tachycardia


Tachycardia is a condition that makes your heart beat more than 100 times per minute. There are three types of it: Supraventricular. This happens when the electrical signals in the organ's upper.



Sinus tachycardia is an increase in the heart rate. In this condition, the heart’s natural pacemaker, the sinus node, sends out electrical signals faster than usual. The heart rate is faster than normal, but the heart beats properly. It’s a common response to exercise, but it’s concerning when it occurs at rest.



Other potential causes of normal sinus tachycardia include: stimulants, such as nicotine or caffeine alcohol anxiety stress low blood pressure infection



Atrial tachycardia is a fast heartbeat (arrhythmia). It's a type of supraventricular tachycardia (SVT). During an atrial tachycardia episode, the heart rate increases to more than 100 beats a minute before returning to a typical heart rate of around 60 to 80 beats a minute. An episode may start gradually or it may start abruptly.



Ventricular tachycardia (V-tach or VT) is a fast heart rate arising from the lower chambers of the heart. Although a few seconds of VT may not result in permanent problems, longer periods are dangerous; and multiple episodes over a short period of time are referred to as an electrical storm.



TWENTY-TWO years ago in the Journal, the term "multifocal atrial tachycardia" was first applied systematically to an arrhythmia characterized by irregularity, different forms of P waves, and (in.
