Arrhythmias and Conduction conditions
Atrial Fibrillation (AFib)Atrial fibrillation (AFib) is an irregular, often rapid heart rhythm caused by disorganized atrial electrical activity, increasing stroke risk and requiring careful management.Atrial FlutterAtrial Flutter is a cardiac arrhythmia characterized by rapid, regular atrial contractions caused by a reentrant circuit in the right atrium, often leading to palpitations and risk of stroke.Brugada SyndromeBrugada Syndrome is a genetic disorder causing abnormal heart rhythms and increased risk of sudden cardiac death, identified by characteristic ECG patterns.Bundle Branch Block (BBB)Bundle Branch Block (BBB) is a cardiac conduction abnormality where electrical impulses are delayed or blocked in the heart's bundle branches, causing altered ventricular activation.Congenital Long QT SyndromeCongenital Long QT Syndrome is a genetic disorder causing prolonged cardiac repolarization, leading to arrhythmias and risk of sudden cardiac death.First-Degree AV BlockFirst-Degree AV Block is a cardiac conduction delay characterized by prolonged PR interval on ECG without missed beats, often asymptomatic and caused by AV nodal conduction slowing.Mobitz Type I (Wenckebach) AV BlockMobitz Type I (Wenckebach) AV Block is a second-degree heart block characterized by progressive PR interval prolongation until a dropped beat occurs, often causing irregular rhythm.Mobitz Type II AV BlockMobitz Type II AV Block is a second-degree heart block with sudden dropped QRS complexes due to conduction failure below the AV node, often requiring pacing.Multifocal Atrial Tachycardia (MAT)Multifocal Atrial Tachycardia (MAT) is an irregular atrial rhythm with multiple ectopic foci causing variable P wave morphologies and rapid heart rate, often linked to lung disease.Paroxysmal Supraventricular Tachycardia (PSVT)Paroxysmal supraventricular tachycardia (PSVT) causes sudden rapid heartbeats from reentrant circuits above the ventricles, often triggered by AV nodal pathways.Premature Atrial Contraction (PAC)Premature Atrial Contraction (PAC) involves early heartbeats originating in the atria, causing irregular rhythms often detected on ECG as premature P waves.Premature Ventricular Contraction (PVC)Premature Ventricular Contraction (PVC) is an early heartbeat originating in the ventricles, causing irregular heart rhythm and palpitations detectable on ECG.Sick Sinus Syndrome (SSS)Sick Sinus Syndrome (SSS) is a group of heart rhythm disorders caused by malfunction of the sinus node, leading to bradycardia, pauses, or alternating tachyarrhythmias.Sudden Cardiac DeathSudden Cardiac Death is an unexpected death caused by abrupt loss of heart function, often due to arrhythmias or underlying coronary artery disease.Third-Degree (Complete) AV BlockThird-degree (complete) AV block is a cardiac conduction disorder where atrial impulses fail to reach ventricles, causing independent atrial and ventricular rhythms.Torsades de PointesTorsades de Pointes is a polymorphic ventricular tachycardia linked to prolonged QT interval, often triggered by electrolyte imbalances or medications.Ventricular Fibrillation (VF)Ventricular fibrillation (VF) is a life-threatening arrhythmia causing chaotic ventricular contractions and sudden cardiac arrest due to electrical disorganization.Ventricular Tachycardia (VT)Ventricular Tachycardia (VT) is a rapid heart rhythm originating from the ventricles, often linked to ischemic heart disease and risk of sudden cardiac arrest.Wolff-Parkinson-White SyndromeWolff-Parkinson-White Syndrome is a cardiac condition caused by an accessory pathway leading to episodes of tachycardia and characteristic delta waves on ECG.
