Radiofrequency (RF) ablation of atrial fibrillation (AF) can be accompanied by pain and anxiety when light conscious sedation is used. We sought to determine how visualization and structured attentive behavior during ablation of AF could reduce pain intensity, spontaneously expressed pain, the amount of analgesics, anxiety, and adverse events. A clinical controlled study with 71 patients in a control group (CG), receiving conventional care and treatment, and 76 patients in an intervention group (IG), receiving relaxation and visualization, combined with a structured attentive behavior from staff. There was no difference between CG and IG in perception of pain intensity at 15-minute intervals; mean pain intensity: CG (0.00-2.90), IG (0.12-2.57), (NS), but patients spontaneously expressed pain less numbers of time outside fixed intervals in the IG: 1.4 ± 1.2 times (mean ± standard deviation [SD]) compared to CG: 2.8 ± 1.8 (P < 0.01). There was a statistically significant difference between the amount of analgesics (Fentanyl) used in the two groups: CG: 292.3 ± 107 μg (mean ± SD) and IG: 220.7 ± 93 μg (P < 0.0001). No effect was observed in perception of anxiety, mean anxiety: CG (0.10-1.84), IG (0.9-2.03)(NS), and the number of a...Continue Reading

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.
