Arrhythmias

Arrhythmias are aberrant cardiac rhythms brought on by irregular electrical impulses regulating the pulse. The heart may beat too rapidly (tachycardia), too slowly (bradycardia), or irregularly (fibrillation) from these disruptions. Arrhythmias can be either transitory or persistent, and they start in the ventricles or atria.
Among the common causes of arrhythmias are coronary artery disease, high blood pressure, electrolyte abnormalities, cardiac attacks, too much alcohol or coffee, stress, and underlying heart disorders. Though they differ, symptoms could be palpitations, vertigo, dyspnoea, chest pain, or even fainting. While ventricular arrhythmias can be fatal, several arrhythmias—including atrial fibrillation—raise the risk of stroke.
Diagnosis calls for electrophysiological testing, Holter monitoring, stress tests, and electrocardiograms (ECG). The nature and degree of the arrhythmia will determine the treatment. In severe cases it could call for pacemakers, catheter ablation, beta-blockers or antiarrhythmic medicines, or implantable defibrillators.
Maintaining a healthy heart through a balanced diet, consistent exercise, stress management, and avoiding overly strong stimulants can prevent arrhythmias. Managing the illness and avoiding major problems like heart failure or sudden cardiac arrest depend on early discovery and treatment.
