Tumorablationis a minimally invasive medical procedure that allows for the treatment of certain types of cancer without requiring the surgical removal of unwanted cells. There are two primary forms of tumor ablation:cryoablationand thermal ablation. The success of this alternative form of cancerous tis...
Radiofrequency Catheter Ablation of the Anterosuperior and Posteroinferior Atrial Approaches to the AV Node for Treatment of AV Nodal Reentrant Tachycardia... Catheter Ablation Techniques in AVNRT. Radiofrequency catheter ablation has been established as a first-line curative treatment modality in patients...
AV node ablation: In this procedure, the doctor may insert a catheter into a vein near the thigh and slide it up to the AV node (a nerve that conducts electrical impulses between the top and bottom chambers of the heart). Radiofrequency energy is sent through the catheter to destroy the...
A 57-year-old man with nonischemic car-diomyopathy and permanent atrial fibrillation was implanted with a cardiac resynchronization therapy pacemaker (CRT-P) prior to an atrioven-tricular (AV) node ablation. The electrocardiogram prior to CRT-P implant showed a narrow QRS (duration 88 ms) but...
With respect to the mechanism that explains this block, it has been postulated that patients with low basal adenosine levels exhibit hyperaffinity of the A2 receptors of the AV node. Variations in plasma adenosine levels may favor episodes of paroxysmal AV block. The diagnosis of this block is ...
Twist1 expression in CAFs is related to tumor size, lymph node metastasis, and depth of invasion, as well as poor survival in patients with gas- tric cancer, especially in patients with diffuse-type gastric cancer. Besides gastric cancer, Twist can be expressed in both cancer cells and CAFs...
A separate indication for CRT is the pace/ablate strategy, which describes implantation of a CIED for bradytherapy followed by total AV node ablation, in patients who have had difficulty with AF rate control [47]. The APAF-CRT trial was an open-label, blinded outcomes trial where 133 patient...

What is a Nonconducted P wave? A nonconducted PAC resultswhen an ectopic atrial focus occurs so early that it finds the AV node refractory and the impulse is not conducted to the ventricles. This results in a premature, abnormal P wave not accompanied by a QRS complex, but followed by a...
Since it induces conduction block in the AV node, adenosine has diagnostic utility in patients with narrow QRS complex tachycardia. Similarly, adenosine could be of the most value in hemodynamically stable wide QRS tachycardia (WQRST) with 1:1 VA conduction when there is difficulty in ...
