Anatomy
What are the 4 chambers of the Heart?
Rt. Atrium Rt. Ventricle. Lt. Atrium, Lt. ventricle
Complete absence of all heart electrical activity?
What is Asystole
Angina pectoris occurs
When myocardial oxygen demand exceeds supply.
What is decreased pumping force of the heart muscle
Cardiogenic shock following AMI is caused by:
dilating the coronary arteries and improving cardiac blood flow.
Nitroglycerin
Normal electrical impulse starts?
(SA)node sinoatrial
Slow heart rate less than 60/beats min
What is bradycardia?
Deoxygenated blood from the body returns to the:
right atrium.
Decreased blood flow to one or more portions of the myocardium.
Ischemic heart disease
The electrical stimulus that originates in the heart's primary pacemaker is controlled by impulses from the brain that arrive by way of the
What is autonomic nervous system.
The body's main artery?
Aorta
Rapid heart rate more than 100beats min
What is tachycardia
A patient in cardiac arrest is wearing an external defibrillator vest, which is interfering with effective chest compressions. The EMT should
remove the battery from the monitor and then remove the vest.
External chest pain, relieved by Nitroglycerin
What is Angina pertoris
Sudden death following AMI is MOST often caused by:
What is ventricular fibrillation
Carries blood from the abdomen, kidenys and legs back to the right atrium.
Inferior Vena Cava
wide rapid heart rhythm, impulses begin in Ventricles
What is Ventricle Tachycardia
Cardiogenic shock following AMI is caused by:
what decreased pumping force of the heart muscle.
Often presents with pain that is maximal from the onset.
In contrast to AMI, a dissecting aortic aneurysm:
Ventricular tachycardia causes hypotension because
Name the 4 valves of the Heart
Aortic, Pulmonic, Tricuspid, Mitral
Disorganized, ineffective quivering of the ventricles, no blood flow and a state of cardiac arrest.
What is Ventricle Fibrillation
The right coronary artery supplies blood to the
What is right ventricle and inferior wall of the left ventricle.
Complete blockage of the coronary artery
Acute myocardial infarction
The myocardium receives oxygenated blood from the __________, which originate(s) from the __________.
What is coronary arteries and aorta
