491 Possible Causes for AV Block Mobitz II, Focal Atrophy of Choroid, Prolonged PR Interval

  • AV Block Mobitz I

    Second-degree AV block, Mobitz II.[aibolita.com] PR interval gradually prolongs and the 5th beat from the left is not conducted. The cycle restarts and PR interval gradually prolongs again. Dr.[metealpaslan.com] There are features of both Mobitz I (AV Wenckebach) and Mobitz II on this tracing. In favor of Mobitz II is the low conduction ratio and high grade of AV block.[ahcmedia.com]

Shortened ST segment 68. A. Prominent U waves B. Prolonged PR interval C. Depressed ST segment D. Widened QRS complexes 69. A. Alcoholism B.[proprofs.com] The PR interval is prolonged. Occasionally sinoatrial (SA) block, second- or third-degree atrioventricular (AV) block may develop.[ecgwaves.com]

    Pronounced PR interval prolongation. The effect of this PR interval prolongation on AV dyssynchrony is demonstrated in this ECG image.[emedicine.medscape.com] AV dyssynchrony resulting from severe PR interval prolongation in the setting of sinus rhythm.[emedicine.medscape.com] In this ECG, the PR interval is prolonged to the point that the P wave occurs coincident with the peak of the T wave.[emedicine.medscape.com]

    Almost any type of arrhythmia can occur in digoxin toxicity except Mobitz type II second degree AV block and atrial fibrillation with a fast ventricular rate.[cardiophile.org] The earliest signs of toxicity in the newborn are undue slowing of the pulse rate (bradycardia), sinoatrial arrest and prolongation of the PR Interval (A Collins Abrams, 2006[rn.com] ECG Changes The use of therapeutic doses of LANOXIN may cause prolongation of the PR interval and depression of the ST segment on the electrocardiogram.[rxlist.com]
