My Foolish Heart

Arteries Arteries carry blood at high pressure (80 - 120 mm Hg) They have a narrower lumen (to maintain high pressure) surround by a thick wall made of two layers The middle layer (tunica media) contains muscle and elastin to help maintain pulse flow (it can contract and stretch) The outer layer (tunica adventitia) contains collagen prevents the artery rupturing due to the high pressure blood flow Veins Veins carry blood under low pressure (<10 mm Hg) They have a very wide lumen (keeps…

Mr. T is a 55-year-old man with a history of Pre-diabetes mellitus (DM) and hypercholesterolemia who presents with a chief complaint of “pressure on the chest” that lasted 5 mins. Mr. T was in his usual state of health until three days ago when he felt a gradually increasing pressure on his chest as he was shoveling snow at 7:30 am. The discomfort caused him to immediately stop shoveling and the pain resolved on its own with rest within 2 to 3 minutes, and he has not experienced any discomfort…

Electromyography (EMG) is a diagnostic procedure to detect the muscle’s membrane depolarization. It can be used to determine the functions of different muscles during different movements. For this study, the question is which movements associate with large burst of the deltoid, shoulder muscle, activity. I hypothesis that shoulder abduction, when the palm is down, would produce high level of the deltoid activation, the highest amplitude of EMG. The subject performed four different movements with…

Summary of Clinical History: A 56 year-old obese male, living alone in Chicago, was found dead in his home. Patient presented with high blood pressure, high cholesterol, and gout. Feet were swollen and necrotic along with poor vision. High levels of ketones were found in the urine and toxicology reports came back with metformin, glyburide, and novolin-N in the system Description of Gross Lesions: External Examination: Respiratory System: I examined the trachea and saw it in good shape and…

They state investigations should include “alterations in maximal heart rate and maximal stroke volume, hemoglobin levels and endothelial function, and skeletal muscle characteristics” (Farrell & Willis, 2012). These variables could provide answers and understanding of how serum vitamin D affects the cardiorespiratory…

Although these drugs may help maintain a normal heart rhythm, they can cause side effects, including: nausea, dizziness, and fatigue. Rarely, they may cause ventricular arrhythmias – life-threatening rhythm disturbances originating in the heart’s lower chamber. These medications may be needed indefinitely. Even with medications, there is a chance of another episode of atrial fibrillation. The patient may be prescribed medications to control the heart rate and…

This patient is a 70-year-old male who required inpatient hospitalization due to concerns for acute exacerbation of congestive heart failure. He was presented to the emergency department due to the complaints of pain in the sub sternal/epigastric region accompanied by productive cough which worsen by movements. The pain was described as mild to moderate, constant and dull. His past medical history was suggestive of cardiomyopathy and hypertension. It was noted that he underwent cardiac…

to Childress and Liverman “a group study showed that the families of younger patients were more likely to consent to donation.” They also mention that consent was associated with deaths due to trauma. (Childress, Liverman 63). What I understand from my research on family consent is that the family is only allowed to make a decision on their family’s organ donation in critical and trauma cases. If the patient is already registered as in organ donor than the family isn’t allowed to make any…

The heart is comprised of four chambers, the right atrium, right ventricle, left atrium and the left ventricle. The right atrium is the chamber which receives blood from the body that has been depleted from its oxygen and pumps it to the right ventricle. The right ventricle then pumps the blood from the right atrium over to the pulmonary artery which as the name would suggest means it goes to the lungs and the oxygen depleted blood is once again oxygenated. The left atrium of the heart then…

These can involve sudden and intense pain in areas of the abdomen, dizziness, falling levels of blood pressure, rapid pulse, and loss of breath. 5.) Treatment(s): Source: British Heart Foundation.
