Right atrium
Receives blood from veins; pumps to right ventricle
Right ventricle
Pumps blood to lungs
Left Atrium
Receives blood from lungs; pumps to left ventricle

Pumps blood through the aorta to the body
Tricuspid
Mitral (Bicuspid)
Pulmonary Valve
Aortic Valve
Circulation of blood in the heart
What is the only ARTERY that carries deoxygenated blood
Pulmonary arteries
What is the only VEIN that brings oxygenated blood to the lungs
Pulmonary veins
Cardiac conduction system
A system of specialized muscle tissue that conducts electrical impulses that stimulate the heart to beat; automatic/involuntary; regulated by cardiac control centers in the brain
Pulse

Help with clotting
Acute Coronary Syndrome (ACS)
- AKA cardiac compromise
- Blanket term for any time the heart may not be getting enough oxygen
- Symptoms often mimic non-cardiac conditions
- Treat all patients with ACS-like signs and symptoms as though they are having a heart problem
Common ACS symptoms
- Chest pain is best-known symptom
- The chest pain can be described as crushing, dull, heavy, and squeezing or will be described as only pressure or discomfort; radiates to arms, upper abdomen, and jaw
- Shortness of breath
Associated signs and symptoms of ACS
- Anxiety and feeling of impending doom
- Nausea and pain/discomfort in upper abdomen
- Sweating
- Abnormal pulse
- Abnormal blood pressure
What are the three patient populations that have atypical presentation in ACS
- Women
- Diabetics
- Elderly
Secondary assessment AFTER doing normal primary assessment for cardiac
- Use OPQRST-ASPN to get HPI
- Obtain SAMPLE history
- Take baseline vitals
- ASPN
Focused physical assessment for cardiac
- Look for perfusion (pulse in all extremities, capillary refill) in all extremities
- Lung sounds
- Inspection of chest
- Palpation of chest (rule our pleuritic chest pain)
- JVD
12 Lead EKG
- If trained and authorized to do so, obtain a 12-lead EKG for chest pain
- An EKG is a paper print out that reflects the electrical activity of the heart
- 12-lead tells us about STEMI
What does STEMI (12-lead) stand for
- ST: Segment
- E: Elevation
- M: Myocardial
- I: Infarction
Treatment for true chest pain
- Position of comfort
- O2 if appropriate
- Aspirin
- Nitroglycerin
- Transport to a cardiac center (emergency cath lab)
Coronary Artery Disease
- Underlying condition for MI
- Conditions that narrow or block arteries of heart
- Often result from fatty deposit build-up on inner walls of arteries
- Build-up narrows inner vessel diameter, restricts flow of blood
Types of coronary artery disease
- Thrombus: Blood clot on the inner surface of an artery
- Embolus: Piece of blood clot breaks loose and flows to a smaller artery
- Occlusion: Blockage of a blood vessel; reduced blood supply to myocardium causes emergency in majority of cardiac-related medical emergencies
Aneurysm
Weakened sections of blood vessels begin to dilate (balloon); bursting (rupture) can cause rapid, life-threatening internal bleeding
Electrical Malfunction of the Heart
- Malfunction of heart’s electrical system generally results in dysrhythmia (abnormal rhythm)
- Dysrhythmias include bradycardia, tachycardia, and rhythms that may present when there is no pulse
Mechanical malfunctions of the heart
- Angina pectoris
- Acute MI (AMI)
- Congestive Heart Failure (CHF)
Angina Pectoris
- Type of mechanical malfunction of the heart
- Chest pain caused by insufficient blood flow to the myocardium
- Typically due to narrowed arteries secondary to coronary artery disease
- Pain usually during times of increased myocardial oxygen demand, such as exertion or stress
AMI
- Type of mechanical malfunction of the heart
- Death of a portion of the myocardium due to lack of oxygen
- Coronary artery disease is usually the underlying reason
- Signs and symptoms: Typical ACS
CHF
- Type of mechanical malfunction of the heart
- Inadequate pumping of the heart
- Often leads to excessive fluid build-up in lungs and/or body
- May be brought on by diseased heart valves, hypertension, obstructive pulmonary disease
- Often a complication of AMI
Progression of CHF
- Patient sustains AMI
- Myocardium of left ventricle dies
- Because of damage to left ventricle, blood backs up into pulmonary circulation and lungs
- If untreated, left heart failure commonly causes right heart failure
Signs/symptoms of CHF
Signs:
- Tachycardia
- Dyspnea and cyanosis
- Normal/elevated blood pressure

What must happen for heart to function
Function of heart if to pump blood:
- Electrical function and mechanical functions must work together
- Electrical stimulation causes muscles to contract
- Pumping muscle requires oxygenated blood
- Without oxygenated blood, pumping fails
Mechanical Failure of the heart
- Loss of normal heart muscle structure
- MI
- Chronic hypertension
- Loss of normal heart valve function
- Direct trauma
- Pulseless electrical activity (PEA) indicates mechanical failure
Asystole
No electrical functional of the heart (flat line); not shockable
Ventricular Tachycardia
Too often; shockable because there is still activity
Ventricular Fibrillation
No pattern; shockable bc there is still activity
Electrical dysfunction of the heart
Sudden cardiac arrest
- Abrupt onset of dysrhythmia
- Acute blunt trauma to the chest causes commotio cordis (has to be very specific; low chance; Damar Hamlin)
- Oxygen levels are relatively normal at beginning
Asphyxial cardiac arrest
- Heart stops pumping due to systemic hypoxia
- Result of low oxygen levels in blood
- Appears with more warning than sudden cardiac arrest
- Quality ventilations are important during CPR; no point in respirations without oxygen
Agonal Respirations
- Occurs breathing occurs as a primal reflex during cardiac arrest
- Small amount of oxygen allows medulla to send impulses to respiratory muscles
- A downward spiral will end in death unless someone intervenes
Effects of cardiac arrest
- Heart fails to pump
- Blood stops moving
- Cells are robbed of essential oxygen and nutrients
- Organs are damaged and eventually fail
- Patient will die if uncorrected
- Goal is to intervene as early as possible
Pediatric cardiac arrest
- Cardiac arrests in children are generally asphyxia in nature
- Caused by choking, shock, or resp problem
- Cardiac arrest in children is usually a predictable outcome after steady and rapid decompensation
Three commonly reported types of Sudden Unexpected Infant Death Syndrome (SUIDS)
Three commonly reported types of SUID:
- Sudden infant death syndrome (SIDS)
