Understanding Arrhythmia on ECG
Introduction
Arrhythmia refers to an irregular heartbeat, which can be too fast (tachycardia), too slow (bradycardia), or simply irregular. An electrocardiogram (ECG) is a crucial tool for diagnosing different types of arrhythmias.
How ECG Helps Detect Arrhythmias
ECG records the electrical activity of your heart and provides essential details about your heart rate and rhythm. By analyzing ECG waveforms such as P waves, QRS complexes, and T waves, doctors can identify different arrhythmias.
Common Types of Arrhythmias and Their ECG Features
- Atrial Fibrillation (AF): Absent P waves, irregularly irregular rhythm.
- Atrial Flutter: Sawtooth pattern of P waves.
- Supraventricular Tachycardia (SVT): Narrow QRS complexes, absent or hidden P waves.
- Ventricular Tachycardia (VT): Wide QRS complexes, no visible P waves.
- Ventricular Fibrillation (VF): Chaotic, irregular ECG pattern without identifiable waves.
- Heart Block:
- First-degree: Prolonged PR interval.
- Second-degree (Mobitz I and II): Progressive PR prolongation (Type I) or dropped beats (Type II).
- Third-degree: Complete dissociation between P waves and QRS complexes.
Importance of Identifying Arrhythmias
Recognizing arrhythmias early is essential because some can be life-threatening and require immediate intervention, such as defibrillation or pacemaker implantation.
Conclusion
If you experience symptoms like palpitations, dizziness, or fainting, seek medical attention. ECG interpretation by a cardiologist can help diagnose and manage arrhythmias effectively.
