The atria, or upper chambers of the heart, act as blood receptacles, while the ventricles, or lower chambers, pump blood in and out of the heart. An electrical impulse originates in the right atrium and causes the heartbeat. The electrical activity travels through the atria’s walls, causing them to compress and force blood into the ventricles. London Heart Clinic has a team of heart rhythm specialists that can help you understand the condition of your heart properly.

Different types of disorders in the rhythms of heart
Arrhythmias, or irregular heartbeats, are defined by the region of the heart where they occur as well as the type of abnormal heartbeat they induce, such as tachycardia (an abnormally fast heartbeat) or bradycardia (an abnormally slow heartbeat) (abnormally slow heartbeat).
Afib is a quick, erratic heartbeat triggered by chaotic electrical impulses in the atrium of the heart. It is estimated that one out of every ten people aged 65 and up is affected. Even if atrial fibrillation is only acute and asymptomatic, it may cause severe problems such as stroke. Anticoagulants and left atrial occlusion systems are used to avoid strokes, whereas antiarrhythmic medications and ablation are used to treat atrial fibrillation.
AFib is similar to atrial flutter, but the irregular pulse is more frequent and can last for days or even weeks. Ablation treatments for atrial fibrillation can cause atrial flutter in a limited percentage of people when the heart creates new electrical pathways to bypass the treated area. Although atrial flutter can cause severe complications, it is usually easy to treat.
It refers to arrhythmias that originate in the heart’s upper chambers. An extra electrical pathway connects the atria and ventricles, allowing impulses to circumvent the heart’s normal course, resulting in abnormally fast heartbeats. These arrhythmias are usually not life-threatening, but they can be aggravating. To restore the heart’s natural rhythm, medical medication or cardioversion therapy may be needed. Ablation is also used to cure diseases.
Abnormal electrical impulses in the ventricles keep them from filling and circulating blood properly in ventricular tachycardia. Ventricular tachycardia can progress to ventricular fibrillation, a medical emergency that can result in premature death if not treated promptly. Ventricular fibrillation occurs as the ventricles quiver chaotically and ineffectively instead of pumping blood.
Hypertrophic cardiomyopathy (HCM)
It is a rare but normal cardiac hereditary disease in which the heart muscle thickens. In young adults and athletes, it is the most frequent cause of sudden cardiac death. Atherosclerosis puts people with HCM at risk for atrial fibrillation and heart failure.
Another cause of sudden cardiac death in athletes and others is arrhythmogenic right ventricular dysplasia (ARVD). Hypertrophic cardiomyopathy is more common, but it is less common. ARVD patients are at risk of developing heart disease.
Long QT syndrome increases a person’s risk of rapid, chaotic heartbeats, which can induce fainting and be fatal.
Follow-up monitoring lets people stick to their post-treatment protocols and ensures a smooth recovery after arrhythmia has been treated with medicine, surgery, or both. Nurse practitioners with advanced experience in electrophysiology and arrhythmias are on hand to provide supervision and assistance, as well as to address any questions that patients may have. Patients are supported by team members who work closely with them to learn how to successfully resume their wellness routines and make healthy lifestyle improvements.
