Cardio Physiology Lab Report
The study of cardio physiology was broken up into five distinct parts all centering on the cardiovascular system. The first lab was utilization of the electrocardiogram (ECG). This studied the electrical activities of the heart by placing electrodes on different parts of the skin. This results in a graph on calibrated paper of these activities. These graphs are useful in the diagnosis of heart disease and heart abnormalities. Alongside natural heart abnormalities are those induced by chemical substances. The electrocardiogram is useful in showing how these chemicals adjust the electrical impulses that it induces.
The second part of this lab was a computer simulation program to illustrate a frog’s electrocardiogram using various drugs in an …show more content…
The earpieces on the stethoscope were first cleaned with the alcohol swabs. The diaphragm was then placed on the bicuspid area to hear the heart sounds. Also, the diaphragm was placed on the aortic and pulmonic areas. During these three auscultations, the heart sounds were compared during quiet breathing, slow and deep inhalation, and slow exhalation. The results were recorded.
Focus was then switched to blood pressure. The subject sat on a chair with their left arm resting on a table. The blood pressure cuff was wrapped just above the elbow. The diaphragm of the scope was then placed at the site on the cuital fossa where the arterial pulse was felt. The valve was screwed shut and the pump pressure was pumped until no sounds were heard. The screw was slightly loosened allowing the air to slowly come out. The first sound (systole) was recorded and when the sound …show more content…
Again, no noticeable difference is observed. Nicotine slows the heart rate down. The most likely is caused by nicotine binding to nicotinic receptors. This activates the parasympathetic neuron that causes a slowing of the heart rate. It ECG is most comparable to that of calcium and digitalis due to the effect of slowing heart rate.
Another way of studying the heart is through careful auscultating. In this particular lab, the heart sounds were listened to. No difference was noted during the different breathing patterns. This could very well be the cause of an untrained ear and of low quality stethoscopes. These two are both necessary in order to correctly perform the
