High blood pressure and cardiac arrhythmia two dangerous companions
High blood pressure (hypertension) is by far the biggest risk factor when it comes to the development of cardiac arrhythmias. There is a direct correlation between the blood pressure level and the probability of being afflicted by atrial fibrillation. The permanent pressure on the heart causes the myocardium to enlarge (hypertrophy). Due to this, the cardiac tissue no longer receives an optimal supply of blood and heart muscle cells begin to die off imperceptibly. These cells are then replaced by connective tissue cells, which do not allow for adequate blood flow and therefore cause the normal “electrical system“ of the heart to go haywire, thus promoting cardiac arrhythmias.
