kardioverters

A cardioverter is a medical device used to treat certain types of irregular heart rhythms, known as arrhythmias. These devices deliver a controlled electrical shock to the heart, aiming to restore a normal heart rhythm. Cardioverters are typically used in emergency situations when a rapid and irregular heartbeat poses a significant risk to the patient's health. The electrical shock is synchronized with the heart's electrical activity, specifically the R-wave, to minimize the risk of inducing a more dangerous arrhythmia like ventricular fibrillation. This synchronization is a key feature that distinguishes it from a defibrillator, which delivers an unsynchronized shock.

The procedure is usually performed by trained medical professionals in a hospital setting, often in an emergency room or intensive care unit. Before the procedure, the patient may be given a sedative to reduce discomfort and anxiety. Electrodes are placed on the patient's chest to deliver the electrical current. The energy level of the shock is determined by the specific arrhythmia and the patient's condition. After the shock is delivered, the patient's heart rhythm is monitored to assess the effectiveness of the cardioversion. In some cases, multiple attempts may be necessary. Cardioversion is a common and effective treatment for arrhythmias like atrial fibrillation and supraventricular tachycardia.
