- Long QT syndrome

Aging has been known to cause various medical complications, and cardiac arrhythmia is one of them. The scarring within the cardiac muscle may lead to sinus syndrome, heart blocks, or atrial fibrillation.
This is one of the reasons why the elderly often require pacemakers.
Various immune system disorders such as kidney disease, diabetes, dehydration, and the like can cause heart arrhythmias. Since electrolytes help conduct the electrical impulses in the heart, having a deficit can affect your heart’s rhythm and can lead to arrhythmia development.
The more common type of metabolic disorders that cause heart arrhythmia are:
- Hypokalemia (low potassium levels)
- Hyperkalemia (high potassium levels)
- Hypomagnesemia (low magnesium levels)
- Hypocalcemia (low calcium levels)
- Acidosis (blood too acidic)
- Alkalosis (blood too alkaline)
Another common cause of heart arrhythmia would be anesthesia. Patients who are placed under anesthesia may experience fluctuations in blood pressures, electrolyte and metabolic disorders, and cardiovascular damage.
People who experience cardiac trauma from chest wounds may experience muffled heart tones, murmurs, or arrhythmias.
