17 terms — criteria, diagrams, and real ECG strips
Brugada syndromeBrugada syndrome is an inherited channelopathy associated with an increased risk of life-threatening ventricular arrhythmias in a structurally normal heart.
Brugada type 1 patternBrugada type 1 pattern is a coved ST-segment elevation in the right precordial leads transitioning into a negative T wave without an isoelectric baseline between them.
Brugada type 2 patternBrugada type 2 pattern is an ECG finding in the right precordial leads characterized by a saddleback ST-segment elevation and a positive or biphasic T wave.
Long QT syndromeLong QT syndrome (LQTS) is a congenital or acquired disorder of ventricular repolarization featuring pathological prolongation of the QT interval and a risk of polymorphic VT...
Romano–Ward syndromeRomano–Ward syndrome is a congenital long QT syndrome (LQTS) with an autosomal dominant inheritance pattern and normal hearing.
Jervell and Lange-Nielsen syndromeJervell and Lange-Nielsen syndrome is a rare autosomal recessive channelopathy combining congenital long QT syndrome with congenital sensorineural hearing loss.
Short QT syndromeShort QT syndrome (SQTS) is an inherited channelopathy characterized by a shortened QT interval and an increased risk of ventricular tachyarrhythmias and sudden cardiac...
Catecholaminergic polymorphic VTCatecholaminergic polymorphic ventricular tachycardia (CPVT) is an inherited channelopathy characterized by...
Early repolarization syndromeEarly repolarization pattern (ERP) is an ECG finding characterized by elevation of the J point and ST segment in the inferior and/or lateral leads, unrelated to...
Arrhythmogenic right ventricular cardiomyopathyArrhythmogenic right ventricular cardiomyopathy (ARVC, engl.
Epsilon waveAn epsilon wave is a small, low-amplitude deflection or notch occurring immediately after the end of the QRS complex, prior to the onset of the ST segment.
Hypertrophic cardiomyopathyHypertrophic cardiomyopathy (HCM) is a myocardial disease, most commonly caused by inherited variants in sarcomeric protein genes, characterized by...
Apical hypertrophic cardiomyopathyApical hypertrophic cardiomyopathy (apical HCM, Yamaguchi syndrome) is a variant of hypertrophic cardiomyopathy with myocardial thickening predominantly affecting the left ventricular apex.
Dilated cardiomyopathyDilated cardiomyopathy (DCM) is a phenotype characterized by dilation and systolic dysfunction of predominantly the left ventricle or both ventricles, not explained by...
Restrictive cardiomyopathyRestrictive cardiomyopathy is a myocardial disease characterized by impaired ventricular diastolic filling due to increased wall stiffness in the presence of generally preserved systolic...
Takotsubo cardiomyopathyTakotsubo cardiomyopathy is a transient left ventricular myocardial dysfunction, typically featuring apical ballooning, triggered by severe...
Myocarditis on ECGMyocarditis is an inflammatory disease of the myocardium, most commonly of viral or autoimmune origin.
