Supraventricular tachycardia (SVT) is a heart rhythm disorder characterized by a rapid and irregular heartbeat originating above the heart's ventricles. This condition causes the heart to beat faster than normal, typically with a rate exceeding 100 beats per minute. SVT can occur suddenly and may be triggered by various factors, including stress, caffeine, or certain medications. Symptoms can vary but often include palpitations, rapid heartbeat, chest discomfort, dizziness, and sometimes fainting. In many cases, SVT is not life-threatening, but it can be distressing and uncomfortable. Treatment options for SVT aim to restore a normal heart rhythm and may include techniques like vagal maneuvers (such as bearing down or applying ice to the face), medications, or minimally invasive procedures like catheter ablation to correct the abnormal electrical pathways in the heart. The choice of treatment depends on the specific circumstances and severity of the condition. People with SVT should work closely with a healthcare provider to develop a management plan tailored to their needs and to address any potential underlying causes or risk factors.
In this comprehensive article, we will delve into SVT, exploring its types, causes, risk factors, symptoms, prevention strategies, diagnosis and evaluation, treatment and management, and when it's crucial to seek medical advice.
Atrioventricular canal defect (AV canal defect), also known as atrioventricular septal defect (AVSD), is a congenital heart defect that affects the structure of the heart's atria and ventricles as well as the valves between them. In AV canal defect, there is an abnormal hole or opening in the center of the heart, which results in the incomplete separation of the heart's upper chambers (atria) and lower chambers (ventricles). This condition can lead to the mixing of oxygenated and deoxygenated blood, causing the heart to work harder to pump oxygen-rich blood to the body. AV canal defect often occurs in association with other congenital abnormalities, and its severity can vary. Infants born with AV canal defects may exhibit symptoms such as rapid breathing, poor feeding, failure to thrive, and blue-tinged skin. Surgical intervention is typically required to repair the defect and improve the heart's function. Without treatment, AV canal defects can lead to serious complications, including heart failure and pulmonary hypertension. Early diagnosis, close monitoring, and timely medical intervention are crucial for managing this congenital heart condition and optimizing outcomes.
In this comprehensive article, we will delve into AV Canal Defect, exploring its types, causes, risk factors, symptoms, prevention strategies, diagnosis and evaluation, treatment and management, and when it's crucial to seek medical advice.
Atrioventricular Nodal Reentry Tachycardia (AVNRT) is a common type of supraventricular tachycardia (SVT) that affects the heart's electrical system, leading to episodes of rapid and irregular heartbeats. AVNRT occurs when there is an abnormal electrical pathway within the atrioventricular (AV) node, causing the heart to beat faster than usual. In this comprehensive article, we will delve into AVNRT, exploring its types, causes, risk factors, symptoms, prevention strategies, diagnosis and evaluation, treatment and management, and when it's crucial to seek medical advice.
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder that affects both children and adults, but it is often first diagnosed in childhood. It can significantly impact a child's daily life, including their performance in school, relationships with peers and family, and overall well-being. In this comprehensive article, we will delve into ADHD in children, exploring its types, causes, risk factors, symptoms, prevention strategies, diagnosis and evaluation, treatment and management, and when it's crucial to seek medical advice.
Atypical hyperplasia of the breast is a condition that involves abnormal cell growth in the breast tissue. While it is not cancer, it is considered a high-risk factor for the development of breast cancer. Understanding this condition, its types, causes, risk factors, symptoms, prevention strategies, diagnosis and evaluation, treatment and management, and knowing when to seek medical attention is crucial. In this comprehensive article, we will explore atypical hyperplasia of the breast in detail.
Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder that affects individuals differently. It is characterized by a range of symptoms, including challenges in communication, social interaction, and repetitive behaviors. Understanding ASD, its types, causes, risk factors, symptoms, prevention strategies, diagnosis and evaluation, treatment and management, and knowing when to seek medical advice is crucial for individuals and families dealing with this condition. In this comprehensive article, we will explore autism spectrum disorder in detail.
Autoimmune hepatitis (AIH) is a rare but serious autoimmune disorder that affects the liver. In this comprehensive article, we will delve into the various aspects of autoimmune hepatitis, including its types, causes, risk factors, symptoms, prevention, diagnosis, treatment, and when to seek medical attention.
Autoimmune pancreatitis (AIP) is a rare and often misunderstood condition that affects the pancreas. In this comprehensive article, we will explore all facets of autoimmune pancreatitis, including its types, causes, risk factors, symptoms, prevention, diagnosis, treatment, and when to seek medical assistance.
The autonomic nervous system (ANS) is responsible for regulating involuntary bodily functions like heart rate, blood pressure, digestion, and sweating. Autonomic neuropathy is a condition that disrupts this vital system, leading to a wide range of symptoms and complications. In this comprehensive article, we'll delve into autonomic neuropathy, including its types, causes, risk factors, symptoms, prevention, diagnosis, treatment, and when to seek medical attention.
Avascular necrosis (AVN), also known as osteonecrosis, is a debilitating condition that affects the bones, primarily the joints. This condition occurs when there is a lack of blood supply to a specific bone, leading to bone tissue death. In this comprehensive article, we will delve into avascular necrosis, covering its types, causes, risk factors, symptoms, prevention, diagnosis, treatment, and when to seek medical attention.
Auditory Processing Disorder (APD), also known as central auditory processing disorder (CAPD), is a type of hearing impairment that affects how the brain processes auditory information. Unlike traditional hearing loss caused by ear damage, APD originates from issues within the central nervous system. Let’s explore this condition in detail.
Atelectasis, pronounced “at-uh-LEK-tuh-sis,” refers to the partial or complete collapse of a lung or a specific lobe within the lung. This condition occurs when the tiny air sacs (alveoli) fail to properly inflate, leading to impaired gas exchange and reduced oxygen levels in the bloodstream.
Azoospermia is a medical condition characterized by the absence of sperm in the ejaculate, which can result in male infertility. It affects approximately 1% of the male population and is a contributing factor in 10-15% of male infertility cases. The condition can be categorized into different types based on its underlying causes, including pretesticular, testicular, and post-testicular azoospermia. Understanding the types, causes, risk factors, and treatment options for azoospermia is crucial for effective diagnosis and management.
