Ventricular arrhythmias begin in the heart’s two lower chambers, the ventricles. Normally, your heartbeat starts in the atria (upper heart chambers) and spreads throughout the heart through its electrical system. Se hela listan på On the causes of ventricular arrhythmia, its treatment and outcome considerable contribution of Na+-K - ATPase, which actively transports sodium out of the cell and potassium into the cell. In the same phases, the electrogenic Na+-Ca++ exchanger (NCX) is activated according to the concentrations of calcium and sodium inside the cell. Ventricular arrhythmias are abnormal heartbeats that originate in your lower heart chambers, called ventricles. These types of arrhythmias cause your heart to beat too fast, which prevents oxygen-rich blood from circulating to the brain and body and may result in cardiac arrest.

Often, only reassessment of ventricular function after ablation of the arrhythmia clarifies the cause. Se hela listan på Se hela listan på The principal cause of sudden death is the occurrence of malignant cardiac arrhythmias, which result in the loss of contraction of the heart with subsequent lack of blood supply to vital organs like the brain. The immediate consequence is loss of conscience, and if the arrhythmia persists for more than 5 minutes, the patient dies. Arrhythmias can also be caused by certain substances or medications, such as caffeine, nicotine, alcohol, cocaine, inhaled aerosols, diet pills, and cough and cold remedies. Emotional states such as shock, fright or stress can also cause irregular heart rhythms. ventricular arrhythmia causes Other conditions such as a low potassium or sodium levels in the blood and hypothermia or a very low body temperature can cause arrhythmia. Some anti-arrhythmic drugs can also accidentally trigger this condition, so doctors must also check if the patient is taking other forms of medication which may have contraindications.

Heart arrhythmias fall into two categories. One starts from inside the heart's lower chambers.
