What is the difference between supraventricular tachycardia and ventricular tachycardia?

What is the difference between supraventricular tachycardia and ventricular tachycardia?

The many forms of tachycardia depend on where the fast heart rate begins. If it begins in the ventricles, it is called ventricular tachycardia. If it begins above the ventricles, it is called supraventricular tachycardia.

How do you fix ventricular tachycardia?

Sustained ventricular tachycardia often requires urgent medical treatment, as this condition may sometimes lead to sudden cardiac death. Treatment involves restoring a normal heart rate by delivering a jolt of electricity to the heart. This may be done using a defibrillator or with a treatment called cardioversion.

What causes a Bigeminal rhythm?

Bigeminal rhythms may arise from ectopic firing or from failure of impulse generation or conduction. In atrial bigeminy a premature atrial beat beat follows each sinus beat. If the PAC is not conducted bradycardia may result; if it is symptomatic treatment with digitalis or quinidine is indicated.

What does it mean to have ventricular tachycardia?

What is ventricular tachycardia? Ventricular tachycardia (VT or V-tach) is a type of abnormal heart rhythm, or arrhythmia. It occurs when the lower chamber of the heart beats too fast to pump well and the body doesn’t receive enough oxygenated blood.

What is the medical term for repetitive ventricular rhythms?

Repetitive ventricular rhythms at slower rates are called accelerated idioventricular rhythms or slow VT; they are usually benign and are not treated unless associated with hemodynamic symptoms. Most patients with VT have a significant heart disorder, particularly prior myocardial infarction or a cardiomyopathy.

What is the cutoff rate for ventricular tachycardia?

Ventricular Tachycardia (VT) Some experts use a cutoff rate of ≥ 100 beats/min for ventricular tachycardia (VT). Repetitive ventricular rhythms at slower rates are called accelerated idioventricular rhythms or slow VT; they are usually benign and are not treated unless associated with hemodynamic symptoms.

Are there any other treatments for ventricular tachycardia?

Ablation of ventricular tachycardia has a long history of safety and success. For some patients, ablation completely cures the abnormal rhythm, and no other treatment is needed. Ablation can also improve treatment with an implantable cardioverter defibrillator.
