congested. This is then called congestive heart failure. 2. What is third-degree heart block? What would the EKG tracing of someone with third-degree heart block look like? Third-degree block‚ also known as third-degree atrioventricular block is “a cardiac conduction system where there is no conduction through the atrioventricular node” (Budzikowski 2014). The patient will have severe bradycardia with independent atrial and ventricular rates. These patients may suffer from ventricular standstill‚ which

Chapter 1 - The Human Body Anatomy is the science relating to the structural organisation of living organisms. Physiology is the science relating to the operational functions of living organisms. The many parts and systems of the body are integrated and function co-operatively to provide a healthy living body via 6 hierarchy levels of structural organisation. The basic or first level is the Chemical Level‚ where atoms are combined to form molecules. The second level is the Cellular Level

of the requirement for the fourth year of B.Sc. Nursing Programme. We were provided 8 weeks of the clinical practice‚ at Shahid Gangalal National Heart Center. During our 8 weeks of clinical exposure each student had to do a detailed study of one cardiac problem. During my clinical exposure to Coronary Care Unit (CCU) for 1 week I got an opportunity to take case for study. We had morning‚ evening and night duty for complete exposure to clinical picture. Regarding this process‚ I would like to express

This is made possible by his bicep relaxing and his tricep contracting to make his arm straight. This function is not evident in either cardiac or smooth muscle. Type 1 muscle (slow twitch oxidative) is evident in many Athletes such as long distance runners‚ cyclists and long distance swimmers. This is because these athletes have a high demand of oxygen in their muscles and need their muscles

What is athletic training? Athletic training is the concern of the well being of the athlete and generally assumes the responsibility for overseeing the total health care for the athlete. This basically states that an athletic trainer’s job is to be there for the athlete whether he/she is injured or not‚ and to practice the prevention of injury. By learning the proper techniques and steps to stretching‚ an athletic trainer can pass that information onto the athlete to help prevent common problems

stimulation caused the heartbeat to flat line and then restart and react normally. 2. Soon after you applied the stimuli‚ did the heart rate increase or decrease? Soon after the stimulus is applied the heart rate decreased. 3. Why? This is because the cardiac muscle cells depolarize. 4. How do the sympathetic and parasympathetic nervous systems work together to regulate heart rate? Sympathetic neurons increase the heart rate while the parasympathetic neurons decrease the heart rate and the heart simultaneously

The heart is a muscular organ that pumps blood through the body via the circulatory system. In vertebrates the heart consists of two chambers called the atria and ventricles. The atria (upper chamber) receives the blood returning to the heart and the ventricles (lower chamber) pumps the blood away from the heart. The atria and ventricles chambers are separated by four main valves called the atrioventricular (two valves)‚ pulmonary‚ and aortic valves. These valves help create the heart sounds often

department‚ an ECG and cardiac enzymes were obtained. The cardiac monitor showed sinus tachycardia with occasional premature ventricular complexes. K.R. was treated with 2 L nasal oxygen‚ tissue plasminogen activator‚ sublingual nitroglycerin‚ and IV morphine sulfate. When he was pain free‚ he was transferred to the cardiac unit for monitoring. Discussion Questions 1. What changes in “cardiac enzymes” would be consistent with a diagnosis of MI? Troponins(I and T specific to cardiac muscle cells)‚ elevated
