To Validate the Specific Patterns of Magnetocardiography, a Non-invasive Non-contact Examination for Patients With Ischemic Heart Disease or Cardiac Arrhythmia

ECG is one of the most important non-invasive method to diagnose CAD and arrhythmia. However, clinically it still has its limitation. Because the electrical field could induce a magnetic field, the newly developed non-contact technique, magnetocardiography, was established to detect the local magnetic field component of the heart. It is safe and more convenient. In this study, we try to define and validate the magnetocardiographic patterns in the patients with cardiac arrhythmi...

The Value of add-on Arrhythmia Surgery in Patients With Atrial Fibrillation Undergoing Cardiac Surgery

The hypothesis being studied is that add-on arrhythmia surgery in patients with atrial fibrillation (AF) undergoing valvular or coronary surgery improves quality of life, is cost-effective, reduces perioperative and long-term morbidity associated with AF.

Electrophysiology of Fetal Arrhythmia

Fetal research and clinical practice has been hampered by a lack of suitable investigational techniques. Currently, ultrasound is the only widely used method of studying fetal anatomy and physiology, but it has significant limitations for assessment of cardiac rhythm. The proposed study will allow us to investigate fetal magnetocardiography (fMCG) as a new tool for the study of normal and abnormal fetal heart rate and rhythm.

Perioperative Depression and Postoperative Arrhythmia in Elective Coronary Bypass Graft Surgery

Postoperative arrhythmias (heart irregularities) are one of the most common complications after cardiac surgery and are associated with increased morbidity and mortality. Preoperative depression may be an important co-factor in the generation of postoperative arrhythmias due to sympathetic hyperactivity evident in patients with depression. Objectives: To determine the effect of preoperative depression on postoperative arrhythmia in patients undergoing elective coronary artery ...

Diagnostic Investigation of Sudden Cardiac Event Risk

Heart failure (HF) affects 5 million Americans, with 500,000 new cases diagnosed and 250,000 deaths each year. The two major causes of morbidity and mortality in HF are pump failure and sudden, lethal ventricular arrhythmias, the latter of which accounts for 40-50% of HF deaths. Arrhythmias may be precipitated by a complex interaction of genetic and environmental factors. Establishing increased risk for arrhythmias before a severe life-threatening event is critically importa...
