What is Tachycardia?
Tachycardia is a condition where your heart beats very rapidly–usually more than 100 beats per minute, but it is not from exercise or any normal external stimuli. Tachycardia starts in the upper chambers (the atria) or the lower (ventricles) of your heart. If you experience symptoms of tachycardia, you need to see your doctor right away for a proper diagnosis, because its effects don’t just stop at a rapid heartbeat. Atrial and Ventricular Tachycardia Atrial fibrillation (the most common) is experienced by some 2.2 million Americans age 75 or older, according to research done by the Sarver Heart Center. Impulses travel in a rapid but disorganized manner through your heart’s atrium, then down into the ventricles causing irregular, rapid heartbeats. With atrial fibrillation you are at risk for a stroke. Atrial flutter is similar to atrial fibrillation except that the impulses are semi-organized instead of disorganized. Atrial flutter also carries some risk of stroke. Supraventricular ta
