Multicenter Study Observational Study
Effectiveness of remote monitoring of CIEDs in detection and treatment of clinical and device-related cardiovascular events in daily practice: the HomeGuide Registry.
The HomeGuide Registry was a prospective study (NCT01459874), implementing a model for remote monitoring of cardiac implantable electronic devices (CIEDs) in daily clinical practice, to estimate effectiveness in major cardiovascular event detection and management. ⋯ Home Monitoring was highly effective in detecting and managing clinical events in CIED patients in daily practice with remarkably low manpower and resource consumption.

The indications for implantable cardioverter-defibrillators (ICDs) have been expanding, especially for primary prevention of sudden cardiac death. Implantable cardioverter-defibrillator saves lives; however, in near end-of-life situations linked to incurable diseases, the question arises as to whether or not to turn off the ICD to avoid excessive numbers of shocks as the heart begins to fail. This study examined the wishes of a cohort of ICD recipients. ⋯ Most ICD recipients felt safer following ICD implantation and most wanted more information regarding ICD deactivation. However, a significant number of patients (especially, secondary prevention patients) had no interest in receiving additional information about this topic.

A high prevalence of prolonged QT interval duration has been observed among haemodialysis (HD) patients. The aim of this cases series was to describe the association of various risk factors with total mortality and sudden cardiac death (SCD) in this population. ⋯ In a case series of HD patients, QTc was associated with total mortality and SCD. Further studies to test this hypothesis in a larger population are necessary.

Comparative Study Clinical Trial
Effects of deep sedation on cardiac electrophysiology in patients undergoing radiofrequency ablation of supraventricular tachycardia: impact of propofol and ketamine.
Propofol is commonly used as an anaesthetic during catheter ablation. Bradycardia and termination of supraventricular tachycardia (SVT) under propofol are reported. Ketamine is used for cardiac catheterization procedures and increases heart rate and blood pressure. Our study aimed to determine the effects of propopfol and ketamine on atrial electrophysiology. ⋯ Our results show stimulatory effects of ketamine on heart rate, atrial conduction, and blood pressure. Ketamine, therefore, may be beneficial in patients with pre-existing hypotension and bradycardia.
