Arrhythmias are irregularities in the heart’s rhythm, which can cause the heart to beat too fast, too slow, or irregularly. These disturbances can affect the heart’s ability to pump blood efficiently, potentially leading to symptoms such as palpitations, dizziness, shortness of breath, and even fainting.
Arrhythmias can be classified into several types based on their origin and effect on the heart. Tachycardias are arrhythmias characterized by an abnormally fast heart rate, while bradycardias involve a slower-than-normal heart rate. Premature beats, such as premature atrial contractions (PACs) or premature ventricular contractions (PVCs), occur when extra beats disrupt the regular heart rhythm.
Diagnosis of arrhythmias typically involves electrocardiogram (ECG) monitoring, Holter monitoring, and event recorders to capture and analyze the heart’s electrical activity. Treatment options vary based on the type and severity of the arrhythmia and may include lifestyle changes, medications, and medical procedures such as cardiac ablation or the implantation of a pacemaker or defibrillator.
Managing arrhythmias often requires ongoing monitoring and adjustment of treatment to ensure optimal heart function and prevent complications.
