Active clinical trials for "Bradycardia"

This a prospective study when the clinician decides to use sugammadex, heart rate will be recorded every minute for 15 minutes following its administration. If bradycardia occurs and a clinical decision is made to treat it, the medications and doses used will be recorded.

This study will collect data on features for future pacemakers via an external non-implantable system.

This registry is a data collection on patients who are implanted for more than 6 months with a pacemaker. Frequency and distribution of right ventricular pacing, NYHA class and left ventricular ejection fraction shall be documented.

This study shall evaluate in daily medical practice the clinical results of the AV delay hysteresis search algorithm in patients with a INSIGNIA ULTRA or AVT pacemaker implanted for one of the three following indications: sinus node dysfunction, atrial disease (or bradycardia/tachycardia) and atrio-ventricular paroxysmal block. In addition use and outcome of automatic functions will be evaluated.

The purpose of this study is to collect data from pacemakers and determine how this information is used by physicians to care for their patients with pacemakers.

Observational study to determine if topical anesthetic and intraoperative oculocardiac reflex influence post strabismus surgery recovery.

The aim of the submodule study is to assess whether a high BMI may influence the sensing performance and the sECG quality of the BIOMONITOR.

Prospective, non-randomized, multi-center study designed to quantify patient preferences pertaining to risks and features of conventional transvenous pacemakers and leadless pacemakers

Pulling the eyeball during ophthalmic surgery provokes decrease in heart rate. This phenomenon is called oculocardiac reflex. In some patients asystole may occur. Other cardiac features of this reflex include hypotension, dysrhythmias, atrioventricular block. These cardiovascular disturbances may lead to decreased perfusion and ischemia of vital organs. Patients with existing cardiovascular disease are in risk of complications. Cardiovascular system is mainly innervated with autonomic nervous system (ANS). Sympathetic/parasympathetic activity may be determined by Heart Rate Variability (HRV). HRV analysis based on short 5 minutes electrocardiography has been found useful for prediction of hypotension and bradycardia during induction of general anaesthesia and during spinal block. The aim of this study is to verify whether it is possible to predict oculocardiac reflex with the use of HRV analysis for ANS activity assessment, measured prior to the ophthalmic surgery.

The purpose of the study is to demonstrate that reduction of unnecessary pacing provided by RYTHMIQ algorithm programed to ON in a pacemaker is associated with better clinical outcomes in bradycardia target population.
