14 Possible Causes for 1 atrioventricular block, Giddiness and Lightheadedness

  • Orthostatic Hypotension

    We describe the case of an 81-year-old male patient with long PR interval and episodes of 2:1 atrioventricular block, in whom the implantation of a dual chamber pacemaker[ncbi.nlm.nih.gov]

  • Bradyarrhythmia

    Pathology A fetal bradyarrhythmia can fall into several types which include fetal partial atrioventricular block (PAVB) fetal complete atrioventricular block (CAVB) : considered[radiopaedia.org] Asymptomatic third- or second-degree (Mobitz I or II) atrioventricular block IIa C 2.

  • Vasovagal Syncope

    Abstract A 21 year old man presented with multiple, recurrent episodes of complete atrioventricular (AV) block associated with swallowing.[ncbi.nlm.nih.gov] Author information 1 Asahikawa Medical College, First Department of Internal Medicine, Midorigaoka Higashi 2-1-1-1, Asahikawa, Hokkaido, 078 8510, Japan.[ncbi.nlm.nih.gov]

  • Anaphylaxis

    Furthermore, in healthy individuals, histamine may induce arrhythmias and atrioventricular conduction blocks.[ncbi.nlm.nih.gov] These effects are due mainly to the activation of H 1 receptors expressed on vascular smooth muscle.[ncbi.nlm.nih.gov]

  • Hypokalemia

    Severe hypokalemia can also cause a variety of tachyarrhythmias, including ventricular tachycardia/fibrillation and rarely atrioventricular block. 3 Treatment of hypokalemia[doi.org] […] involves parenteral and oral potassium supplementation, as well as identification and treatment of the underlying cause. 1 References 1.[doi.org] […] masking the smaller preceding T waves becomes apparent on the ECG. 1,2 A pseudo-prolonged QT interval may be seen, which is actually the QU interval with an absent T wave. 1[doi.org]

  • Electrolytes Abnormal

    Refer to Figure 1. The PR interval is prolonged. Occasionally sinoatrial (SA) block, second- or third-degree atrioventricular (AV) block may develop.[ecgwaves.com]

  • Sick Sinus Syndrome
