ReviewIndications for pacing in patients with congenital heart disease.
Advances in pacing technology have increased indications for antibradycardia pacing and new indications have appeared for treatment of atrial tachycardia and cardiac failure in patients with congenital heart disease (CHD). ⋯ Cardiac pacing indications have extended beyond prevention of sudden death and pacemaker implantation is now indicated to improve quality of life of patients with CHD and as a bridge to cardiac transplantation.

Case ReportsRight ventricular perforation with an ICD defibrillation lead managed by surgical revision and epicardial leads--case reports.
The authors present two cases of patients with perforation of the right ventricular wall by the implantable cardioverter defibrillator (ICD) lead. The complication was resolved by cardiosurgical revision and epicardial leads stitched onto the diaphragmatic wall of the heart. ⋯ Both patients had satisfactory values of electrical parameters and ICD function with epicardial leads. The importance of regular follow-up and a check of the lead parameters are emphasized.

Correlation between QTc interval and clinical severity of subarachnoid hemorrhage depends on the QTc formula used.
Subarachnoid hemorrhage (SAH) frequently prolongs QT interval in the acute phase. The purpose of our study is to investigate whether the correlation between electrocardiographic corrected QT interval and the clinical severity of SAH depends on QTc formula used. ⋯ In our study, correlation between QTc interval and clinical severity of SAH depended on the QTc formula used.

Clinical TrialNavigation by parallax in three-dimensional space during fluoroscopy: application in guide wire-directed axillary/subclavian vein puncture.
Fluoroscopy is range ambiguous--the relative positions in three-dimensional space of two structures with superimposed silhouettes cannot be ascertained. The parallax effect can be used to overcome this problem, and was used to develop a technique of axillary/subclavian vein puncture. ⋯ The new technique was effective, efficient, and safe when implemented in clinical practice, justifying the parallax principles on which it is based. The parallax principles may be applied to other invasive medical procedures with due modifications.

Case ReportsDexmedetomidine related cardiac arrest in a patient with permanent pacemaker; a cautionary tale.
Dexmedetomidine (Precedex), an alpha-2 adrenergic receptor agonist is frequently and safely used as sedative agent during surgical procedures. We report a case of a 76-year-old woman who developed cardiac arrest from the use of dexmedetomidine during pacemaker lead extraction procedure.
