Cardiovascular Emergencies Flashcards
Where does de-oxygenated blood enter the heart from?
Superior and Inferior Vena Cava
What part of the heart acts as the pace maker and is located at the upper right atrium?
Sinoatrial Node (SA)
What part of the heart acts as a delay gate for the electrical pulse generated by the sinoatrial node and is located between the atria and ventricles?
Atrioventricular Node (AV)
What part of the heart causes its contraction and sends blood out to lungs?
His-Purkinje Network
What wave reads the polarization in the atria as it contracts?
P-Wave
Which wave reads the polarization of ventricles as blood squeezes into the heart?
QR- Wave
Which wave reads the electrical status of the heart after the atrioventricular node closes and ventricles are still depolarizing?
RS - Wave
Which wave reads the electrical pulse of the heart when atria is beginning to fill up as pressure increases in ventricle?
ST Wave
Wave that reads the re polarization of the ventricles?
T-Wave
Quivering Heart Rhythm?
Ventricular Fibrillation
Heart rate exceeds 100 BPM at rest?
Ventricular Tachycardia
Abnormal Heart Rhythm
Dysrhythmia
Absence of Heart Rate
Asystole
4 Chains of Rescue
- Call for help
- Early CPR
- Early Defibrillation
- Recovery

Areas of pain
Neck Jaw Back Chest Shoulder Anterior Chest
During which wave of an electrocardiogram does the atria contract, forcing blood into the the ventricles (also depolarization of the atria)?
P-Wave
Which structure of the heart is considered the “pacemaker” and is located in the right upper atrium?
SA node
What is the cardiac condition in which the heart loses its ability to pump efficiently and often occurs following a heart attack?
Congestive Heart Failure
True or False: Cardiac output is the amount of blood that is pumped through the body per minute.
True
