BACKGROUND Anticoagulation in patients undergoing atrial fibrillation (AF) ablation is crucial to minimize the risk of thromboembolic complications. There are broad ranges of approaches to anticoagulation management pre and post AF ablation procedures. The purpose of this study was to determine the anticoagulation strategies currently in use in patients(More)
The QT interval in the electrocardiogram (ECG) is a measure of total duration of depolarization and repolarization. Correction for heart rate is necessary to provide a single intrinsic physiological value that can be compared between subjects and within the same subject under different conditions. Standard formulas for the corrected QT (QTc) do not fully(More)
A method of ventilation utilizing an S-shaped cannula placed through the cricothyroid membrane and hooked up to a conventional jetting system is described. Its advantages are reduced morbidity, better ventilation, and an unobstructed view of the operating site for the surgeon. The system allows ventilation of the patient with oxygen prior to the induction,(More)
Using B-mode transcranial sonography (TCS), it is possible to image the brain parenchyma through the intact skull with conventional low-frequency probes. Several brain disorders can be depicted by TCS such as bleedings, brain tumors, or enlargement of the ventricular system. More recently there is evidence that TCS findings can complement information from(More)
Analysis of T waves in the ECG is an essential clinical tool for diagnosis, monitoring, and follow-up of patients with heart dysfunction. During atrial flutter, this analysis has been so far limited by the perturbation of flutter waves superimposed over the T wave. This paper presents a method based on missing data interpolation for eliminating flutter(More)
BACKGROUND AND PURPOSE Measurement of QT intervals during atrial flutter (AFL) is relevant to monitor the safety of drug delivery. Our aim is to compare QT and QTc intervals in AFL patients before and after catheter ablation in order to validate QT measurement during AFL. METHODS 25 patients suffering from AFL underwent catheter ablation; 9 were in sinus(More)
Studies carried out in the laboratory have shown that an S-shaped cannula for trans-laryngeal jet ventilation provides a distinct advantage over conventional straight ones. Tidal volumes are larger and the cannula is more stable in position. The tendency of perforate the posterior wall of the trachea during introduction is also minimal. Blood gas data(More)
