Tachycardia, SV: During an episode of SVT, the heart's electrical system doesn't work right, causing the heart to beat very fast. The heart beats at least 100 beats a minute and may reach 300 beats a minute. After treatment or on its own, the heart usually returns to a normal rate of 60 to 100 beats a minute. SVT may start and end quickly, and you may not have symptoms. SVT becomes a problem when it happens often, lasts a long time, or causes symptoms. SVT also is called paroxysmal supraventricular tachycardia (PSVT) or paroxysmal atrial tachycardia (PAT). ...Read more

Age predicted HR: Maximum heart rates vary significantly between individuals. Even within a single elite sports team, such as olympic rowers in their 20s, maximum heart rates have been reported as varying from 160 to 220. Such a variation would equate to a 60 or 90 year age gap in the linear equations above, and would seem to indicate the extreme variation about these average figures. ...Read more

While i'm cycling in the morning my heart rate goes to as up as 175bpm with a average of 150bpm. It's that too dangerous or its normal?

Normal: Everyone has an intrinsic "maximal heart rate" which is different for each of us. During a strenuous workout, you may in fact want to get to 95% of your max heart rate. Unfortunately, without a max heart rate test, you don't know what that is. In any event, if you feel good about the effectiveness of your workouts then there is no cause for concern. ...Read more
