2. Atrial fibrillation - Wikipedia

   en.wikipedia.org/wiki/Atrial_fibrillation

   Atrial fibrillation is associated with an increased risk of heart failure, dementia, and stroke. [3] [12] It is a type of supraventricular tachycardia. [14] Atrial fibrillation frequently results from bursts of tachycardia that originate in muscle bundles extending from the atrium to the pulmonary veins. [15]

   Digoxin: Helps slow the heart rate by blocking the number of electrical impulses that pass through the AV node into the lower heart chambers (ventricles). Electrocardioversion: A procedure in which electric currents are used to reset the heart's rhythm back to regular pattern. [3]

4. Cardiovascular examination - Wikipedia

   en.wikipedia.org/wiki/Cardiovascular_examination

   The cardiovascular examination is a portion of the physical examination that involves evaluation of the cardiovascular system. The exact contents of the examination will vary depending on the presenting complaint but a complete examination will involve the heart (cardiac examination), lungs (pulmonary examination), belly (abdominal examination) and the blood vessels (peripheral vascular ...

   Certain medications that help control the heart rate might be given, or medications that reduce the likelihood of blood clot formation and therefore prevent stroke. Also, patients might receive an implantable cardiac pacemaker, which, by constantly pacing the atrium, can reduce the chance of an AF episode.

6. Atrioventricular node - Wikipedia

   en.wikipedia.org/wiki/Atrioventricular_node

   This is the property of the AV node that prevents rapid conduction to the ventricle in cases of rapid atrial rhythms, such as atrial fibrillation or atrial flutter. The AV node's normal intrinsic firing rate without stimulation (such as that from the SA node) is 40–60 times/minute. [13]

7. Pulse - Wikipedia

   en.wikipedia.org/wiki/Pulse

   Measuring the pulse rate is therefore a convenient way to estimate the heart rate. [7] Pulse deficit is a condition in which a person has a difference between their pulse rate and heart rate. It can be observed by simultaneous palpation at the radial artery and auscultation using a stethoscope at the PMI, near the heart apex, for example ...
