Common cardiac Problems:

Cardiac Compromise-Chest pain or discomfort that is related to the heart usually comes from
ischemia- lack of oxygen due to partial or complete blockage of the artery
Ischemic heart disease- disease involving insufficient blood flow to one or multiple parts of the
heart
Arteriosclerosis- build up of calcium and fatty tissue (plaque) inside the walls of the artery: this
buildup can eventually cause an occlusion- blockage of blood flow
Lumen- inside diameter of the artery
Acute Myocardial Infarction (AMI)- a heart attack: dead cardiac tissue as a result of an ischemic
episode in which blood flow was not restored in time for tissue to repair itself
Cardiac arrest- the hearts inability to pump
Angina pectoris- pain that is caused when the heart muscle does not get enough blood for a
brief period of time, this can also be caused by a spasm of the artery

Chest pain/discomfort/pressure
Pain or discomfort in the jaw/arms/back/abdomen/neck
Sudden arrhythmia (abnormal heart beat)
Syncope- fainting
Shortness of breath or dyspnia
Pulmonary edema
Sudden death
The pain of a heart attack: page 409
1. May or may not be caused by exertion
2. Does not resolve in a few minutes (last for 30 minutes to several hours)
3. May or may not be relieved by rest or nitro
Physical findings of a heart attack (page 409):
1. Pulse
a. Increase rate
b. Irregular rhythm
2. Blood pressure may or may not be effected by heart attack
3. Respiration
a. Usually normal
b. CHF may cause them to become rapid and labored
4. General appearance
a. Frightened
b. Nausea/vomiting
c. Cold sweat/ clammy
d. Gray/ashing or bluish skin
5. Mental status
a. Overwhelming feeling of impending doom
Heart rhythms and rates: page 410

Tachycardia-

Bradycardia-

Ventricular tachycardia (VT) – sometimes referred to as SVT (super ventricular tachycardia)-

Ventricular fibrillation (V-Fib)-

Asystole-

Cardiogenic shock (page 410-411)
CHF(Page 412):
Congestive heart failure- when the heart muscle can no longer keep up with the return flow of blood
Dependent edema- collection of waist fluid in the body (usually in the feet, legs, or chest)
