![]() ![]() This leads to impulses being slowed or blocked.Ī premature heartbeat is an extra beat that can feel like a skipped heartbeat. It can occur in or near the AV node, or along other pathways to each ventricle. This refers to a blockage of your heart’s electrical pathway. When this happens, your heart may alternate between beating too fast or too slow. This occurs when the sinus node that is responsible for setting a regular rhythm fails to send impulses properly. Most people who experience ventricular fibrillation have underlying heart disease.īradycardia refers to a slow heartbeat with a resting rate of over 60 beats per minute. This occurs when rapid, chaotic electrical impulses cause the ventricles to quiver ineffectively instead of pumping blood to the body. This makes it difficult to pump enough blood to the body. This is a rapid, regular heart rate that does not allow the ventricles to fill and contract efficiently. They may cause sudden episodes of palpitations that begin and end abruptly. These arrhythmias originate above the ventricles in the atria or AV node. It broadly refers to many forms of arrhythmia. This is caused by irregular electrical impulses. ![]() Tachycardia refers to a fast heartbeat with a resting rate of over 100 beats per minute. There are 3 types of heart arrhythmias: Tachycardia Others experience more severe symptoms that can be life-threatening. Some people experience this as a fluttering or racing heart. This causes the heart to beat too fast, too slow or irregularly. A slight delay allows the ventricles to fill with blood before they contract and pump blood to the lungs and the rest of the body.Ī heart arrhythmia occurs when the electrical impulses are not coordinated. ![]() It produces an electrical impulse that stimulates the atria muscles to contract and pump blood into the ventricles. Under normal circumstances, the sinus node in the right atrium of the heart acts as a natural pacemaker. A heart arrhythmia refers to an irregular heartbeat. ![]()
