Ductal-dependent congenital heart disease (DDCHD) refers to heart defects that require the ductus arteriosus to remain open for sufficient blood flow, as its closure can lead to severe hypoxia and cardiovascular collapse. Common types include …
Congenital heart disease (CHD) encompasses various heart defects present at birth, affecting nearly 1% of live births globally, with about 40,000 infants in the U.S. diagnosed each year. Acyanotic heart disease, which constitutes around 75% of CHD …
The article discusses the various types of congenital heart defects (CHDs), categorizing them into obstructive defects, septal defects, cyanotic defects, and complex defects. Obstructive defects, like aortic and pulmonary stenosis, block blood flow. …
The article provides a comprehensive overview of congenital heart defects (CHDs), which are structural heart abnormalities present at birth, affecting approximately 1 in 100 babies in the U.S. It highlights various types of CHDs, including Atrial …
Postpartum cardiomyopathy (PPCM) is a rare and serious heart condition that can develop towards the end of pregnancy or within months after childbirth, characterized by weakened heart muscle, enlarged heart, and reduced ejection fraction. Symptoms …
A pacemaker is a small device implanted in the chest to regulate heartbeats, primarily for patients with bradycardia or other arrhythmias. It sends electrical impulses to maintain a stable heart rhythm, significantly improving the quality of life and …
The article “Understanding Arrhythmias: What You Need to Know” discusses arrhythmias, which are irregular heart rhythms that can be too fast (tachycardia), too slow (bradycardia), or erratic. These conditions can compromise the …
The article provides a comprehensive overview of atrial fibrillation (AFib) and supraventricular tachycardia (SVT), highlighting their key differences. AFib is marked by rapid, irregular heart rhythms from the atria, potentially leading to serious …
The article “Understanding Arrhythmia: Types, Causes, and Symptoms” provides a comprehensive overview of arrhythmia, a disorder characterized by irregular heart rhythms, which can be categorized into tachycardia (fast heart rate) and …
Atrioventricular nodal reentrant tachycardia (AVNRT) is the most common type of supraventricular tachycardia (SVT), marked by rapid heart rates of 140 to 280 beats per minute due to an extra electrical pathway in the heart. It occurs when a premature …
Nonsustained ventricular tachycardia (NSVT) is a type of arrhythmia marked by episodes of rapid heart rates originating from the ventricles, lasting less than 30 seconds and often resolving spontaneously. While it may not significantly affect life …
Arrhythmia is a condition marked by irregular heartbeats, which can occur as tachycardia (rapid heart rate), bradycardia (slow heart rate), or irregular rhythms. It results from malfunctioning electrical signals in the heart, potentially leading to …
Ventricular tachycardia (VT) is a life-threatening arrhythmia where the heart’s ventricles beat rapidly, often over 100 beats per minute, disrupting normal blood flow. VT can be sustained (lasting over 30 seconds) or nonsustained (lasting less …
Cardiac cough is a persistent, wet cough resulting from fluid accumulation in the lungs due to congestive heart failure (CHF). This occurs when the heart fails to pump blood effectively, causing fluid backup and pulmonary congestion. Symptoms of …
Ventricular tachycardia (VT) is a rapid heartbeat originating from the heart’s ventricles, typically exceeding 100 beats per minute due to misfiring electrical signals. It can be classified as monomorphic (consistent electrical impulses) or …
A junctional escape rhythm is a cardiac arrhythmia that occurs when the sinoatrial (SA) node fails to initiate a heartbeat, causing the heart to rely on backup pacemakers near the atrioventricular (AV) node, leading to a heart rate of 40 to 60 beats …
Atrial tachycardia is a type of arrhythmia where the atria of the heart beat faster than normal, typically between 100 to 250 beats per minute. This condition is part of supraventricular tachycardia (SVT) and is caused by faulty electrical signals in …
The article discusses the serious complications associated with arrhythmia, characterized by irregular heartbeats that can lead to inadequate blood circulation and weaken the heart muscle over time. Complications such as atrial fibrillation (AFib) …
Pulmonary atresia (PA) is a serious congenital heart defect characterized by the improper formation of the pulmonary valve, obstructing blood flow from the right ventricle to the pulmonary artery. This condition affects approximately 1 in 10,000 live …
Polymorphic ventricular tachycardia (PVT) is a serious heart arrhythmia characterized by irregular heart rhythms originating from the ventricles, displaying multiple shapes on electrocardiograms. It can lead to severe complications like syncope, …
Wide complex tachycardia (WCT) refers to a condition characterized by a heart rate exceeding 100 bpm and an elongated QRS complex on an electrocardiogram (EKG), indicating disruptions in the heart’s electrical conduction. WCT is categorized …
Ectopic Atrial Tachycardia (EAT) is a pediatric arrhythmia marked by rapid heartbeats originating from an ectopic focus in the atria, which can significantly affect children’s health. Symptoms may include heart palpitations, dizziness, fatigue, …
