The Effects of Drugs on Cardiac Physiology

Lab Report The effectuate of Drugs on Cardiac Physiology The deal hold of of cardio physiology was broken up into five distinct recrudesces both centering on the cardiovascular system. The first lab was strong-arm exercise of the cardiogram (ECG). This studied the electrical activities of the marrow by placing electrodes on contrasting parts of the skin. This results in a graph on calibrated paper of these activities. These graphs are usable in the diagnosing of midsection disease and snapper abnormalities. Alongside native nerve centre abnormalities are those induced by chemical substances. The electrocardiogram is useful in showing how these chemicals adjust the electrical impulses that it induces. The plump for part of this lab was a computer simulation computer program to expand a frogs electrocardiogram utilise confused drugs in an isolated treatedting. The computer program authorize Effects of Drugs on the Frog Heart allowed experimental conditions to be set for specific drugs. The different drugs used were calcium, digitalis, pilocarpine, atropine, potassium, epinephrine, caffeine, and nicotine. Each of these drugs caused a different electrocardiogram and beats per minute reading. The calcium-magnesium ration affects the permeability of the cadre membrane(Fox).

When calcium is placed directly on the shopping center it results in three physiological functions. The force of the internality increases period the cardiac rate decreases. It also causes the appearance of ectopic pacemakers in the ventricles, producing abnormal rhythms (Fox). Digitalis affect on the heart is actually similar to that of calcium. It inhibits the sodium-p! otassium pump activated by adenosine triphosphate that promotes the intake of extracellular calcium by the heart. This in regress strengthens myocardial contraction (Springhouse). Pilocarpine on the former(a) hand acts to decrease the heart rate. It achieves this by assisting in the release of acetylcholine from the vagus nerve. Atropine on the other(a) hand block acetylcholine receptors thus decreasing cardiac rate.
