1st Degree Atrioventricular (AV) Block, 1st Degree Heart Block
Definition
1st degree atrioventricular (AV) block, also known as 1st degree heart block, is a mild form of arrhythmia. The heartbeat is irregular or abnormal due to a delay in the electrical signals passing from the atria to the ventricles through the atrioventricular node. This condition often does not cause any symptoms and may be detected incidentally during an electrocardiogram (ECG).

Cardiovascular Medicine
At Yale Medicine, our cardiovascular physicians specialize in all types of heart conditions. Our expert teams focus on heart-related health issues, such as heart disease genetics, heart rhythm problems, heart failure, heart and blood vessel conditions, and heart transplants. Our cardiologists do more than just see patients; they also conduct research to learn more about the complexities of various heart diseases and investigate better ways to treat them. Through their work in five research centers at Yale our cardiologists participate in major research initiatives focused on all aspects of heart health. Our research teams are comprised of experts from all over the world—eight different countries and four continents, to be exact! Specialized care is offered in the following areas: Adult congenital heart disease Arrhythmia Cardiac imaging Cardiomyopathy and congestive heart failure Coronary heart disease General cardiology (including stress tests and holter monitoring) Peripheral vascular heart disease Vascular heart diseaseAdult Congenital Heart Program
As our pediatric congenital heart disease patients move from childhood into adulthood, our program is there every step of the way to make sure they receive continuous, comprehensive care for even the most complex heart disease. Our multidisciplinary integrated program was the first in the state dedicated to the care of adult patients with complex congenital heart disease, and encompasses the full spectrum of care, including imaging, exercise testing, and surgical as well as less-invasive catheterization therapies. Our patients can expect to receive detailed information about their underlying congenital heart defect, its management, and the implications on their future heart function. Patients in the program are assured of the careful transition of care from their childhood diagnosis into adulthood, and appropriate wrap-around care for adults who are new to the program. Commonly encountered problems related to adult congenital heart disease (ACHD) include the following: Unrepaired congenital defects Complications associated with early surgical repair Heart failure Heart rhythm problems, including pacemakers and defibrillators Pregnancy issues Our expert, board-certified cardiac physicians and surgeons treat these, among other heart conditions: Atrial septal defect (ASD) Ventricular septal defect (VSD) Atrioventricular canal defect Bicuspid aortic valve Pulmonary stenosis Coarctation of the aorta Ebstein's anomaly Transposition of the great arteries, including those who have had a Mustard or Senning operation or arterial switch operation Congenitally corrected transposition of the great arteries Tetralogy of Fallot Complex single ventricle patients, including those who had a Fontan operation Cyanotic heart disease Patients who had a Ross operation as a child Congenital coronary anomalies, including ALCAPA (anomalous left coronary artery from the pulmonary artery) Instead of delaying treatment for complex congenital heart disease, our state-of-the-art imaging, including echocardiograms (ultrasound) and MRI, allows for early diagnosis, before symptoms may interfere with a patient’s life. Our program also works closely with Yale's maternal-fetal medicine team to care for women with congenital heart disease before and after they give birth. Yale’s world-class congenital cardiac catheterization lab provides access to the latest advances in transcatheter valve placement, treatment of atrial septal defects, and all forms of congenital heart disease. We provide comprehensive electrophysiology services, including management of arrhythmias and placement of pacemakers and defibrillators.Electrophysiology & Cardiac Arrhythmia Program
Our highly skilled and experienced team specializes in electrophysiology, or the diagnosis and treatment of heart-rhythm abnormalities, also known as arrhythmias. We treat complex arrhythmias and structural heart disease at Yale New Haven Hospital and through several outpatient office locations. At Yale New Haven Hospital, our physicians operate Connecticut’s largest and most comprehensive program for ventricular tachycardia ablation, a procedure that eliminates the heart tissue that causes arrhythmia. Our Complex Ablation Program offers epicardial ablation to treat ventricular tachycardia and atrial fibrillation that originates from the outer surface of the heart. Our operating suites are equipped with cutting-edge technology, including three-dimensional mapping systems, intracardiac ultrasound, and robotics. We offer a full range of device therapies, including pacemakers, defibrillators, and cardiac resynchronization therapy (CRT). We routinely monitor implantable devices using remote technology to ensure patients’ safety, wherever they are. We also offer a clinic in which doctors from electrophysiology and geriatrics work together to manage patients with recurrent falls and syncope, or fainting caused by low blood pressure. Additionally, Yale New Haven Hospital runs the only Atrial Fibrillation Support Group in the state. The group is for all patients and their families and aims to help individuals and their loved ones cope with the psychological and emotional burdens of their disease. For patients at Yale New Haven Hospital, an advanced nurse practitioner dedicated to arrhythmia management is ready to assist, working closely with physicians to ensure a seamless inpatient to outpatient transition.
