detect arrhythmias during normal daily activity
What is holter monitor?
A device that corrects slow heart rhythms
What is a Pacemaker?
sends impulses through the septum to the ventricles
What is the Bundle of His?
A delay or complete block in electrical signal from atria to ventricles
What is AV block?
ECG wave that represents atrial depolarization
What is P wave?
Medication that can control abnormal rhythms
What are Antiarrhythmic drugs?
Fibers that distribute the impulse to the ventricular walls
What are the Purkinje fibers?
A rapid, irregular heart rhythm originating in the atria
What is Atrial fibrillation?
A monitored exercise test to assess heart function
What is a stress test?
Surgery that reroutes blood around blocked arteries
What is Bypass surgery?
Pumps blood out of the heart
What are ventricles?
A condition characterized by rapid, uncoordinated ventricular contractions
What is ventricular fibrillation?
Uses sound waves to create moving images of the heart
What is Echocardiogram?
Delivers shocks to correct dangerous arrhythmias
What is an ICD?
