Filter by:This prospective study was conducted in 268 patients aged from 65-70 years posted for coronary artery bypass grafting. Patients were randomly allocated to either adenosine or verapamil(control) groups. In the adenosine group, patients received IV adenosine 6 mg bolus then wait 2 minutes, if it failed to return to sinus rhythm then another 12 mg IV bolus of adenosine was administered, if supraventricular tachycardia persisted then the patient was shifted to verapamil. In verapamil group, patients received IV verapamil 5mg bolus slowly over 2 minutes followed by a second IV bolus dose of 5 mg ,10 minutes after the initial dose in case of persistence of supraventricular tachycardia (SVT). If SVT persisted, the patient was shifted to adenosine. The efficacy of the study drug, ICU stay length, systolic blood pressure, hospital- stay length, duration of extubation, the total dose of the study drug used, the total cost of the study drugs and the incidence of adverse events were recorded.
Supraventricular tachycardia (SVT) is an abnormally fast heart rhythm arising from improper electrical activity in the upper part of the heart. SVT is commonly treated with adenosine using three different IV administration techniques. However, it is not well known which of these three techniques is the quickest or most likely to reach the heart in order to stop SVT. This study will simulate each of those techniques in an investigator-blinded procedure. Intravenous agitated saline, used as a surrogate for a dose of adenosine, will be administered to healthy volunteers using all three techniques and monitored using bedside ultrasound to observe their efficacy and speed in reaching the right side of the heart.
• Supraventricular tachycardia (SVT) is defined as an abnormally rapid heart rhythm originating above the ventricles. It usually has narrow complex tachycardia but this is not always the case. Conventionally, atrial flutter and fibrillation are excluded from this group.ventricular tachycardia is the most common rhythm disturbance seen in children.(2) Most general practitioners will deal with a case at some point. While in most cases ventricular tachycardia can be considered a benign rhythm disorder, special consideration needs to be given to infants, athletes and patients with Wolff-Parkinson-White syndrome.
The aim of the study is to develop and validate a novel esophageal mapping system to improve the diagnostics of cardiac arrhythmias. Using a newly designed esophageal ECG catheter, esophageal ECGs (eECGs) will be recorded in 40 patients during an electrophysiological (EP) study and/or ablation procedure and in 12 healthy volunteers. In parallel acquired intracardiac electrograms will serve as reference for the developed mapping systems accuracy. Additionally, the esophageal mapping system will be compared to that of the standard 12-lead surface ECG in regard to its diagnostic performance.
The supra ventricular tachycardia is the most common symptomatic arrhythmia in pediatrics. Amiodarone is an antiarrhythmic drug used in this indication. Pharmacokinetic, efficacy and safety data are not known in the pediatric population due to the lack of a suitable specialty available on the market. The development of an amiodarone oral solution formulation adapted to this age group should provide a therapeutic alternative and collect data on the pharmacokinetics, efficacy, acceptability and tolerability of the drug.
The purpose of this research is to test the clinical value of a new P-wave sensitive recording vector compared to a standard ECG limb lead II vector from similar easy-to-use long-term cardiac rhythm monitoring patch systems, the Carnation TM Ambulatory Monitoring (CAM) System and the Zio-XT iRhythm. The P-wave is a critical aspect of the electrocardiogram. The purpose of this study is to see if the P-wave centric focus of the CAM system improves arrhythmia diagnosis.
The goal of this study is twofold. First the investigators would like to determine the trajectory of troponin leaks; if it can be shown that the participants who have only minimal elevations of their repeat troponin universally decrease on the 3rd level then future patients may see significantly improved length of stay. Second, given conflicting results in the literature, the investigators would like to determine if elevated troponin levels correlate to later cardiovascular complications. These complications will be defined as Death, Myocardial Infarction, Cardiovascular intervention (such as coronary artery stenting or bypass). As the investigator is a single hospital system in this county it is uniquely positioned to be able to review this retrospectively.
