can maintain electrical function in damaged regions of the heart. Until now, scars in the heart were thought to only disrupt the electrical activity needed for a normal heart beat. The finding was recently published inProceedings of the National Academy of Sciences. ...
Catheter electrical ablation using a relatively low level of energy--40 to 100 joules--was attempted in 12 consecutive patients with drug-refractory sustained ventricular tachycardia (VT). They had 19 monomorphic VTs, and ischemic heart disease was found as the underlying heart disease in one, non...
This study investigated the mechanisms and long-term outcomes of AT and AF ablation after various Maze procedures, particularly whether atrial tachyarrhythmias after the Maze procedure occur due to gaps in the Maze lines. We analyzed 37 consecutive cases with atrial tachyarrhythmias after the Maze ...
(EMG). The ECG is the simplest of the detection of electrical signals from our heart to check its condition. To measure the electrical activities in our brain we utilized the EEG procedure. EMG, on the other hand, is mostly utilized to gather electrical signals from our body muscles. The ...
Programmed electrical stimulation(PES), introduced in 1972 for diagnostic purposes, evolved into a procedure utilized for clinical management of patients with life-threatening VTs. The results of a typical study are examined in terms of: (1) the presence orabsenceof inducible arrhythmia; (2) the ...
This technique may help in planning ablation procedures, avoiding unnecessary interseptal punctures for right-to-left frequency gradients cases and facilitating the targeting of the AF drivers, reducing risk and time of the clinical procedure. 展开 ...
d Control procedure of the electro-ablation surgery under magnetic control. e The catheter-style soft surgical tool performs precise ablation of predefined points (the minimum distance is 1 mm) on porcine tissue in an enclosed space under the control of an actuation magnetic field. f ...
heart failure (HF). Anti-arrhythmic drugs (AADs) have considerable side effects and modest efficacy. Invasive radiofrequency catheter ablation (CA) identifies electrically reentrant regions within scar and delivers ablative thermal energy to homogenize scar and eliminate VT2. However, CA is time-...
1. At the end of the ablation procedures, 23 patients underwent programmed electrical stimulation. In 2 of those patients, non-clinical VTs were inducible. There was no inducible clinical VT at the end of the procedure. Five patients (17.9%) were not tested due to haemodynamic instability ...
This structure was reported to confer excellent electrical and mechanical properties to Y2O3/Ag electrical contact materials, particularly enhancing arc resistance against ablation. Li et al. [26] investigated the impacts of the SnO2 particle size on the properties of SnO2/Ag electrical contact ...
