Arrhythmias are electrical disorders of the heart that cause irregular heart rhythms. They may occur as tachycardia (rapid heart rate), bradycardia (slow heart rate), or irregular beats, and may be due to structural heart disease, electrolyte disturbances, genetic predisposition, or lifestyle factors.

Some of the common arrhythmias are atrial fibrillation (AF), ventricular tachycardia (VT), supraventricular tachycardia (SVT), and bradyarrhythmias. The most common one is atrial fibrillation, which is also the biggest risk factor for stroke and heart failure, while ventricular arrhythmias can prove fatal if not treated early enough. The symptoms range from palpitations, dizziness, and shortness of breath to syncope or sudden cardiac arrest in more severe situations.

Diagnosis is based on clinical assessment, electrocardiography (ECG), Holter monitoring, event recorders, and electrophysiology testing. Identification of the type of arrhythmia is important in choosing the correct management strategy.

Arrhythmia management is determined by type, severity, and etiology. The use of pharmacological agents can involve antiarrhythmic medications, beta-blockers, or anticoagulants to prevent thromboembolism. Refractory arrhythmias can be treated by interventional means with catheter ablation as a less invasive option. Patients with extensive bradycardia or potential for sudden cardiac death are candidates for pacemakers or ICDs.

With improvements in electrophysiology and remote monitoring technologies, management of arrhythmia has become more specific, individualized, and efficient, enhancing patient outcomes and long-term cardiovascular health.
