  2. Third-degree atrioventricular block - Wikipedia

    en.wikipedia.org/wiki/Third-degree_atrio...

    The cause of congenital third-degree heart block in many patients is unknown. Studies suggest that the prevalence of congenital third-degree heart block is between 1 in 15,000 and 1 in 22,000 live births. [citation needed] Hyperkalemia in those with previous cardiac disease [8] and Lyme disease can also result in third-degree heart block. [9]

  3. Lev's disease - Wikipedia

    en.wikipedia.org/wiki/Lev's_disease

    Lev's disease, also known as Lenegre disease, is an idiopathic disease that can result in a complete heart block, or an extremely slowed heart rate, in patients with this condition. It is thought that for certain patients, this impairment of heart's electrical conduction system is due to fibrosis and calcification of conduction cells.

  4. Coronary ischemia - Wikipedia

    en.wikipedia.org/wiki/Coronary_ischemia

    Reduced blood flow to the heart associated with coronary ischemia can result in inadequate oxygen supply to the heart muscle. [6] When oxygen supply to the heart is unable to keep up with oxygen demand from the muscle, the result is the characteristic symptoms of coronary ischemia, the most common of which is chest pain. [6]

  7. Heart block - Wikipedia

    en.wikipedia.org/wiki/Heart_block

    Despite the severe-sounding name, heart block may cause no symptoms at all in some cases, or occasional missed heartbeats in other cases (which can cause light-headedness, syncope (fainting), and palpitations), or may require the implantation of an artificial pacemaker, depending upon exactly where in the heart conduction is being impaired and ...

  8. Ischemic cardiomyopathy - Wikipedia

    en.wikipedia.org/wiki/Ischemic_cardiomyopathy

    Ischemic cardiomyopathy is a type of cardiomyopathy caused by a narrowing of the coronary arteries which supply blood to the heart. [4] Typically, patients with ischemic cardiomyopathy have a history of acute myocardial infarction, [5] however, it may occur in patients with coronary artery disease, but without a past history of acute myocardial infarction.

  9. Second-degree atrioventricular block - Wikipedia

    en.wikipedia.org/wiki/Second-degree_atrio...

    Second-degree atrioventricular block (AV block) is a disease of the electrical conduction system of the heart. It is a conduction block between the atria and ventricles. The presence of second-degree AV block is diagnosed when one or more (but not all) of the atrial impulses fail to conduct to the ventricles due to impaired conduction.
