Heart functionality
The passive stretching of the muscle fibers in the ventricles during diastole
What is Preload
transmission of electrical impulses depend on
what is automaticity, excitability, conductivity, and contractility of cardiac cells.
First nursing intervention for this arrhythmia is to have the patient "bear down"
What is SVT
Sound caused by valves closing in the heart
What is Lub Dub or S1 S2
Normal PR and ORS interval measurements
What is .12-.20 and .06-.12
The pressure that the ventricular muscles must generate to overcome the higher pressures in the aorta to get the blood out of the heart.
What is Afterload
The Impulse Trail
What is Sinoatrial Node to Atrioventricular Node to Bundle Of His to Bundle Branches and lastly to Purkinje Fibers
This medication slows and strengthens the heart and has a narrow therapeutic blood level
What is digoxin?
Largest muscle in the heart d/t the strength needed to overcome vascular resistance
What is the Myocardium of the left ventricle
Itty bitty box and normal box measurements
What is 0.04 and .20
This is responsible for 30% of the cardiac output – the amount of blood pumped by the ventricles in 1 minute.
What is Atrial contraction or atrial kick
Natural pacemaker of the heart
what is SA node
Atropine and pacer pads should be ready for this arrhythmia
What is symptomatic bradycardia
This coronary artery is the largest of your hearts arteries and feeds mostly the left side of the heart and is known as the windowmaker if complete blockage is present
What is the Left Anterior Descending (LAD) artery
What is Normal Sinus Rhythm?
The amount of blood pumped out of a ventricle during one contraction
What is Stroke Volume
Gatekeeper of the heart
What is the AV node? It's job is to delay the impulses traveling through the heart
Electrical interference, dry electrodes, and poor conduction can all cause this
What is Artifact
These are the four main coronary arteries
Right coronary artery, Left coronary artery, Left anterior descending (LAD) artery, and Left circumflex artery.
A coordinated rapid beating of the atria, the second most common tachyarrhythmia.
What is Atrial Flutter?
The amount of blood pumped out of the heart to the body per minute. 4-8L/min
What is Cardiac output
When this pacemaker takes over in the heart, the heart fires at a rate of 20-40 BPM
What is Purkinje Fibers
Assessing the patient, giving oxygen, monitoring VS, checking IV patency/starting IV, and notifying MD
What is Nursing interventions of cardiac arrythmias
Pathway of blood flow through the heart
What is Inferior or superior vena cava to the right atrium, through tricuspid valve, to right ventricle, through pulmonary semilunar valve, to pulmonary arteries, to lungs to get oxygenated, then back to pulmonary veins, to the left atrium, through the bicuspid valve to the left ventricle, through the aortic semilunar valve, to the aorta and systemic circulation!
Encompasses all tachy dysrhythmias in which heart rate is greater than 150 bpm
What is Supraventricular Tachycardia?
