…we used to set pacemakers at 72 bpm. But before getting a pacemaker, you want to make sure your doctor rules out other causes of these symptoms such as the use of beta blockers or a heart block. * Anyone with heartbeat pauses of 3 seconds or more should be evaluated for a pacemaker. This can be measured…
Today, I want to tell you about a couple of other build-in pacemakers. We'll start with the atrioventricular or AV node. Like our discussion of the SA node, the discussion is pretty technical. Look at it as a way to impress people around the watercooler! The AV node is a "back up" for the SA node. Should…
…pressure is the cause. But it can also happen in people with arteriosclerosis, valvular disease, congestive heart failure, atrial fibrillation, and pacemaker therapy. The classic signs of VaD are slowed thinking, memory problems, confusion that often worsens at night, personality changes, loss of social…
…cordless phones—which can be a real danger to your pacemaker and your heart. The same danger exists for folks with intra-cardiac defibrillators (ICDs). The reason is that your heart is more than a muscle; it’s a finely tuned electrical system. Pacemakers and ICDs are inserted when the heart needs help…
…her to rule out a stroke, or low heart rate. And while she was surprisingly hypertensive on admission and her heart rates low enough to validate a pacemaker, her failing memory has yet to improve since she's been discharged home again. So, in addition to her two siblings, my mother also has dementia. Because…
…left ventricle, and then the aorta, circulating oxygen-rich blood throughout your body. What happens with AF is the heart’s normal electrical "pacemaker" is bombarded by competing electrical charges, which originate in the atria—hence the name, atrial fibrillation. These competing impulses initiate…
Most people are familiar with the artificial pacemakers that we use to keep the heart beating, but many don’t realize that the heart has built-in pacemakers of its own. Every cardiac cell is capable of automaticity (to fire on its own) and conductivity, but there is a specialized network in charge…
Recently, a reader on my blog asked me for the typical and atypical signs of atrial fibrillation (AF). That’s a good question because some people have AF and don’t know it. Yet, if left untreated it can cause long-term complications. Here’s why… AF is an irregular heartbeat caused when the…
