In this situation, the P-wave morphology in leads V1 and II plays a decisive role. The P wave of sinus rhythm is biphasic (initially positive, then negative) in V1, with or without left atrial ...

A new multicenter trial has used a new ablation technique for patients with ventricular tachycardia, an abnormally rapid heart rhythm that is a leading cause of sudden cardiac death worldwide. A first ...

Supraventricular tachycardia is a term used to describe any heart rhythm that is greater than 100 beats per minute originating from above the AV node (the atrium). The term “SVT” can be confusing at ...

Sinus tachycardia is a heart rate that is faster than normal, and it can be triggered by exercise, stress, or anxiety. However, it may also indicate an underlying health problem. Symptoms of sinus ...

Atrial tachycardia and other ectopic atrial rhythms occur when a site outside of the sinus node, but within the atria, creates action potentials faster than the sinus node. This ectopic focus becomes ...

Sinus rhythm is the term for the regular pattern of heartbeats driven by the heart’s natural pacemaker, the sinus node. Variations like sinus tachycardia (fast heart rate) and sinus bradycardia (slow ...

A first-in-human multicenter trial involving Mayo Clinic has used a new ablation technique for patients with ventricular tachycardia, an abnormally rapid heart rhythm that is a leading cause of sudden ...

Tachycardia refers to a fast resting heart rate, usually over 100 beats per minute (bpm) in adults. Some people experience no symptoms, but others may notice palpitations and lightheadedness, among ...

Ventricular tachycardia (V-tach or VT) is when the lower chamber of the heart beats too fast to pump efficiently. This reduces the amount of oxygenated blood the rest of the body receives. VT is a ...

If you have ventricular tachycardia, your doctor may give you medicine to slow your heart rate down. You might also need a catheter ablation. In this procedure, a doctor threads a thin tube through an ...

Tachycardia and bradycardia are two types of irregular heart rates. Tachycardia is when the heart beats faster than 100 beats per minute. Bradycardia is when the heart beats slower than 60 beats per ...
