Therefore, occurrence of this condition in the left ventricle is because of impeded oxygen blood flow rather than oxygen content per cubic millimeter of blood (Mann, 2010).
5. Draw a normal ECG wave pattern and show how it relates to the action potentials of cardiac muscle cells. What causes the delay between the P. wave and QRS complex?
The delay between P. wave and QRS complex is attributed to the pause that causes the transmission of electrical impulse from the atria to the ventricles to take longer than expected.
6. What is a ventricular ectopic or estrasystole, what area its effect on stroke volume, and what might cause an extrasystole?
Extrasystole refers to the additional beat, or contraction, which causes an interruption in the standard rhythm of the heart rate, which is normally regular. It is caused by electrical discharge originating from other places of the heart rather than the normal sino-atrial node.
7. Are there any dangers in abruptly restoring blood flow to a tissue that has been ischemic for a long time?
It...
Here, the research suggests that "cardiac depression may also cause fluid to back up into the pulmonary system, resulting in pulmonary edema" (Aucoin, 2011, p 12). Moreover, increasing releases of aldosterone can also cause the body to retain fluid and sodium which can lead to endothelial dysfunction and organ fibrosis (Hobbs & Boyle, 2010). Other Systems Along with other systems, there is an impact on the thyroid as well when examining
Pathophysiology-Liver Disease The case study is of a 66-year-old man who has been drinking and smoking daily for 30 years. He admits to smoking two packs of cigarette per day and to drinking three glasses of brown alcohol daily for 30 years. Currently his family describes his behavior as erratic; he gets frustrated easily and gets quite aggressive at times. He visited his family doctor after a recent episode of hematemesis
2008). Indeed better screening is necessary due to the number of false-negatives from women with precancerous lesions among the most frequent reasons of medical malpractice in the United States (Steben, M. et al. 2007). In the case of having a tissue sample to be tested, early stage cervical cancer can be differentiated from healthy cervical tissue by gene expression profile due to comparisons done with healthy and lymph node metastatic
The digestive fluids that are secreted by the stomach glands aimed at breaking down solid food and to kill bacteria in the stomach are referred to as gastric juices. Gastric acid is produced by the gastric parietal cell located on the walls of the stomach. The region where the gastric juices are secreted into the lumen is the most acidic environment in the human body and is known as the
Pathophysiology of Gastric Acid Stimulation and Production The human body produces gastric acid in the stomach, primarily to digest proteins (Anand, 2015; Huether & McCance, 2012). It is composed o hydrochloric acid and sodium chloride. It digests proteins through the action of digestive enzymes and allowing digestive enzymes break down the long chains of amino acids from digested proteins. The production of gastric acid us regulated by the autonomous nervous system
Pathophysiology of Asthma Asthma is a common respiratory disease believed to be influenced or determined by genetic and environmental factors, such as allergens and respiratory viruses (Chung & Adcock, 2001). Asthma can be acute, chronic or fatal. It is acute when it is severe and sudden (Hadjlladis, 2014), chronic when it develops for a long period of time, and fatal, when it leads to death. An acute first asthmatic attack can
