Arrhythmias (Atrial Fibrillation, Tachycardia)

Arrhythmia

Arrhythmia is a condition where the heart beats irregularly too fast, too slow, or unevenly. It occurs due to disruptions in the heart’s electrical signals, affecting its ability to pump blood efficiently. Arrhythmias can be harmless or life-threatening, depending on the type and severity. Common types include atrial fibrillation, bradycardia, tachycardia, ventricular fibrillation, and supraventricular arrhythmias.

Why Choose Aster Hospitals for Arrhythmia Treatment?

Aster Hospitals specializes in comprehensive arrhythmia management, offering advanced electrophysiology studies, catheter ablation, pacemaker and defibrillator implantation, and 24/7 emergency cardiac care. The hospital’s team of experienced cardiologists and electrophysiologists ensures accurate diagnosis and personalized treatment for optimal heart health.

Signs and Symptoms

  • Irregular Heartbeat: Skipped, fast, or slow heartbeats.
  • Palpitations: A fluttering sensation or pounding in the chest.
  • Dizziness or Lightheadedness: Due to inadequate blood supply to the brain.
  • Shortness of Breath: Difficulty breathing, especially during exertion.
  • Chest Pain or Discomfort: Often a sign of a severe arrhythmia.
  • Fatigue and Weakness: Lack of proper circulation reduces energy levels.
  • Fainting (Syncope): Sudden loss of consciousness due to poor blood flow.

Types

Tachycardia (Fast Heart Rate)

  • Supraventricular Tachycardia (SVT): Rapid heartbeats originating above the ventricles.
  • Atrial Fibrillation (AFib): Irregular, chaotic beating of the atria.
  • Ventricular Tachycardia: A fast, abnormal rhythm in the lower heart chambers.

Bradycardia (Slow Heart Rate)

  • Sinus Bradycardia: Slow but steady heartbeat.
  • Heart Block: Signal disruptions causing the heart to beat too slowly.

Fibrillation (Irregular Heartbeat)

  • Atrial Fibrillation (AFib): Increases stroke risk due to blood pooling.
  • Ventricular Fibrillation: A life-threatening emergency requiring immediate defibrillation.

Treatment Options

Medications:

  • Antiarrhythmic Drugs: Help regulate heart rhythm.
  • Beta-Blockers & Calcium Channel Blockers: Control heart rate.
  • Blood Thinners: Reduce stroke risk in atrial fibrillation.

Non-Surgical Procedures:

  • Catheter Ablation: Destroys abnormal heart tissue causing arrhythmias.
  • Electrical Cardioversion: Uses controlled shocks to restore normal rhythm.

Surgical Treatments:

  • Pacemaker Implantation: Regulates slow heart rhythms.

FAQ's

Want to find out more about the treatment? The answer to your questions can be found below.

What are the warning signs of an arrhythmia?

Common signs include palpitations, dizziness, shortness of breath, chest discomfort, and fainting, which require immediate medical evaluation.

How are arrhythmias diagnosed?

Tests like ECG, Holter monitoring, echocardiograms, and electrophysiology studies help detect abnormal heart rhythms.

When is a pacemaker needed for arrhythmia treatment?

A pacemaker is required when the heart beats too slowly, causing symptoms like dizziness, fainting, and fatigue.

Can arrhythmias be life-threatening?

Some arrhythmias, like ventricular fibrillation, can cause sudden cardiac arrest, while others may be harmless but require monitoring.

What lifestyle changes can help manage arrhythmias?

Avoiding caffeine, alcohol, smoking, and stress, along with regular exercise and a heart-healthy diet, can help control arrhythmias.
