At 32 Canadian heart centers, a group of physicians performed a study on the effects between physiologic pacing (dual chamber or atrial) and single chamber pacing (ventricular). The researchers were trying to determine whether the physiologic pacing is superior to the single chamber pacing as previous thought. The way they would determine this is to take a sample of patients that will receive one of the above pace makers and compare the results of atrial fibrillation, stroke, or death due to the heart. The researchers gathered their sample by some specific criteria. A total of 7734 patients received a first pacemaker at one of the 32 participating clinics, of these patients only 4499 qualified to participate. After gathering the total group

The mean age of these patients was 71. Also, 49 percent had symptoms of heart failure class II and above, according to New York Heart Association. After researchers did some baseline test with the 2568 patients, they put them into two groups. 1474 were assigned single chamber pacing, while 1094 were assigned physiologic pacing. The reason for the unequal amount is due to a randomized ratio to balance both groups that are categorized as following; mean age, gender, >class II functional heart failure, indication for pacing, medical history, medications, left ventricular function, and symptoms of bradycardia. In each group, they strived to get an equal baseline characteristic to ensure a valid …show more content…
I feel like this article follows up very well with chapter 18 and lab 30. As, I am familiar with the structures and terminology which helps me follow and understand what was going on. Also, pacemakers are a device that really intrigues me. It is amazing how we have made man-made objects to artificially make an organ work, especially something as important as the heart. This article could also benefit me one day, my Dad got a pacemaker at the age of 40. It was due to genetics, which makes me more cautious and aware to take care of my heart. Hopefully not, but if I must get a pacemaker I am now more educated on the different
