Heart rhythm disturbances
Heart rhythm disturbances or arrhythmias is a condition affecting electrical responses in the heart. When this happens, it can cause irregular heartbeats; too fast or too slow. The patient may feel like there is an unusual rhythm and is skipping a beat. Cardiac arrhythmia means improper electrical conduction.
Foreign invaders may enter the body  and travel to the heart muscle, causing infection. Irritants such as bacteria, virus, parasite, or a chemical can cause infections. Effects include inflammation and damage to some parts of the heart like the inner lining, outer membrane, and valves. If left untreated, this condition can cause serious health complications or may lead to death.
