An enlarged heart.
The ____ fills coronary arteries
____ ____ is the amount of blood ejected from the left ventricle w/each contraction.
The end of diastolic volume.
Increased stretch on ventricular muscle, causes increased contraction which increases the stroke volume.
____ is the resistance to left ventricular ejection.
____ _____ can be caused by blood vessels, hypertension, atherosclerosis, and hypervolemia.
____ nervous system influences the rate of impulse generation and speed of conduction pathways.
____ nervous system increases the rate of impulse transmission and innervates all parts of atria and ventricle
The cardiac ____ system generates the electrical impulses that control the rhythmic relaxation and contraction of the atria and ventricles.
The ____ system decreases the rate and innevates atria, ventricles, sinoatrial and atrioventricular nodes.
The ____ system originates with the SA node or pacemaker, transmitted to the AV node, bundle of his and purkinje fibers.
____ node begins conduction.
The ___ ___ represents electrical conduction through both atria.
The ___ ____ is the duration of electrical impulses as they travel through the ventricles; ventricular contraction.
The ____ ____ describes ventricular depolarization and repolarization.
The active process stimulated by chemical receptors in the aorta.
The passive process from elastic recoil.
Moves blood to and from the alveolar capillary membranes for gas exchange.
Gas exchange of O2 & CO2:
O2 - lungs to blood CO2 - blood to alveoli and exhaled
Amount of Air exhaled in normal breath.
The amount of blood ejected from teh left ventricle each minute.
The amount of blood ejected from the left ventricle with each contraction.
Cardiac output divided by Body surface area; normal range is 2.5 to 4.0 L/min.
Reflects the electrical activity of the conduction system; monitors the regularity and path of electrical impulses.
Represents the electrical conduction through both atria: Atrial conduction follows the P wave.
Represents the travel time of the electrical impulse from SA node to Purkinje fibers.
Represents teh electrical impulse traveled through the ventricles.
Represents the time needed for ventricular depolarization and repolarization.
The process of moving gases into and out of the lungs.
The major inspiratory muscle of respiration.
The ability of the cardiovascular system to pump oxygenated blood to the tissues and return deoxygenated blodd to the lungs.
Exchange of respiratory gases in the alveoli and the capillaries of body tissues.
Chronic obstructive pulmonary disease:
Measures the volume of air entering or leaving the lungs.
Anemia and CO2 poisoning:
Are examples of physiological factors that decreased oxygen-carrying capacity of blood.
High altitudes and drug overdoses:
Are examples of decreased inspired oxygen concentration.
Reduced circulating blood volume.
Shock & severe dehydration:
Two causes of extracellular fluid loss and reduced circulating blood volume.
Fever, pregnancy, wound healing & exercies:
Are examples of increased metabolic activity that increases oxygen demand.
Disturbances in conduction caused by electrical impulses that do not originate from the SA node.
Abnormal narrowing of heart valves.
Causes the backflow of blood into adjacent chamber.
Myocardium does not receive sufficent blood flow from coronary arteries.
Normal sinus rhythm:
There is a P wave for every QRS.
0.12 - 0.20 and constant
Fibrillation is an uncontrolled twitching or quivering of muscle fibers and occurs in the lower chambers of the heart. During ventricular fibrillation, blood is not removed from the heart. Sudden cardiac death results.
A pulse rate of more than 100 beats per minute, with at least three irregular heartbeats in a row; can develop as an early or late complication of a heart attack.
An indicator of heart failure when in the thousands.
60% or more:
The amount of blood ejected from a healthy heart.
40% or less:
The amount of blood ejected from heart in failure.
Looks for thickening of muscles in response to exercises; no thickening indicates a potential problem.
Inadequate tissue oxygenation at the cellular level.
Alveolar ventilation is inadequate to meet O2 demands or eliminate sufficient C02.
A collapse of the alveoli, preventing normal gas exchange.
Visualizes cardiac chambers, valves, the great vessels and coronary arteries. Measures presures and volumes within four chambers.
ECG Exercise stress test:
Evaluates cardiac response to physical stress.
