Understanding Cardiac Arrhythmias: Symptoms, Causes, and Treatments

December 28, 2024 | 5 mins read

Cardiac arrhythmias are conditions where the heart beats irregularly—either too fast, too slow, or with an inconsistent rhythm. These disruptions can significantly impact heart function and overall health. This article delves into the types, symptoms, causes, and the latest advancements in treatment options for arrhythmias, with insights from leading cardiologists in Delhi.

Types of Cardiac Arrhythmias

1. Bradycardia: A slower-than-normal heart rate, typically below 60 beats per minute. Symptoms likes fatigue, dizziness, fainting spells etc.
2. Tachycardia: A rapid heart rate exceeding 100 beats per minute. It can originate in the atria (supraventricular) or ventricles (ventricular tachycardia).
3. Atrial Fibrillation (AFib): A common arrhythmia where the atria beat irregularly, increasing the risk of stroke.
4. Ventricular Fibrillation: A life-threatening condition causing chaotic heartbeats, requiring immediate intervention.

Symptoms of Cardiac Arrhythmias

Some arrhythmias may not present any symptoms, but common signs include:

• Palpitations or fluttering in the chest
• Shortness of breath
• Dizziness or fainting
• Chest discomfort
• Fatigue

Severe cases may lead to sudden cardiac arrest, highlighting the need for timely diagnosis and treatment.

Causes of Cardiac Arrhythmias

Arrhythmias can stem from various factors, including:

• Heart diseases such as coronary artery disease or structural abnormalities
• Electrolyte imbalances disrupting electrical signals in the heart
• Excessive caffeine, alcohol, or stress
• Certain medications

Advanced diagnostic techniques like ECG, Holter monitoring, and electrophysiological studies help identify the root cause.

Advanced Treatment Options

Modern treatments for arrhythmias focus on restoring and maintaining a normal heart rhythm. These include:

• Medications: Antiarrhythmic drugs to regulate heartbeats
• Catheter Ablation: A minimally invasive procedure to target and destroy abnormal heart tissue
• Pacemakers and ICDs: Devices implanted to control irregular heart rhythms
• Lifestyle Modifications: Managing stress, diet, and exercise
