Arrhythmia Treatment in Raipur

An arrhythmia is any disturbance in the normal rhythm of the heart, either too fast (tachyarrhythmia), too slow (bradyarrhythmia) or irregular. The heart's electrical system generates and conducts impulses that co-ordinate each heartbeat; disruption produces arrhythmias ranging from benign palpitations to life-threatening ventricular fibrillation. Arrhythmias are among the most common cardiac conditions in India. Ramkrishna CARE Hospitals, Raipur provides complete arrhythmia diagnosis, electrophysiological assessment, and interventional treatment.

Types of Arrhythmia

Arrhythmias are classified by their origin in the heart and whether the rate is too fast, too slow, or irregular.

• Supraventricular arrhythmias: Originating above the ventricles (the main pumping chambers) include:
• Atrial fibrillation: A chaotic, irregular atrial rhythm
• Atrial flutter: A rapid organised atrial rhythm at around 300 beats per minute
• Supraventricular tachycardia: Sudden-onset rapid heartbeat from a re-entry circuit in the AV node or accessory pathway
• Wolff-Parkinson-White syndrome: A congenital accessory electrical pathway bypassing the AV node, predisposing to very fast heart rates.
• Ventricular arrhythmias: Originate in the ventricles and are generally more dangerous. They are:
• Ventricular tachycardia: It is a rapid rhythm originating in the ventricular muscle, often above 150 beats per minute and can be haemodynamically stable or cause collapse. 
• Ventricular fibrillation: VF is disorganised ventricular electrical activity producing no effective cardiac output and causes cardiac arrest and requires immediate defibrillation. 
• Bradyarrhythmias: Includes sick sinus syndrome and complete heart block (where no impulses pass from the atria to the ventricles) cause the heart to beat too slowly, producing dizziness, syncope and heart failure.

Symptoms of Arrhythmia

Symptoms depend on the arrhythmia type and how much it affects the heart's ability to pump blood effectively.

• Palpitations or an awareness of a racing, fluttering, or pounding heartbeat
• Frequent ectopic beats (isolated premature heartbeats)
• Dizziness
• Lightheadedness
• Syncope (sudden loss of consciousness) 
• Breathlessness, chest pain and fatigue indicate significant haemodynamic impairment. 
• Cardiac arrest (no pulse) is the presenting event in ventricular fibrillation. 
• Some arrhythmias including AF and dangerous ventricular arrhythmias can be entirely asymptomatic.

Causes of Arrhythmia

Arrhythmias arise when the heart's electrical system is disrupted by structural disease, metabolic disturbance, or congenital abnormality. Common causes are:

• Coronary artery disease (CAD) and prior myocardial infarction (heart attack) cause myocardial scarring that forms re-entry substrates for VT and VF. 
• Cardiomyopathy is a major cause of life-threatening ventricular arrhythmias. 
• Rheumatic heart disease and valvular disease cause atrial dilatation (stretching of the upper chambers), predisposing to AF and atrial flutter. 
• Electrolyte disturbances (low potassium, magnesium, or calcium), thyroid disease, excess alcohol and certain medicines (digoxin, QT-prolonging drugs) are important reversible causes.

Diagnosis of Arrhythmia

Accurate diagnosis requires capturing the arrhythmia on an ECG and assessing the underlying cardiac structure and function.

• 12-lead ECG (electrocardiogram): Identify AF, atrial flutter, heart block, bundle branch block and WPW pre-excitation. 
• Holter monitoring: Continuous ECG recording over 24 to 48 hours, or up to 14 days with a patch monitor captures intermittent arrhythmias not present on the standard ECG. 
• Electrophysiology study (EPS): A catheter-based procedure in which electrode catheters are introduced through the femoral vein to map the cardiac electrical system, diagnose and localise arrhythmia circuits before ablation. 
• Echocardiography: Assesses cardiac structure and function.

Treatment for Arrhythmia

Treatment is tailored to the arrhythmia type, its symptoms and the risk it poses to the patient.

• Medications: Antiarrhythmic medicines modify the heart's electrical properties. 
  • Rate-controlling medicines (beta-blockers, rate-limiting calcium channel blockers, digoxin) slow the ventricular rate in AF without restoring the sinus rhythm. 
  • Rhythm-controlling medicines restore and maintain normal sinus rhythm. 
  • Anticoagulation is mandatory in AF and reduces stroke risk.
• Catheter ablation: Delivers radiofrequency energy or cryoenergy through a catheter to destroy the abnormal electrical tissue causing the arrhythmia. It is curative for most SVT and typical atrial flutter and highly effective for paroxysmal atrial fibrilation. 
• Implantable cardioverter-defibrillator: Doctors implant ICD under the skin to monitors rhythm and delivers an internal shock to terminate VT or VF. It is indicated for survivors of cardiac arrest and high risk patients with cardiomyopathy. 
• Pacemaker: Permanent pacemaker implantation treats symptomatic bradyarrhythmias including sick sinus syndrome and complete heart block.

Risk Factors for Arrhythmia

Several modifiable risk factors contribute to arrhythmia development; addressing them reduces both incidence and recurrence. They are:

• Coronary artery disease, heart failure, and cardiomyopathy are the strongest risk factors for life-threatening ventricular arrhythmias. 
• Hypertension and valvular heart disease are the leading causes of AF. Modifiable risk factors for arrhythmia include 
• Obesity (BMI above 30 kg/m²)
• Obstructive sleep apnoea 
• Alcohol intake above two standard drinks per day
• Physical inactivity
• Poorly controlled diabetes. 
• Congenital heart disease, thyroid disease and stimulant use are additional modifiable contributors.

Complications of Arrhythmia

Untreated or inadequately managed arrhythmias can cause severe cardiovascular complications:

• Dizziness
• Progressive left ventricular dysfunction
• Tachycardia-induced cardiomyopathy
• Organ damage due to poor blood flow
• Stroke  
• Cardiac arrest.
