Differences in Cardiovascular Fitness that Effect Nonsmokers and Smokers Kayla Forbes 2-15-12 Bio Lab 140/77 Hilde Stawski Abstract: The goal of this experiment was to find out how smoking affected nonsmokers‚ light smokers‚ and heavy smokers heart rate during cardiovascular endurance. The participants will record their pulse rate before and after every minute for six minutes after the step test. As predicted‚ the heavy smokers had an increase in pulse rate that was twice as high as the

* GROUP 2: Elrey Joseph Calitis Mae Anjneth Cuaton How Atrial Tachycardia happens? Electrical signals in the heart’s upper chambers fire abnormally‚ which interferes with electrical signals coming from the sinoatrial (SA) node --- the heart’s natural pacemaker. A series of early beats in the atria speeds up the heart rate. The rapid heartbeat does not allow enough time for the heart to fill before it contracts so blood flow to the rest of the body is compromised. Video Presentation
