Electrophysiology Conditions

Atrial fibrillation (AF) is a heart condition characterized by an irregular and rapid heartbeat that hampers blood supply to the body. In atrial fibrillation, the upper chambers (atria) and the lower chambers (ventricles) of the heart lack coordination, causing a rapid and irregular heart rhythm. People with atrial fibrillation may experience palpitations, shortness of breath, and fatigue or lack of energy.

Atrial flutter is a type of abnormal heart rhythm in which the atria (the upper chambers of the heart) beat too quickly. The heart's natural pacemaker, located in the sinoatrial (SA) node, sends electrical impulses at a rate of about 60-100 beats per minute. In atrial flutter, the atria beat at a rate of about 250-350 beats per minute. Because of this rapid heart rate, the atria do not have enough time to fill with blood before contracting, which can lead to symptoms such as palpitations, lightheadedness, and shortness of breath.

Brady arrhythmia is a medical condition characterized by an abnormally slow heart rate. It can be caused by a variety of factors, including age-related changes, certain medications, and underlying health conditions such as coronary artery disease or thyroid disorders. Symptoms of brady arrhythmia include fatigue, dizziness, shortness of breath and fainting. Treatment depends on the underlying cause and may include medications to regulate the heart rate or electrical treatments such as pacing or ablation.

Electrical signals generated in the heart cause it to contract and beat in order to pump blood throughout the body. An electrical conduction system helps transmit these signals throughout the heart chambers, atria and ventricles. When the heart beats slowly or irregularly as a result of electrical signal interruption, it is called heart block and affects the flow of blood from the heart.

Sick sinus syndrome is a heart rhythm disorder that occurs when the sinoatrial node, which is responsible for controlling the heartbeat, fails to function properly. It can cause a wide range of symptoms, including fatigue, dizziness, chest pain, and fainting. Treatment options for sick sinus syndrome include medications and pacemaker implantation. With early diagnosis and proper treatment, patients with this condition can lead a healthy life.

Supraventricular tachycardia (SVT) is a type of cardiac arrhythmia characterized by a rapid heart rate caused by abnormal electrical signals in the upper chambers of the heart. It is a common condition that can cause palpitations, shortness of breath, chest pain, and dizziness. SVT can be treated with medications or invasive procedures depending on the severity and underlying cause.

Ventricular arrhythmias are a type of heart rhythm disorder in which the lower chambers of the heart, known as ventricles, beat irregularly or too fast. This can lead to serious complications such as stroke, cardiac arrest, and even death. Treatment for ventricular arrhythmias may involve medications, electrical cardioversion, or implantable devices such as pacemakers or defibrillators.

Ventricular fibrillation (VF) is a life-threatening arrhythmia that occurs when the heart's ventricles quiver instead of contracting normally. This can lead to a lack of blood flow to the brain, which can cause death within minutes if not treated quickly. VF can be treated with defibrillation, which can restore normal electrical activity in the heart and allow it to start pumping blood again.

Ventricular tachycardia is a condition characterized by an abnormally fast heart rate originating from the ventricles of the heart. It can cause a wide range of symptoms and can be life-threatening if not treated appropriately. Ventricular tachycardia can be caused by many different underlying conditions, including coronary artery disease, cardiomyopathy, and congenital heart defects. Treatment options vary depending on the cause and severity of the condition, but may include medications, catheter ablation, or implantation of a pacemaker or defibrillator.

Syncope, also known as fainting or passing out, is the temporary loss of consciousness caused by insufficient blood flow to the brain. This often occurs due to low blood pressure, changes in heart rhythm, and pooling of blood in regions of the body.

Tachycardia is an abnormal increase in the heart rate. Postural tachycardia syndrome is an increase in the heart rate when there is a change in posture, i.e. when you stand up from a lying position. Postural tachycardia syndrome belongs to a group of disorders where the main symptom is intolerance to standing up from a lying or sitting position.
