Ventricle

beginning of electrical excitation of the atria and the beginning of excitation of the ventricles and its normal value is 0.12- 0.20 seconds. 2. What does the QRS complex on the ECG represent? What is implicit in the information that the QRS complexes on Mr. Ortega’s ECG had a normal configuration? The QRS complex is the most important in the EKG since its represents depolarization (contraction) of Ventricles. A normal configuration QRS complex means the ventricular contraction is occurring…

mechanical and the neurohumoral issues seen with systolic ventricular dysfunction, one can see how each system and mechanism feeds the other. Hypertension from an unhealthy life style can cause a small amount of damage to the left ventricle. The repair of that ventricle could cause a small amount of ventricular remodeling, which could be just enough to perpetuate a series of events to send the patient into heart…

right atrium, right ventricle, left atrium and left ventricle. The right and left atriums are separated by the interatrial septum and the interventricular septum divides the right and left ventricles. There are atrial-ventricular junctions that differentiate between the atriums and ventricles which contains atrioventricular valves. These valves, known as the tricuspid valve on the right side and mitral valve on the left side, are present to prevent backflow from the ventricles into the atrium.…

is thicker than that of the right side. • Right side circulates the deoxygenated blood while the left side circulates oxygenated blood. • Right atrium receives blood from tissues and organs, and right ventricle pumps it to lungs. However, the left atrium receives blood from lungs and left ventricle pumps it to the rest of the body. • Superior vena cava and inferior vena cava bring blood to right side of the heart but only pulmonary vein brings blood to left…

atria and ventricles. Between the right atrium and right ventricle, the tricuspid valves exist; and the mitral valve separates the left atrium and left ventricle. Chordae Tendineae, which are attached to the AV valves and anchored to the papillary muscles, allow one-way flow by preventing eversion of the valves. Semilunar valves separate the ventricles from the arterial system. The aortic valve separates the left ventricle from the aorta while the pulmonary valve divides the right ventricle and…

Heart failure is a common killer of both men and women in the United States every year. It is a very serious issue that plagues this country and other developed countries like it. Heart failure is a syndrome with many risk factors, such as, age, obesity, congenital heart diseases, and many others. A client is considered to be in heart failure, when their heart is unable to profuse tissues in the body with oxygenated and nutrient rich blood for tissue to sufficiently function. A client when…

the atria, causing muscle contractions that pump blood into the ventricles. The electrical impulses then arrive at a cluster of cells called the atrioventricular (AV) node, usually the only pathway for signals to travel from the atria to the ventricles. The AV node slows the electrical signal before sending it to the ventricles. This slight delay allows the ventricles to fill with blood. When electrical impulses reach the ventricles, muscle contractions pump blood to the lungs and the rest of…

replenished by the food ingested. In the right ventricle, impurities in the blood were expelled into the pulmonary artery and then exhaled from the lungs. While purified blood went to the left ventricle through invisible pores in the interventricular septum and combined with pneuma that came from the pulmonary veins to cool down the body. Subsequently, the mixture of pnuema and the small amount of blood traveled to the pulmonary arteries. The left ventricle…

It can either serve to provide an extra ventricle or act as a substitute for the entire heart. Dependent on the model, it may have several valves, a mechanism to propel the blood forward, and one or more chambers. The device is made from a combination of metals and plastics, and is fitted with a…

into the body. The blood vessel, vein, has the duty to deliver deoxygenated blood to the heart. The deoxygenated blood pass into the heart from the right atrium with the help of diastole then the deoxygenated blood goes to the right ventricle and the right ventricle has the duty to deliver the deoxygenated blood to the lungs through pulmonary artery and the with the help atria’s…
