How is SVT diagnosed on ECG?

Supraventricular tachycardias are usually narrow-complex tachycardias with a QRS interval of 100 ms or less on an electrocardiogram (ECG). Occasionally, they may show a wide QRS complex in the case of a pre-existing conduction delay, an aberrancy due to rate-related conduction delay or a bundle branch block.

What diagnosis is SVT?

Supraventricular tachycardia (SVT) is as an abnormally fast or erratic heartbeat that affects the heart’s upper chambers. An abnormal heartbeat is called an arrhythmia. SVT is also called paroxysmal supraventricular tachycardia.

Is SVT dangerous?

SVT is also known as paroxysmal supraventricular tachycardia (PSVT) or paroxysmal atrial tachycardia (PAT). People with SVT may go into this arrhythmia from time to time unrelated to exercise, stress or other common causes of a rapid heart rate. For most people, SVT is not dangerous.

Are SVTs serious?

SVTs are one of the most frequent causes of emergency department and physician office visits. 5 Although most cases of SVT are not considered to be dangerous or life threatening, frequent episodes can weaken the cardiac muscle over time, and should therefore be addressed with medical…

What is supraventricular tachycardia?

Supraventricular tachycardia. Overview. Supraventricular tachycardia (SVT), also called paroxysmal supraventricular tachycardia, is defined as an abnormally fast heartbeat. It’s a broad term that includes many forms of heart rhythm problems (heart arrhythmias) that originate above the ventricles (supraventricular) in the atria or AV node.

What is the location of an EKG?

Electrode placement for a 12-lead ECG is standard, with leads placed on the left and right arm and left and right leg. Another pair of electrodes is placed between the fourth and fifth ribs on the left and right side of the sternum.
