5.5 Right Ventricular Hypertrophy Right Ventricular Hypertrophy Mechanism: Hypertrophy of the right ventricular musculature as a consequence of systolic or diastolic overload ECG characteristics: Often right axis P pulmonale (P…
5.3 Mitral Valve Prolapse Syndrome Mitral Valve Prolapse Syndrome Definition: Symptoms that are attributed to mitral valve anomaly or to neuroendocrine dysfunction, which cannot be solely explained by mitral valve…
2.3 Depolarization of the Atria (P Wave) The first electrical activity conspicuous in sinus rhythm is depolarization of the atria; a P wave occurs. The beginning of the P wave…
2.4 Conduction of the AV Node Following successful atrial depolarization, the electrical impulse is further conducted via the AV node, the bundle of His and the bundle branches. The individual…
1.9 The Isthmus Region Size/form: Variable expansion of the area Location: Between the tricuspid valve, inferior vena cava, and the opening of the coronary sinus
2.1 Basic Concepts The conduction diagram represents a simplified projection of impulse conduction at the various anatomical levels of the heart on a time axis. Using typical ECG recordings a…
1.8 The Fast Pathway Region Size/form: Variable expansion of the fibers Location: In the region of the intraatrial septum anterosuperior to the KOCH triangle
1.7 The Slow Pathway Region Size/form: Variable expansion of the fibers Location: Between the opening of the coronary sinus and the compact AV node (posteroinferior to the compact AV node)
1.4 The Compact AV Node Size/form: ca. 1×3×5mm Location: Base of the right atrium at the point of the so-called Koch triangle (between the tricuspid annulus and the eustachian valve),…
1.6 The Bundle Branches Right bundle branch: Extension of the bundle of His coursing along the right aspect of interventricular septum
